    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.

    5 Top Rated Questions

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

    • 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

    • 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.

    • Due to its nature as a performance tire, we typically see between 25,000 and 35,000 miles tread life depending on driving conditions and driving type.

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

    • 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.

      Tire combo

      The tires are very satisfactory. Ordered the staggered 95 cobra R combo. Love the wheels very much, They are super shiny. The front tires match the rims perfect, The back tires are to narrow for the wheel width. The sidewalls seem to flare out to meet the rims and look weird. This is not the tires fault, just to narrow for the rims. They probably should be wider tires on the rear but the tire itself is good.

      Fair priced tire

      overall I feel they are good tires, on my 07 GT they seem rough riding, especially when its cold out. In the rain forget it they just spin in every gear. on hot dry pavement, I really like them, they stick good and wear good.

      Symptoms HTR Z II Tires-New Sneakers for my girl!

      These tires are meant for high performance at speeds over 100mph. I can't say I've never tested "the performance" at that speed, but they provide a smooth, tight around the corners, ride. Do I "need" this tire on my car? No. Do I like and want this tire on my car? YES You get what you pay for. 5 Stars from me!

      I purchased these tires for my '03 GT Convertible. I'm amazed at how well they perform and grip. I live in Florida and it rains quite often and they grip extremely well in wet conditions too. I'm very impressed with the performance without the high price.
