  • Uncompromising Traction and Handling
  • Excellent Anti-Hydroplaning Characteristics
  • Smooth Ride; Minimal Road Noise
  • Unique Flanged Lip Protects Rims
Sumitomo's HTR Z II series tire is an ultra high performance summer tire. The aggressively designed 275/40ZR17 delivers extraordinary performance in either wet or dry conditions, on and off the track.

Uncompromising traction and handling. The HTR ZII'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 right 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 road grip in adverse weather conditions.

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

Unique flanged lip protects rims. The HTR Z II Series Tires also feature a unique flanged lip on the lower sidewall that helps protect your expensive rims 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.

Best Fit: 17 x 9 Inch 1999 to 2004 Wheels

  • Wide block shoulder stabilizers strengthen shoulders for maximum dry grip and greater, more predictable, steering response for cornering control.
  • Full-width, high density steel belts promote stable, predictable handling, smooth ride, even tread wear, and superb uniformity .
  • PSP Technology optimizes overall casing durability throughout the life of the tire

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.

Will these work on a 17x10.5 in wheel? the width is wide enough but it says they fit 9 in wheels best.


  • A 9" wheel is just our recommendation for someone who is not sure which wheel they should go with. You can certainly mount these on a 10.5" wheel.

  • The Sumitomo High Performance HTR Z II Tire - 275/40-17 (99-04 All) will not fit on a 17x8 wheel. The biggest size that would fit on a 17x8 wheel would be a 255.

    I had the htrz sumi"s on the rear and did'nt really like them, traction was poor in the rain. but with these its awesome if i get caught out in the rain with the stang. price is good and would recomend to anyone who has 17x9 wheels. My setup is 17x9 all around, 275/40/17 in rear and 255/40/17 up front. only thing i say is even my 255's rub in the front. (cars lowered 2 inches) so just factor that in if your thinking about putting 275's all around

    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.

    Great bang for your buck. Big for a foxbody.

    Great tires for the money. They look great and they function great. Would buy again in a second. Just FYI, though pretty minimal, 275/40-17 tires take some work to fit on any foxbody, I don't care what anyone says. You will have to flip the quad shocks at a minimum and if you have a notch like me there is a good chance you will have to do some creative bending to keep your tailpipes from touching the tires or throw on 1/4" wheel spacers.

    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.

    Great tire just put the 275/40-17 on all four corners of my Bullitt. Drove in the rain for the first time with the new tires, 1 million times better then the stock gatorbacks, dry traction is great also. It\\\'s a solid tire but still not close to the Nitto 555 if that is the type performance you are looking for. Overall can\\\\\\\'t beat the price at 120 a tire its an absolute steal.

    The Sumitomo tires are great. Have them on all 4 corners of the car andI I've had no problems. You get extra grip, and a smoother ride! Great buy for a cheaper tire and it has a nice triangular design for the tread to reduce hydroplaned. GREAT IN THE RAIN!
