HTR Z. The HTR Z Series is Sumitomo's Ultra High Performance summer tire. The aggressively designed 275/40-17 tire delivers confident performance in either wet or dry conditions, both on and off the track.

Superb Wet Grip & Traction. Sumitomo HTR Z Performance Tires feature a directional offset V tread pattern that literally plows water out of the way.

Excellent Anti-hydroplaning. Four, deep, wide circumferential tread grooves provide excellent anti-hydroplaning performance.

Enhanced Steering Response. Large angular shoulder blocks provide enhanced steering response and overall dry grip. A solid center rib helps deliver directional stability even in the most heavily grooved highways.

Sidewall Stiffeners. Improved steering response and overall handling without sacrificing ride comfort. In addition to excellent performance, the HTR Z series tires deliver a smooth ride with minimal road noise.

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: 17 x 9 Inch 1999 to 2004 Wheels

  • Excellent handling characteristics at high speeds, and superb wet and dry traction
  • Triple Tread Radius Provides optimum performance footprint for maximum traction
  • Center Rib Enhances straight-line stability

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.

New rubber.

Bought these to go with the Cobra Deep Dish wheels. The handling was quite improved over the previous tires, no more under-steer! Traction is greatly improved, and they feel fine in the wet. Only slight

    Sumitomo HTR Z tires

    March 07, 2010

    I am very pleased with the Sumitomo HTR Z tires that I recently purchased. I put the 275/40-17 in the rear on a 17x9 Antracite wheel and they look great. They are about appare to be about 1" wider then the 245/45-17 stock tires that I have on the front giving a very aggressive staggered look. The Mustang stock center caps do fit a bit loose on the aftermarket Wheels.

    New rubber.

    April 25, 2010

    Bought these to go with the Cobra Deep Dish wheels. The handling was quite improved over the previous tires, no more under-steer! Traction is greatly improved, and they feel fine in the wet. Only slight problem is they rub on the front sway bar at full lock. A set of 1/4" spacers might be in order.... Would happily buy these tires again. Thanks AM! Matthew

    Excellent bang for the buck

    This is the third set of these tires I have purchased from American Muscle. I average around 50,000 miles each set of tires depending on how hard I am on them. The only down side is after around 50% of the tire wear they start to lose traction, but still not bad. I do recommend these tires. The 315/35 17 and the 275/35 17 combination looks awesome on the 03 Mustang.

    Well worth the money, by a long shot!

    January 29, 2012

    So I had the same size tires on back that I ordered, unfortunately mine looked like slicks with some wires showing, definitely time for new ones especially with winter around the corner, not to mention a mustang is not the greatest car for winter. So I looked around at local tire shops n they wanted anywhere from $340-450 some even $500 for tires that aren't even as good as the ones I purchased from AM. So I ordered tires from AM payed $260 for the tires and $39 to mount and balance them, overall $300 bucks. The sumitomo HTR Z tires are excellent tires awesome grip dry/wet even good in the snow. Im very happy and impressed with the quality and look of the tire, and the grip is amazing. When I have to get tires again I will definitely make the same purchase, just in a different size so I can widen my back rims, also the free shipping makes this choice much easier to make. Thanks AM for helping me make my mustang the car that gets the looks and compliments and the speed to stand out in the pack. 96 mustang gt your very well n pleased customer who will always come back again n again, Nick Vance.

    These are great tires. They grip well, even in rainy conditions. The only problem I've noticed is that it seems like they're a bit "noisier", but I can't confirm that, since I didn't pay attention to the stock tires.
