Review & Install Video

Sumitomo's HTR Z III series tire is an ultra high performance summer tire. The aggressively designed 255/35-20 delivers extraordinary performance in either wet or dry conditions, on and off the track.

Uncompromising traction and handling. The HTR ZIII's five rib asymmetric tread design pattern merges cornering with straight line stability. Siped tie-bars reinforce block rigidity for control and enhance wet traction.

Excellent anti-hydroplaning characteristics. Long lateral grooves evacuate water from the center of the footprint. Four straight, wide grooves further heighten drainage for improved wet performance. A 3-D wave wall increases drainage capabilities and reinforces center rib stability.

Smooth ride; minimal road noise. In addition to outstanding performance, the 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!

Real world durability. Rigid, wide steel belts, high tension casing plies, and advanced silica tread compound construction means these tires are designed to last.

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.

Best Fit: 20 x 8.5 Inch 2005+ Wheels

  • Y-speed rating for true high-performance vehicles
  • Direct replacement sizing for premium performance vehicles
  • True performance upgrade sizing for performance segment vehicles like the Mustang

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.

    Oredered for a spare tire

    Tire arrived mounted to the 20x8.5 Magnetic wheel that I ordered with it. Tire looks good and gets good reviews. So lets hope I dont need it but if I do I have a real spare as opposed to the wonderful Mobility Kit which is a joke. American Muscle the service, product and price is great. I'm sold. And happy to have a real spare tire, I also purchase a compact 2 ton floor jack that I store in the trunk for use if I have a flat. Thanks

    Sumitomo High Performance HTR Z III on 2013 5.0 Turbo

    What a great tire for the stang. I have a 2013 5.0 with a hellion single turbo kit. I was having a hard time hooking up with my stock tires. Man what a improvement to both grip and ride feel. I no longer loose traction like before. I went with 20 inch American Muscle rims and offset tires 285 in the rear. Wont be disappointed for the price few will rival these tires.

    GREAT TIRE all around!

    I went with these because research showed they would have a good tread life compared to the Nitto's. I have not like either set of Perelli's that came with my Mustangs so gave these a try. They are great traction in dry weather, very good traction in wet weather... I never really slip unless heavy on accelerator in heavy rain. I even took these to the track and had very good traction on 1/4 mile runs. Very please with these tires especially for the price. Got the 20" AMR's with them as well and they are really good looking wheels

    So glad I went with 20" rims there not to big at all!!! After awhile I will probably lower it because there is still alittle bit if a wheel gap. All in all the wheels are amazing and changed the whole look of my car. People have mistaked it thinking it was a gt500 ! Thanks AMR !

    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.

    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.
