      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!

      Application. The Sumitomo High Performance HTR Z III Tire is designed for use on 1979-2020 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.

        came broken

        The part which the tire comes in contact with the wheel had a chunk missing when I got it and I noticed it a bit too late so I guess I’m gonna just take the loss also I’ve had these tires before they don’t last very long even just driving normally and not much grip

        Wishes and buts...

        I purchased a set of these tires 255/35/20 with the ASA GT 14 wheel....on my 2016 S550 GT, mt-82,355 gear... I have the CandL cold air intake and 93 octane race tune.... these tires while offering good wear durability and low noise are not wide enough for the traction needed. 75°- 80°daily temperatures for a week..2500-3000 RPM launch results in 50ft-60ft wheel spin,shift into 2nd? wheelspin, shift into 3rd tire chirp.. This is a great tire for the price if non aggressively driven...but if you expect to get the reported 0-60 and 1/4 mile times Ford says the 5.0 is capable of this tire will not get the job done.

        Nice Tires

        I really have no complaints on these Tires. I ordered a set for my 07 Mustang and as far as traction they have surprised me on the amount of grip and how they hug the road. I would recommend these to anyone looking for a quality tire at a reasonable price.

      5 Top Rated Questions

      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?

      • 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 r19/9.5 wheel and want to know can I fit a 255/40r19 without that stretched look on all four corners of my 2015 mustang? I guess lowering will be next...and what is the N2 service if I'm just buying tires?

      • A 255/40R19 Sumitomo High Performance HTR Z III Tire will fit on wheels ranging from 8.5" wide to 10" wide, with 9 being the "ideal" width. These should fit very well on your 19x9.5" wheels, and still allow you to lower your Mustang. If ordering wheels and tires together, we offer free mounting and balancing with Nitrogen or compressed air. Tires ordered by themselves are not able to take advantage of this.
