These tires are cheap as hell.

Anyone have any experience with them? Complaints? I might go with them just to try them out before I get BFGs later on down the road. Unless of course someone has had a horrible experience with them. At least I won't feel bad if they get chewed up. ;)

I have these on my Z in a 255/50/16. They're good tires, depending on what you plan to do with them. I autocross on mine, and for that reason, I hate them. They have soft sidewalls, and too much tread depth. Which causes tread skwirm and throws the car off balance in tight transitions. But if you're just going to drive them on the street, they're a great tire for the money. They're awesome in the rain, have good grip, and last a good while if driven conservativly. I haven't been to the drag strip with them yet, but with the soft sidewalls, and good grip, I imagine they would do pretty well for a street tire.

Well I'm definitely expecting no autocross tire out of it. BUT if they totally squirm out everytime you do something more than putt around then that's not gonna be too good for me either. :)

On occasion I like to do a little bit of spirited driving up a mountain backroad with some nice scenery. I don't get crazy at all, but I still don't want to come out of a S turn and end up wrapped around a tree because the tires did something ridiculous like get all unsettled at 30mph. :blah:

What do you think?

I've got them and for the price, you can't beat them.

They'll be just fine for that. I didn't mean to make them sound scary. It's just in autocross conditions, (which is 10x's harder than even spirited street driving), they don't perform as well as some other brand tires. But there's something to be said about those better performing tires, that is they aren't near as streetable. They wander all over the road, and make a ton of noise. The Sumitomos are a nice compromise of ultra high performance and streetability. Get them. You won't be disappointed.

Okay cool. :cool: Thanks a lot man, I think I just might try them out then.

I have them on the back of my car(315/35) and I have no complaints. I cant hear how noisy they are or are not b/c of my exhaust. But they do hook pretty good and last a good while. And when you chirp 2nd, these dont chirp they bark.

I have had them now for over 4yrs and they are the best tires I have used on my 87 IROC-Z. I would purchase them again. Godd grip in the dry & rain with good handling. All you can ask for. Note: Summitomo is the parent company of Goodyear and do their design work now. The Tread design on HTR-ZII tire is just now showing up on the Goodyears with a higher price.

I have them, no complaints.

i had them for 2 months the guy said becuase i went to a 315 35 17 my traction would improve.i hated those tires did nothing for my traction i went from a 275 40 17 to a 315 35 17 first and second was useless i went back to american tires told them i wasted my money they let me trade them in for bfg ta drags changed my 0 to 60 1 full second

i have them and love em...you can't beat em for the price.

...let me trade them in for bfg ta drags changed my 0 to 60 1 full second

not tryin to call u out or anything but, you really can't compare street tires to drag radials when it comes to traction, of course the drags are going to hook better...

he asked i answerd trying to tell him the honest truth and save him money. just buy the cheapest tire possible if your thinkng about those tires. whats the piont you were on right track just do bfgs can always do just regular bfg ta if you want more wear.mark my words you will regret those tires.if you r car is slow or stock maybe you will like them but on my car even the drag radials arnt enough in first 2nd hooks awsome.good luck

Some people do use their cars as a daily driver and can't be using Drag radial. :rolleyes:

It doesn't matter if you have a 300 RWHP car or a 700 RWHP car, if he wants a good street tire, then that is what the Sumitomos are for, not drag racing. Common sense should tell you that ANY street tire is not going to give you good 60' and quarter mile times. :rolleyes: :rolleyes:

i dont know why you guys are atacking me no crap theres a diffrence. thats what im saying he says in his post bfgs he is thinking about them.and thier are good street tires and summitomo arent one of them just buy visa than its better and cheaper i dont understand how you can say its a good tire?if you want a rock hard rubber tire with little to no traction that is the tire for you!!!maybe if you r car is automatic, stock horse power v6 it wont spin to bad but on my car these tires did nothing. i will stand buy my statement its a fact!!!!!hey bro good luck dont waste your money you wont be happy with those tires.spend a little more i know people runing pilot street tires and bfg t/a thier traction is good there not drags.i have bfg drags was a little surprised about amount of tread i havent tried m/t but guessing thier better.

I believe that he is talking about BFG street tires, there is no mention of drag radials in his post. :alert: You are comparing apples to oranges and as far as street tires go, the Sumitomo is a pretty good tire for the price. Nobody is comparing them to any top of the line tires, they are a budget tire at a budget price. As far as your car blowing them off, my car made 300 RWHP and 314 RWTQ and they don't get blown off on my car, I get decent traction for a street tire. I find it hard to believe that yours does with as little mods that you have. :rolleyes:

1camaro, is there even such a thing as an "American tire" anymore? lol

My dad just bought a 1996 LT4 vette. I want him to put some Chrome ZR1's with 17x11 in the rear. Would these be a good tire? They are pretty much the only ones I can find that don't cost 300 bucks a piece. He will prolly only put 2,000 miles on the car a year. What do you guys things?

My car is a garage baby and is MAYBE driven about 500 miles a year. That is why I bought the Sumitomo's. I couldn't see any reason in spending $1000.00 plus on tires for a car that is going to sit in the garage nearly all year. I think that they would suit your dads vette just fine.

It's pretty simple, because I don't need nor want drag radials. My car is a street car through and through, I don't take it to the strip, I don't race it. I drive it for recreation and to car shows, that's it. When I get to the point that I want to take it to the strip, I'll put some ET streets on my stock rims or get some drag lites and tires. When my FI engine is done, if the cars puts down 650+ to the tires, I still won't put drag radials on. I really don't feel like having my paint sand blasted and I don't want the hassle of being all over the roadway of it rains on me.

, my car made 300 RWHP and 314 RWTQ and they don't get blown off on my car, I get decent traction for a street tire. I find it hard to believe that yours does with as little mods that you have. :rolleyes:

i see the diffrence now i have 410 gears you have stock gears make a huge diffrence.sounds like a nice car i havent done the shifter yet my friend has one i like the short shifter without bushing,better shifts.

Thats exactly what my dad said. I was just going to have him get NT555 for the front and NT555R in the rear. He just didnt want drag radials because there is no need for them. And im sure he would want to take it up to KC everynow and then to see my sister. When I had my nittos on my mustang I hated them on the highway because they picked up everything. It sucked.
