Sumitomo's HTR Z III. Are you looking for an excellent max performance summer tire at a friendly price? If so, the Sumitomo High Performance HTR Z III is your Tire. The aggressively designed HTR Z III delivers extraordinary performance in both wet or dry conditions, on and off the track.

Innovative Tread Design. The Sumitomo HTR Z III is the perfect summer performance tire for any Mustang. With an asymmetric 5-rib directional tread pattern, reinforced construction, and innovative traction features, the HTR Z III will provide uncompromised handling. Additional features include large outboard shoulders and intermediate tread blocks along with continuous center and inboard intermediate ribs to provide white-knuckle handling.

Summer Performance Compound. Sumitomo's HTR Z III Tires feature a unique compound that is specifically designed for track and performance applications. The silica-enhanced tread compound provides excellent dry traction making the HTR Z III the "go-fast" rubber your Mustang needs to stick to the track.

Excellent Wet Traction. Long lateral grooves of the HTR Z III evacuate water from the center of the footprint, where four straight, wide grooves further heighten drainage for improved wet performance. A 3-D wave wall increases drainage capabilities and reinforces center rib stability, while siped tie-bars reinforce block rigidity for control and enhance wet traction.

Smooth Ride; Minimal Noise. In addition to outstanding performance, HTR Z III Series Tires deliver a smooth ride with minimal road noise. That way you and your passengers can be treated to the sounds that really count, like the growl of your motor, the whine of your supercharger, or the bass thumping from your Mach 1000 stereo system!

5 Year Warranty. The Sumitomo High Performance HTR Z III Tire comes with a 5-year warranty from the date of purchase. Some limitations do apply. Please see the Full Sumitomo Warranty disclosure for details.

Application. The Sumitomo High Performance HTR Z III Tire is designed for use on 1979-2018 Mustangs. Please choose your size from the ordering options above. Sold individually.

NOTE: These are ultra high performance summer specific compound and tread tires. Use during the summer and warm temperature months will result in superior traction over "all season" tires. Use during the winter months/cold temperatures significantly reduces traction and increases stopping distance as the compound becomes less sticky.

I have a 19x10 wheel, can the 275 fit on my wheel or it would be too small?

Strahtoz

  • The 275/40R19 Sumitomo High Performance HTR Z III Tire has an approved Rim size of 9"-11" and would fit your 19x10 without issues.

I see other answers stating that a 255 wide tire will fit a 8 inch wheel. I have 19x8.5 and curious if a 275 would fit my wheels?

RGT3

  • A 275 will most likely be too wide for your 19x8.5" wheel, but will vary from tire manufacturer to tire manufacturer. Most 275's are only approved for 9" wide to 11" Wide wheels.

I have a 2008 Mustang GT, it has 235/50/18 size tires on it now, I would like a lower profile and a wider tire, what size can I upgrade to, without them causing any problems?

LarryS

  • Thank you for your question. To eliminate any possible problems that could be causes by running a wider tire or one with less sidewall profile on your stock wheels, we would recommend plus sizing your wheels. The most important thing when looking to change your wheel and tire specs is to try and maintain the overall diameter of the original set. Your 235/50R18 is 27.3 inches. Decreasing the profile of the tire on your 18 wheel will cause your speedometer to read the incorrect speed. Increasing the width of the tire without changing to a wider wheel will cause uneven tread wear on the tread wearing faster in the center. You can find our wheel and tire guide in the link below for our recommended sizes. 2005-2012 Wheel & Tire Fitment: http://www.americanmuscle.com/05-09-tire-sizes.html

What is the temperature range on these? I live in South Louisiana and I was wondering if these could be used year round. It rarely gets below 40°F down here.

    If you are looking for a performance tire, don't look here, this tire has good grip, that is why I gave it 2 stars instead of 1, but that is where the performance ends! The sidewalls are sooooooo soft, they put all the body roll back into my custom suspension. There is a reason they are cheaper!! Put out the extra money for a real performance tire! If you want a tire that has good grip but rides like a stock tire then this is for you, but if you want to feel the road and no body roll then look somewhere else!!

It hook up so WELL and taking courners its like a video game. I guess the old saying is true..."Wide-er is better". Of course this isn't the tire if you have tons of snow on the ground.WIth these tires, you will make people think twice about steping next to you. ... so I can just imagine how it will handle when it gets warmer. The looks of this huge wide tire... it makes people wonder what you have under the hood. In my personal opinion, you will NOT feel bad about buying these tires!

    Review from Sumitomo High Performance HTR Z III Tire - 245/45R19 (05-18 All)

    Super sticky tires!

    I ordered these tires paired with AMR wheels, same 245/45/19 size all around. I have been very pleased with the way these tires handle. PROS: In dry conditions, traction with 3.73s and these sumitomo tires is better than with 2.73s on hard skinny stock tires. I've run these tires at the 1/4 mile track as well as daily driving and can say that they hook up amazingly! In wet conditions, I am able to drive with extreme confidence. These tires keep me planted and eliminate the need to heavily reduce my speed like on stock tires. The ride quality is very fair for the size. These tires ride only about 15% rougher than 17" stock Michelin tires. They are much quieter than expected! These tires are Y rated, so they can take any speed a mustang can throw at it. Huge upgrade from the common 115/130 mph rated tires. CONS: These tires don't come with any recommended PSI, but the correct air pressure from ford for this size tire/rim is 32 psi. These tires also seem to wear a bit more quickly than general all-seasons. The treads are not the most aggressive I've seen, but seem to serve their purpose quite well. OVERALL: 5/5 If you're in the market for this tire size, consider these tires over the competition. They are slightly more costly, but make up for that with terrific performance and stability.

I have had these on for a few days now and strangely as it is went threw a rainy day very good! I'm surprised how good these tires are and how great of traction they get. If your looking for a great deal this is the place to get them. I could not find any place online or local that could beat this deal.

    Nice Tires!

    Bought these tires mounted on my new rims. These tires are for the summer only. They are nice and wide, filling the wheel wells up nicely. Only time will tell regarding wear, but traction does seem to be quite good when the roads are wet. Dry traction is also pretty good! These tires are a good value.

    Rides nice, traction... meh

    Affordable, quiet ride, good balance, good highway feel. Not as much grip as the 285/40-18 F1's they replaced, much easier to spin and they make a lot more noise when you do burn them. Happy enough, but likely won't use for replacement after these wear out.

    Review from Sumitomo High Performance HTR Z III Tire - 235/55R17 (79-18 All)

    These tires are the best

    Excellent tires, great ride,great handling ,no road noise. In wet and dry weather great traction, assuming I get the usual 20 to 30 thousand miles I would purchase these tires again. Highly recommend these tires to any other Mustang GT owners.

    Review from Sumitomo High Performance HTR Z III Tire - 245/45R19 (05-18 All)

    AMAZING TIRES!!! Way better than advertised...

    I purchased a set of these tires paired with American Muscle's 19" Charcoal AMR Wheels. I am amazed at the nice race car look and feel that these tires bring to my mustang. Amazing traction, better control of my car, and a noticeable smooth ride are a few of the perks. I reccomend this tire for anybody looking for a safe, high quality product that doesn't break the bank.

    Review from Sumitomo High Performance HTR Z III Tire - 255/35R20 (05-18 All)

    These tires perform and look great

    I purchased a set of HTRZ III tires from my 05 Mustang. They perform great in all weather conditions, while providing a smooth quiet ride. I have had tires with a more aggressive tread design, but they were all very loud compared to the HTRZ III. The quiet ride clearly makes up for the less aggressive tread pattern. I am very happy with the overall look of the tires. Their low profile and width give my car the aggressive stance of a high performance Mustang.
