    HTR Z II Summer Tire. The Sumitomo High Performance HTR Z II Series Tire is an ultra high performance summer tire. Its aggressive extra wide, arched tread blocks deliver extraordinary performance in either wet or dry conditions, both on and off the track.

    Uncompromising Traction and Handling. The HTR Z II's extra wide, arched tread blocks deliver uncompromising racing slick-like dry traction and handling. Dual steel belts with spirally-wrapped Jointless Nylon Band reinforcements deliver high speed stamina and predictable handling, while still minimizing weight and superb uniformity. Single Strand Beads help improve wheel fit and retain rigidity under high stress cornering.

    Excellent Anti-Hydroplaning Characteristics. Multi Directional Water Channels push water to the sides and away from the center, providing excellent hydroplaning resistance and enhanced road grip in adverse weather conditions.

    Smooth Ride w/ Minimal Road Noise. In addition to outstanding performance, the HTR Z II Series Tire delivers 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 stereo system!

    Unique Flanged Lip for Wheel Protection. The HTR Z II Series Tire also features a unique flanged lip on the lower sidewall, which helps protect your expensive wheels from curb damage while parallel parking.

    5 Year Warranty. This Sumitomo 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. This Sumitomo High Performance HTR Z II Tire is designed for use on any 1979-2018 Ford Mustang model. Please select your proper tire sizing from the options above.

    NOTE: This is an ultra high performance summer specific compound and tread tire. Use during the summer and warm temperature months will result in superior traction over & all-season tires. Use during the winter months or in cold temperatures significantly reduces traction and increases stopping distance, as the compound becomes less sticky.

    I'm shopping tires, what's the width difference in 265/35/18 and 315/35/18?

    Chaz73

    • The width of a tire is actually the first number listed in the tire sizing: ie. for the 265/35-18, the width is 265mm and for 315/35-18, the width is 315mm. Hope this helps!

    I want to put the free nitrogen in my tires ok. When the tires are low on nitigen can I mix that nitrogen with air . Do I have to fill it up with nitrogen again

    Reinel

    • You can refill with air without causing any harm, but it will ultimately defeat the purpose and eliminate the benefits of having the nitrogen fill. I'd check your local area to see if there are any places to fill up with nitrogen. Usually some tire shops and similar places may have it available.

    Will the 255/40/17 fit on a 8" wheel?

    SteveM

    • Unfortunately a 255/40R17 tire will only fit a wheel that is between 8.5" and 10". For an 8" wheel, we recommend a 245/45/R17.

    Hi this is Tomas from Mexico city, could you tell me if this kind of tire works for my Wheels, if the size is 10 in rear and 9 in front?. Also what is the price in 275/40 rear and 255/45 front, same drawing. Thanks a lot

    TomasA

    • Hi Tomas! On a 10" wide wheel you are able to fit up to a 305 tire size but we would recommend sticking with a 275 or 285 and for the 9in wide wheel we would recommend a 255 tire up front but the tire sizes would depend on the year and model Mustang that you have. Unfortunately, without that information, we are not able to advise on what would be best for your build. If you can, please reach out to us by phone or email so we can discuss what options would be best as well as get the proper pricing for the tires we recommend.

    I’m currently sporting 235/50R18 on a 2007 Mustang GT premium. I do not see an option for that size for your Sumitomo High Performance HTR Z II. Is there an alternative size I can use?

      Lasted over 30,000 miles

      I bought a full set of tires in 2013 and since put exactly 30,000 miles on them. Currently all 4 tires are in the Yellow territory when I check them with my tire depth gauge tester and will soon need to be replaced. Overall, I have not experienced any issues with them. They grip very well when it's warm outside but you have to be super careful when it's raining or slippery. I'll most likely but the same ones again soon.

      Review from Sumitomo High Performance HTR Z II Tire - 275/40R17 (79-18 All)

      Great Value

      So far the tires seem to perform well. They are a bit loud as others have said, but just turn the music up or get some louder exhaust and you will be fine. The noise would not deter me from buying them again. I believe these may be the best bang for the buck tires made. I have only put about 1K of miles on them so far. They also look good and aggressive on the car. Try traction is super good. Wet traction is not great, but no better or worse than my all seasons that were on the car previously

      V6 Mustang tire upgrade

      Great braking and handling so far for my 2005 v6 Mustang. I was concerned about correct speed due to upgrading to a 17" tire vs the stock 16 but like the AM tech said, I would not see a big difference. My speedo now says 57 and gps says 55. Great looking tire, very satisfied.
