Will a 315/30x17 fit in the rear of 96 coupe? I just put new wheels on and have the 11" rear rim, the old 285/40x17 tire lookes "rolled in" and the rim sticks out further than the tire. I dont have a lot of clearance now with the 11" wheel from the brake lines, who is running the 315s and did they have any issues?



I was looking at putting the 285s on the front since I am running a 9.5 wheel there now and putting new tires on the back, just want to be sure before I go order them.

If you have 11" rear rims, then you'll want to put 315/35-17 tires on.
As you've noticed, the factory 285/40-17 tires did not fit correctly.

You asked about a 315/30, but not sure if that was a typo or not.
I don't think anybody makes a 315/30 size.

The cars that came with the factory 11" rear wheels (Grand Sport and ZR-1) used the 315/35-17 tire size.

They will stick out a little though. Remember, the ZR-1 was a lot wider body than a regular C4. And the GS used a fender flare to sort cover the tire.

I'll look tonight to see what my 315x??x17 tires are. Not sure if ??=30 or 35
They don't rub on my 92 in the front or in the rear.

Standard size for 11" rear is 315-35/17. They may rub a little bit on the inner fender well (the plastic part) if you are lowered, but not on anything important.

315 35r 17 Kumho tire on 11 inch rim on my 94 stick outside of fender. Tires do not rub on the fender or inner suspension.
Different brands do not have the same dimensions.
My Corvette is stock height.

315x35x17 is what they are.

No rubbing on all 4 corners

Went to all the major tire shops yesterday, nobody had them in stock, those who could order them wanted and arm and leg $325 and up. I can order the Nittos for about 200 bucks each online... then I have to find someone to mount and balance them-all the guys I trust dont want to mount someone else's tires, they will but they then get their arm and leg from you anyway!

Thanks for the info guys!

Tire Rack (www.tirerack.com) has an installer network that works well. They will ship your tires to an authorized installer in your area who will then call you once they arrive & schedule an appt to do the install. Pretty slick system & reasonably priced...check it out.

Yeah, be prepared to dish out major $$$ for 315-series tires. My BFG G-Force T/A KD were like $550, just for the 2 rear tires, and that doesn't include installation! Next time I need a change, I'm just going with the Sumitomo HTR-Z III (or whatever number it is now). They're really cheap, and everything I've read says they're great bang for the buck (i.e. not the best performance, but pretty good, and even more inexpensive)

Tire rack has a close out sale on Ecsta v700 competition tire, 79 bucks a piece. Hell I'm going to pick up a few at that price and store them till needed.

I have a convertible with 11" wheels on the back. the tires are 315-35-17 and they stick out a little, but they don't rub.

I've seen people talk about 335-35-17's for these wheels, but never seen them on a wheel.

I think if you look in my profile, you'll see a picture of the rear wheels and how much they extend beyond the fender.

Good luck.

thats about the look I was wanting, I have the same rims so I should be close when I find the tires. Found the Nittos for under 200 apiece online, local dealer wants 260 apiece for them.

thanks again for the advice!

I have used Tire Rack's installer network before and it's the way to go IMHO.

helphos

I know they aren't for everyone, but I just pulled the trigger on these. Very low risk for the money. Most reviews were pretty good, and I'm in the market.

After shipping and installation, It will end up a couple of six packs less than $300 for a pair.

Ordered the Nitto 555 Extremes tonight. 194 apiece with free shipping, Road hazard replacement was an additional 24 bucks.

helphos

Hope you like the Nittos. They've gotten good reviews.
The Tire Rack experience has been a good one for me. Bought tires on Thursday, and they showed up at the installer's shop today (Monday). Pizza delivery takes longer than that!

Just order a set of Firestone Wide Oval Indy 500's. Based my purchase on customer reviews, price, performance, ride quality and wear. I was going to go with Nitto, but heard they run a little small, and the reviews said wear may not be as good other brands due to the compound. That said most everyone agreed you can't beat Nitto performance for the price. I will report back on the Firestones later.

I looked at Tire Rack but went with Discount Tire Online (free shipping). Ordered them Sunday night, according to the tracking number they sent me they should be here today.

Are filling them up with nitrogen?

helphos

I'm filling mine with helium. I figure the weight reduction will give me another 5MPG.

If it's too expensive I'll use a 90% nitrogen 10% oxygen mix from my home air compressor!
