Rated 5 out of 5 by from Superb all-season tire Best all season tire I've ever owned. The Primacy MXM4 isn't perfect nor even best in class in any single category, but is a standout because it excels in all (disclaimer: I don't live in the snow belt and haven't driven them in snow). The tire provides a superb balance between ride comfort and control... taught and confidence inspiring while being comfortable. For a non-directional tread its hydroplaning resistance is excellent and for an all season its lateral wet grip is exceptional. Dry grip is excellent for a tire in this class. It's also the quietest tire I've ever owned. Good, even wear. Will continue to buy this or successor.

Rated 5 out of 5 by from Primacy MXM4- 2012 Acrua TL (Base) This is my second set of Primacy MXM4's (P245/ 50R17) for my 2012 Acura TL (Base) model, which were replaced on 7-2-16. Through proper maintenance (rotation of tires between 5,000 to 6,000 miles and recommended tire pressure per manufacturer at 32 psi), I was able to obtain 63,000 miles and probably could have got another 5,000 to 7,000 miles (replaced with 4/32 " tread depth still available). My driving consist of a mixture of highway and city driving. The ride comfort and wet traction is excellent. I can't speak well on snow traction being in NC, but when snow and ice were present, the Primacy MXM4s held up well.

Rated 5 out of 5 by from Great Tires These were OEM on Lexus ct 200h and I was very impressed when they were new. They were quiet and handled very well from the beginning (I am pretty hard of hearing, 'quiet' is a relative term) but most impressive is their handling when worn. I live in Washington State so drive in wet conditions regularly and these handled rain and standing water, at all speeds, extremely well when up to 95% worn. I have 58k miles on them now and trying to get 1-2k more. Not sure how to judge their assistance with fuel efficiency but will say that over the life of the tires I avg. 45-46mpg. Will definitely replace with the same.

Rated 5 out of 5 by from PERFECTO!! This is the second set of this particular tires that I have owned. The first set were on my first, brand new 2007 Acura TSX and the performance these tires showed just couldn't be compared to any other brands. I refused to put any other tire on that car other than these. I just last month purchased a 2016 Acura RDX and it already came stock with this brand and model of tire on it and I was sooooo happy about that because I knew I had a good set of tires on this vehicle. My wife went on a road trip and she was happy about how quiet and smooth the ride was. Then I went on a road trip and I certainly didn't have to guess how well that went!!!

Rated 5 out of 5 by from Incredible reliability, wear and value I drive a 2013 Honda Accord Sport and these tires came on my vehicle. I would say I drive pretty moderately so you have a reference of how hard I was on the tires. I currently have over 94,000 miles on these tires. That's not a misprint. For a 55,000 mile tire you wont get a better one out there. I am getting a new set since winter is coming here in Washington State and the roads are getting worse. If it was springtime I would probably wait as they still have adequate tread left. Some road noise with these tires is the only negative I would have. Yes they are more money than most tires, worth every cent in my opinion.

Rated 5 out of 5 by from Sure Footed and Reliable Drove to Lake George, NY from Jupiter, FL-total of 7,100 miles round trip. Hit white squalls near JAX(Similar to winter white outs). Remainder of trip was mostly dry w/occasional heavy rains. Never once hydroplaned or skidded. Smooth, soft, quiet ride...although tire pressure was 6# low. Local WPB dealer forgot to check tire pressure during tire rotation, nor did they check windshield washer fluid. Added proper air pressure for return trip and noted firmer, more responsive handling. Great stopping/slowing when required as drivers occasionally drifted/changed lanes with out looking. I'll remain a loyal customer!

Rated 5 out of 5 by from Primacy MXM4 255/40R17 94H The Michelin Primacy MXM4 have been the best tires all around I have owned. I drive 40,000 miles a year in all weather conditions from mountain snow and ice to heavy Oregon coastal storms. I have mismatched front and rear tires on my Mercedes CLK and the rear tires currently have 42,000 miles on them but are getting close to replacement in the next 3-5,000 miles. The front tires have more than 50% tread left at 56,000 miles. The last set of MXM4 tires on the front were changed out at 80,000 miles. The MXM4 tires stick to the road like glue on hard cornering. These are impressive tires!

Rated 5 out of 5 by from Michelin Primacy tires exceeded expectations These tires came new on my 2014 Cadillac Performance Model sedan with the 3.6L engine. They have been quiet and handle extremely well as this car has an awesome chassis and these tires don't hinder performance. I just bought another set of MXM4s after 33,000 miles. I probably could have gotten several thousand more miles but I will be selling this car and I wanted to buyer to experience what fine tires these are and what a great car this Cadillac ATS is. I will be buying a new Corvette Z06 which comes with Michelin tires (very pleased) hope it comes with Michelin's Pilot PS4. My other Cadillac an SRX Premium has 20" Michelin Premiers *****

Speed Rating:

The speed rating is a measure of what speed the tire can safely maintain for sustained periods of time. A higher speed rating will generally indicate that you will have better control and handling characteristics. Speed rating standards are established by the U.S. Department of Transportation (DOT). Manufacturers assign speed ratings to tires after extensive performance testing. On the sidewall of every tire, you’ll find one of these speed rating codes:

M – Up to 81 mph
N – Up to 87 mph
P – Up to 93 mph
Q – Up to 99 mph
R – Up to 106 mph
S – Up to 112 mph
T – Up to 118 mph
H – Up to 130 mph
V – Up to 149 mph
W – Up to 168 mph
Y – Up to 186 mph
Z – (See Below)

What does ‘Up to 99 mph’ really mean?
Tires with a Q speed rating can safely sustain speeds of up to 99 miles per hour. The tire may be able to reach higher speeds, but traveling at speeds higher than 99 mph for any length of time would be unsafe - the tire is not designed to handle it.

What is a Z Rating?
For tires having a maximum speed capability above 149 mph, a Z rating may appear in the size designation ...above 186 mph, a Z rating must appear in the size designation, including a Y speed symbol in brackets.

A Few Tips About Speed Ratings…
Never mix tires with different speed ratings, as this may cause serious handling problems.

We don’t recommend downgrading the speed rating of your tires, as the vehicle manufacturer has done extensive testing to determine which tires match the various driving characteristics of the vehicle. However, if you are looking for better handling, there is generally no problem in moving up to a higher speed-rated tire.

Most importantly: Put safety first. The speeds shown are test speeds; they are not recommended speeds.

Temperature Rating:

A comparative grade based on the tire’s resistance to heat and its ability to dissipate heat, again as measured under controlled conditions. The grades, from highest to lowest, are designated A – B – C. An A-rated tire is the coolest running, while a C-rating meets the minimum federal performance standards. These temperature grades are set based on a tire that is properly inflated and not overloaded.

Traction Grade:

A comparative grade based on the tire’s ability to stop on wet pavement, again as measured under controlled conditions on wet asphalt and concrete surfaces. The grades, from highest to lowest, are designated AA – A – B – C. A tire that is graded AA should have better traction or stopping performance than a tire with a lower grade, based on the specific straight-ahead braking tests.

Treadwear Grade:

A comparative grade based on the actual wear of the tire’s tread when tested under specific controlled conditions. All tires are tested under the same conditions to allow for comparison between manufacturers and between different lines of tires from the same manufacturer. The system is fairly easy to understand. A tire with a treadwear grade of 400 should have a useful tread life approximately twice as long as a tire with a treadwear grade of 200. The higher the grade, the better the expected treadwear.

Looking for new tires with optimal traction? Or are long-lasting treads a bigger priority? There’s a simple way to compare tire specs!

The Uniform Tire Quality Grading (UTQG) system was developed by the Department of Transportation (DOT) to assist consumers in the purchase of their tires by providing a standard grading system used by all tire manufacturers. Tire manufacturers use the UTQG system to grade their tires in three important areas: treadwear, traction and temperature. The UTQG grade for each tire is shown on the paper label affixed to the tire and is also molded in the sidewall.

Treadwear Grade – A comparative grade based on the actual wear of the tire’s tread when tested under specific controlled conditions. All tires are tested under the same conditions to allow for comparison between manufacturers and between different lines of tires from the same manufacturer. The system is fairly easy to understand. A tire with a treadwear grade of 400 should have a useful tread life approximately twice as long as a tire with a treadwear grade of 200. The higher the grade, the better the expected treadwear.

Traction Grade – A comparative grade based on the tire’s ability to stop on wet pavement, again as measured under controlled conditions on wet asphalt and concrete surfaces. The grades, from highest to lowest, are designated AA ABC. A tire that is graded AA should have better traction or stopping performance than a tire with a lower grade, based on the specific straight-ahead braking tests.

Temperature Grade – A comparative grade based on the tire’s resistance to heat and its ability to dissipate heat, again as measured under controlled conditions. The grades, from highest to lowest, are designated ABC. An A-rated tire is the coolest running, while a C-rating meets the minimum federal performance standards. These temperature grades are set based on a tire that is properly inflated and not overloaded.

UTQG is a great way to compare tires from various manufacturers and between specific lines from the same manufacturer. Remember: The UTQG isn’t a safety rating and it doesn’t guarantee a tire’s mileage performance - but you can use the UTQG in conjunction with price, warranty, appearance and recommendations to make the right tire choice for your needs. If you have any questions about UTQG or various tire lines, the Big O Tires team is always ready to help!

Hauling groceries – or bricks? The Load Rating or Load Index indicates how much weight each tire can safely support.

Every tire’s load rating is stamped into its sidewall. Once you know the load rating, you can use the chart below to determine the amount of weight that one tire can support. Then just multiply the weight by four - or the number of wheels on your vehicle - to determine your vehicle’s maximum load-carrying capacity.

Load Rating Table

Sometimes the maximum load (for example, 1060 kg) will be stamped into the sidewall so that you don't have to decipher the load rating. Remember: never install tires with a lower load-carrying capacity than the tires that were installed on your vehicle by the manufacturer!

Load Range:

The load rating is a measure of the tire's strength — its ability to hold air pressure under load.

The load rating influences the sidewall strength of a vehicle tire. If a tire has a load rating that is too low, the handling of the vehicle could become unstable as the sidewall buckles under the vehicle's weight. Conversely, a much higher load rating than needed can dramatically harshen ride quality.

The recommended load rating for a vehicle's tires can be found in its owner's manual. It is also normally affixed to a sticker located on one of the vehicle's door jams. If you are replacing tires supplied with the vehicle from the manufacturer, the load rating written on the tires is an appropriate guide.

Sidewall:

There are other codes on some tires that provide you with additional information, some of which are specific to light truck tire applications. Some of the other codes that you might find on your tires include:

LT = Stands for light truck application. Example: LT235/85R16
C, D or E = Load range indication for light truck applications
REIN = Reinforced
OWL = Outlined White Letters
RWL = Raised White Letters
ORWL = Outlined Raised White Letters
B, BLK, BW, BSW = Blackwall or Black Sidewall
W, WW, WSE – Whitewall or White Sidewall
XNW = Extra Narrow White Width
XL = Extra Load Capacity

Section Width:

The linear distance between the outside sidewalls of an inflated tire without any load (exclusive of protruding side ribs and decorations).

Sidewall Aspect Ratio:

The ratio between tire height and width.

Important note on quoted prices:

Prices quoted do not include additional charges for sales taxes, mounting and balancing, valve stems, tire disposal fees, state recycling fees, tire protection plans and other charges. Prices may vary from one store to another or from one date to another. Tires listed may not be in stock at the identified store.

Please call the Big O Store of your choice for up-to-date information and details on pricing, additional charges and product availability.

How Are Tire Sizes Specified?
The first number describes width of the tire (section), the second number describes the aspect ratio (profile), and the third number the wheel diameter (rim size).
Alignment makes a big difference in how long tires last, how much gas you use, and steering and safety. When you buy new tires, we'll make sure they're properly aligned with a free alignment check!

What is TPMS?


TPMS is an electronic system that monitors the air pressure in your tires and alerts you when they are under- or over-inflated. Proper tire inflation not only boosts your safety, but also the life of the tire and its fuel economy.

TPMS

Some components of the TPMS sensor may need to be replaced due to wear and corrosion over time. Our TPMS rebuild kit includes all the necessary parts to service your TPMS sensor and keep this important safety feature functioning properly.
