I have a few questions for you. I know this is a bad idea....blah blah blah, but I want some of the opinions of the people who actually have this set-up. I am curious to why you just didn't get a 11" wide wheel in the first place? What kinds of difficulties do you have with this set-up? How long will the tires typically last(Nittos)? What psi do you run them at? Do you use them for the track only or all the time? How did you convince someone to mount them? Thanks a lot!

FYI Stock 17" wheels are 9" not 9.5"

I have Enkei Win wheels that are 17X9.5 all around. I have HTRZ 275/40/17's in front and 315's in back. I wanted to go with the 315 in back but at the time, I could not find a 17x11 rear wheel that I liked that I could afford. I called Enkei and Sumitomo both about the 315 on a 9.5 inch wheel and they both said that it would not be a problem. The technician at Enkei also said that there are many people that put the 315 on a 9.5 inch wide wheel and that it would not cause any problems. I asked him about the suggested wheel size being 10.5 inches to 11 inches. He stated that they do suggest that size for the 315 but that as far as causing any problems that would lead to tire failure, he did not think that it was an issue. I like it, it gives the tire a little bit of a buldge and fills out the wheel well without sticking out. To date, I have not had any problems with rubbing or anything. I would love to have the rims widened but being that they don't make my wheels anymore, I would be afraid that if one was damages I would be SOL. Besides, I haven't been able to find someone that could do it. I also have heard that putting the 315 on a 9.5 inch wheel causes you to lose traction because the contact patch is different. I get good traction with my 315's and I think that the contact patch is about the same as if it was on an 11 inch wide wheel.

so we're talking street tires not drag radials? just curious cause im looking at new rims and have heard some horror stories with drag radials (required on street) and the sidewall softness

Ive put probably 20k miles on my car with 315s on a stock rim and I havent had a single problem, ive driven the car hard as ****, high speeds, turns etc....they feel like a stock tire, I dont think they are unsafe at all.

Do you have any pics of that set up? I've been thinking about putting some 315 555Rs on my LGM (enkie) wheels and would like to see how 315s would look on them. Nitto's tires seem to be undersized but then again the soft side wall at 22 psi has me concerned. I'm still up in the air about it.

I had the same thing on my Enkei Win wheels. They looked good and hooked up as well as the 275/40's I had on before. Now that I have some LGM G2 wheels for my '69 Firebird, I think I'm gonna put the same 315's on the back as well. Since I can't afford the Fikse 18x12's for my 335/35 Michelins sitting in the garage right now

I have 315 Nitto DR's on my 17x9 '03 Cobra wheels. 315 Nittos are more like a 285 or a 295 in reality. They fit just fine.

Not sure if that's what you were looking for or not. I have pics if you need to take a peek.

Well I did alot of searching around on the net this afternoon and I've deffinatly been convinced that there will be no problem running the Nitto 315s on my 9.5" wheels.

Unit213: If you do have a pic of the side walls I would be intrested in that (or just a nice *** shot). I can't imagine that they'll bulge to much. Hell, my Nitto 275s look undersized on my wheels now.


BTW: Are you guys still running these at a low psi without problems?

I am sure there is some danger with this combo, but I really doubt it is anything to worry about. I saw some Nitto 315's on a 17x11 ZR1 the other day and with those if you get to close to a curb... bye bye nice wheel finish. The extra "bulge" that 315's on a 9.5" wheel have will probably offer a little bit of extra protection.

Unit...sent you PM

I emailed these pics to Ferocity already. Here they are for those of you who are interested.

315 Nitto DR's on 17x9's. I run them at 26psi on the street and 18psi at the track. There are TONS of '03 Cobra guys running this same combo. I'm not sure if it'll fit in the wheel well of an fbody or not, but I know for a fact they'll fit on a 9" wheel with ZERO issues.

Yeah, I'll take the "WHEEL MANUFACTURER'S" advice . . . no they don't want to sell wheels . . . Lets see . . . Firestone recommends atleast 30 psi in their tires for the Exploder . . . Ford recomends less than 28 psi. . . tires disintegrate . . trucks roll over . . . people die . . . who's wrong? Ford, or Firestone?

NOBODY who MAKES tires recommends a 315 on a 9.5" wide wheel . . .

Kinda resurecting this thread but I put on the 315s on my 9.5" wheels and took some pics. They bulge alittle but a good friend of the family who has owned a tire shop for 30 years said that they will be fine even at 20 psi after he mounted them. They stick a hell of alot better than my 555R 275s, it's nice to be able to spray in first gear now.

Do you have any rubbing issues or anything with the 315s? Also you are talking about the 315-35-17 Nittos correct? thanks

It looks like I will have to roll the inner feder lip since my wheels have so much offset. They havn't hit yet but it looks like they will going over nasty bumps. And yes they are 315/35/17s.

XSTA Z 28, I really don't think that Enkei and Sumitomo both are going to lie to me just to sell a product knowing that it would be unsafe. Hey, maybe they contacted each other and conspired to sell me that wheel and tire combo. If people don't want to put 315's ona 9.5 inch wide rim, then don't. I wouldn't be out doing any road racing with my combo but it serves my purpose, a garage baby that is taken to car shows, cruise in's and and is only driven 300-500 miles a year. I check the tire pressure quite often to make sure that I will not have any problems and so far, I have not. I guess when I start hearing about people with 315's on 9.5 inch rims rolling their cars over and getting killed, I will start to worry and do something about it, but so far, I have not heard of anything like that. Also, the large police department that I work for went to Firestone Firehawks on all of our patrol cars as the usual "low bid" and every officer that I have talked to thinks that they are an all around better tire than the Goodyears that they replaced. No rollover's due to those tires yet either.
