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.

I have a set of Saleen 18x9 I have 245/35 on there now. How much bigger can I go?

DevanG

  • There are a lot of factors that go with this. Year of car you are running them on, placement of wheel front or back, just to make sure clearance is there to fit them. But for an 18x9 the biggest tire you can safely run that we recommend is 265/35, you could probably squeeze a 275/40 on there but for the most part 265/35 would work great for you!

    These tires are great for daily driving and provide great traction dry and wet. The only bad thing about the is they dont hold up to th abuse of autocross racing. Besides autocross these tires are a great buy. 15000 to 25000 miles on them depending on how you drive.

    Review from Sumitomo High Performance HTR Z II Tire - 275/35R18 (79-18 All)

    Cheap tire, BEWARE

    These tires might look good on your stang, but they are not worth it. I had my set on mine for about a year & about 20,000 miles. They would get a flat spot after sitting for a few days and it took ~10-15 miles to work itself out. They also got these dry-rot type cracks all over the outside edge. I finally had to take them off the car after one of the tires developed huge bubbles in the sidewall. Tried to get a new set, but was informed that this problem wasn't covered under the manufacturer warrenty due to the use of tire shine products. I never once said I used those products in any of my emails, so how they assumed that I did I have no idea. If I could do it all over again, I would have definately spent the extra $$ and bought the Nitto tires instead.

    HTRZ II Tires

    Under spirited driving conditions these tires just simply dont cut it. They look great, ride comfort is nice, and they arent noisy. However after only a couple thousand miles they lose what little grip they had, wear terribly, arent very responsive, and wet weather driving / hydroplaining resistance is terrible. Wouldnt buy them again, spend the extra $50 on a set of REAL tires.

    The price for wheel and tires mounted and balanced were too good to pass up.The wheels and tires came mounted and balanced sooner then anticipated. Within 30 minutes they were on the car. After 5k miles theres no vibrations at all and with the tires now being broken in they perform far beyond my expectation.

    Amazing Dry Traction! Best Cornering Tire!

    I purchased 275 40 18 HTR Z II about 3 weeks ago I have been pushing thes tires in the corners to test how good they are. I'm able to take corners that I know the rearend would have kicked out on me with my Perelli tires that where brand new when I purchased my mustang with only 25,000 Miles on it. I have found that the wet traction is good but I did slid once on a wet painted line when I was driving to fast and had to stop fast. So tried several 50 mph hard stop in pouring down rain and the have not slid at all and was able to stop just as fast as in the dry. these tire have the best cornering grip of any tire have ever driven on

    Great DD tires

    Bought these to wrap in my 18x10 Chrome bullits in. Are they the greatest tire ? no, Are they a great tire for the price ? definitely ! For straight up street cars and daily drivers these tires really deliver. The ups are the price , the handle compared to factory are great , they look really nice. The down side is that they spin alot with 3.7'3's , must watch the hydroplaning. I recommend these for a budget minded street driver.
