    Ultra Summer Performance. The Sumitomo High Performance HTR Z offers amazing performance in the summer for any Mustang. Utilizing a unique, directional tread pattern and innovative stability features, the HTR Z is perfectly at home on the track or the street.

    Race-Inspired Tread. The HTR Z gets its unparalleled grip from its directional tread pattern, which incorporates independent intermediate blocks and a continuous center rib to enhance dry grip and stability in the corners. Four circumferential grooves remove water from the contact patch to give constant grip and to resist hydroplaning.

    Summer Compound and Strength. The HTR Z uses a softer, stickier compound to enhance traction in the warm months. Spirally wrapped Jointless nylon bands enhance high-speed durability and minimize weight to improve ride uniformity and acceleration. 

    Application. The Sumitomo High Performance HTR Z Tire is specifically designed as a track and street tire for any Ford Mustang.

    NOTE: This is a high-performance tire intended for use during summer months or warm temperatures only. Use during cold weather will greatly reduce performance, traction and handling, and greatly increase stopping distance. If using this tire in a drag or track environment during cold weather, we strongly recommend performing a pre-run burnout to nominalize the tread compound's temperature.

    Longevity compared to Nitto555's Hello, I'm looking at a set of new rear tires for my 2004 GT, I drive about 100miles a day and the tires lasting is rather important to and I currently have Sumi 315/35/17's on the rear at the moment and have been pretty happy with them. They do have a little road noise to them but not totally sure if thats due to the tread being really wore down at this point, turn the tunes up and no more noise ;) I have had them on the back close to a year and half and have been very pleased, but being that the drivers rear has a plug in it due to a flat many months ago... really needing this corrected and been very lucky with them. But was curious how the Nitto's hold up compared to the Sumi's, I have been very pleased with them thus far so just trying to compare apples to apples. Not sure if the Nittos' are designed with more of a soft compound and not last very long compared to the Sumi's. So just trying to the best bang for the buck... no money tree here!

    • Being that longevity is definitely your main concern and for such a large tire, you will want to stick with the Sumitomo rather than switch to the NT555's. Reason being exactly what you already stated: Nitto's have a softer compound and while they offer a bit more performance over the Sumitomo, they don't last quiet as long in the grand scheme of things. Hope this helped to verify your already accurate thoughts!!

    Will this tire fit on a 17x10.5 rim? Thanks.

    • The Sumitomo High Performance HTR Z Tire - 275/40-17 (99-04 All) will be the smallest size tire you can safely fit on a 17x10.5 wheel.

    Will the 275/40/17 fit on the FRONT factory 17” bullit style rims for an 04 GT?

    • We do not recommend putting 275s on the front due to the size of the tire as this may create clearance issues.

    Hi i have a 2003 gt i put 2 10.5 in rims on the back currently i have 315/35 tires on it but that sizes make the car look to low on the back wat size. Can i put on the back to cover that gap that is showing and to make it look a little higher on the back wats the next size?

    • The next tire size up in height would be a 315/40R17, This tire would be approximately 26.9" tall compared to the 315/35R17's 25.7" in height.

    What is the recommended psi for these?

    • The recommended PSI is going to be located inside of your door jam. It is highly recommended to go by that for the correct PSI recommendation.

      Very Dissapointed.

      Poor wet traction, poor dry traction, poor lifespan. I've never gotten close to so few miles out of a tire in my life. Shocking really, but a lesson learned.
