    Hey, everybody, I'm Justin with AmericanMuscle.com, and welcome to my detailed breakdown of the Sumitomo HTR Z III tire available in sizes to fit you '94 to '15 Mustang. So the HTR Z III is the third generation in Sumitomo's high technology radial lineup. And as you might expect, guys, it's gonna be the most capable. Now, Sumitomo categorizes this thing as a max performance summer tire, carries a UTQG rating of 300 for tread wear, the max possible for traction which is a double A, and a single A for temperature. Since these are a max performance summer tire, I'd be weary of using this rubber in temperatures below 45 degrees if you plan on doing some spirited driving as they do tend to harden up, and they will, of course, lose some traction. Now, can you still use these things in the cold weather? Absolutely. In fact, I had a set of summer tires on my own GT. I drive it all year long here in the northeast. You just have to be smart about it. Grip certainly suffers and traction is really hard to come by until you get some heat in the tires. But again, if you do plan on driving in the cold weather conditions, just be safe and use your head. Getting in to the sizing here with the HTR Z III, we'll find these things available in a ton of different sizing options, including 17, 18, 19, and 20-inch diameters, giving you the ability to run these things on your SN95, your S197, or even your brand new S550. Because of this, you will find these tires available in a lot of our pre-assembled wheel and tire kits here at American Muscle. So be sure to check those out if you happen to be shopping for wheels and tires at the same time. It'll definitely make life a lot easier.Diving a little deeper into the Sumitomo, the HTR Z III, you are gonna find more of a traditional tread pattern, which is certainly a departure from the radical tread pattern Sumitomo used with the HTR Z II. And you are gonna find a lot of new tech into the tread itself. They used an asymmetrical design here which is gonna help both your straight line stability in addition to your cornering performance. Getting into the wet performance, guys, you will notice of course these four really wide deep grooves here, and that's gonna do a great job of basically exiting all water from the tires footprint, pumping out your wet performance. Now, an interesting little fact here with the HTR Z III, Sumitomo claims that this extra ribbing here at the inside shoulder block is really gonna help with the wear characteristics of this tire especially on cars with independent rear suspensions, hello, S550s, in addition to cars running a little negative camber. Of course, that's for all you guys out there with lowered Mustangs. It is worth pointing out, guys, that the HTR Z III and all Sumitomo tires, for that matter, are covered by a limited workmanship and materials warranty. And basically, what that means is that this thing is gonna be covered for pretty much the life of the tire from any manufacturing defects, but unfortunately, won't cover any road hazards or anything like that. As always, guys, if I haven't answered every single one of your questions about the HTR Z III, and you do wanna talk more tire tech with a Mustang expert, reach out anytime. They'll be more than happy to get you set up with the right tires for your setup. So if you guys are looking for one of the best values on the market today in regards to dry performance, excellent road manners, and a very competitive price, then be sure to check out a set of HTR Z IIIs for your Mustang here at AmericanMuscle.com.

    Description

    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 1979-2024 Mustangs.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.
