Review & Install Video

Sumitomo's HTR Z III series tire is an ultra high performance summer tire. The aggressively designed 285/30-20 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 10 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.

    Great tire for the price

    So far I have been very happy with these tires. I was not looking for an all out performance tire, just something for summer on my daily driver. The ride quality is surprisingly good considering the aspect ratio. So far they are very quiet as well. I have them on 10" wide AMR wheels and to me they look a little small, not sure if it needs more sidewall or to be a little wider. Wet traction leaves something to be desired compared to the factory all-season tires, but I guess that is to be expected on a high performance summer only tire. All an all you would have a very hard time beating them for the price.

    Great Tire

    Bought these with the 20' AMR package. Very good ride. Tread pattern is not as aggressive as the Nittos, but I don't notice because of the lower price! You really can't beat a staggered 20' staggered fitment at 1,489.00 for wheels and tires. Free shipping! UPS sucks though. Wish they switched to FedEx.

    Don't make the same mistake I made

    If you are looking for a performance tire, don't look here, this tire has good grip, that is why I gave it 2 stars instead of 1, but that is where the performance ends! The sidewalls are sooooooo soft, they put all the body roll back into my custom suspension. There is a reason they are cheaper!! Put out the extra money for a real performance tire! If you want a tire that has good grip but rides like a stock tire then this is for you, but if you want to feel the road and no body roll then look somewhere else!!

    Above your standard tire!

    I have these on my five stars. WOW, it says that its a summer tire... but its 32 degree here in STL and it handle like a pro on the streets! This is normal driving, not racing! It hook up so WELL and taking courners its like a video game. I guess the old saying is true..."Wide-er is better". Of course this isn't the tire if you have tons of snow on the ground.WIth these tires, you will make people think twice about steping next to you. ... so I can just imagine how it will handle when it gets warmer. The looks of this huge wide tire... it makes people wonder what you have under the hood. In my personal opinion, you will NOT feel bad about buying these tires!

    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.

    I'm not a racer and I've never taken to the track. This tire suites my needs as an enthusiastic daily driver. Good grip, solid feel, plus non-directional so rotating is an added bonus for those that run off-set set-ups. If you're a hardcore racer then you might wanna spend the extra coin for a superior tire, but if you want good performance for a daily driver, give these a try.

    Sumitomo 285/30/20 review

    These are a great looking tire that have improved the traction on my 06 GT immensely. The car doesn't go out in the rain so I can say about how they track on a wet surface but for a dry/summer tire I can't complain.

    20 inch Sumitomo tire and wheel package.

    Tires are low noise for an aggressive tire tread and handle well. The black Bullitt deep dish wheels are visually striking and added a aggressive stance to my stang.

    Sumitomo Review

    So far, I am truly enjoying the tires. I like the fact they are a non-directional tire so I can still rotate my tires. They look really good on a 20x10 rim. I have received so many compliments on my 2011 V6 Mustang since I made this purchase. Their a good tire for the price. I would definitely recommend them.

    Great tires for a great price

    When you go to a 20 inch rim selection is limited however I am pleasantly surprised with how these tires perform even in colder weather I have still had plenty of grip and the car felt solid mind you I just got these tires and have not put many miles on them but I will say the car is much more responsive and grips the road very nicely the tread is also more All Season than any other tires that American muscle sells for 20 inch rim and that is the main reason I bought them

    great tire

    great looking and feeling tire they ride very smooth and handel well in both condtions rain/shine. i have hade these tires on for about a week and they are very underated in my mind they have the ride comfort of a high dollar wheel as well as a great look dont let the 30 throw you off because the diffrence in that and a 35 is mabey a millimeter difference i bought the set along with the 255 up front and could not be more impressed i thought the side wall would be to small but is actual perfect.

    Never thought. I would buy rims and tires online lol

    Buying from these guys I was very happy with the shipping and product, but I never bought anything with this high of a dollar amount. Rims came in took a little over a week, found out I was missing a center cap, called them up the same day and shipped out the same day free of charge, got the new one in two days later and slapped it on and put the wheels on and I was shocked, I had an 07 and I knew these rims look good on those s197. I was a be worried about putting them on the 2011 body style... But I made the right choice with theses rims. it really makes the car look tough. Overal service, shipping, getting my rims, tire, lug nuts, air and balanced all at one place was a great buy.
