315s ?

[GT 5spd]

I am thinking about getting some 315/35/17 on my 98 a GT. I will put them on a 10 1/2 inch wheel... So my question is what kind of rubbing issues will i have?

 

[TweekedGT]

Depending on the tire, Zero. I have 315 Nitto 555r's on 10.5's and don't have any problems. I have heard they have a little smaller footprint than other brand tires though. If you go the Nitto route, no problems.

I am thinking about going with the Sumitomo HTR Z...

I have those

17X10.5 Black Chrome Cobra rims in back 27mm offset. 315/35-17 Sumitomo HRT Z tires. Lowered about an inch or so. A little rubbing "I THINK". The reason I say that I think is that I think I hear them bump the fender when the rear compresses and it looks like the may be rubbing a little on the tire but it is not enough to be damaging the tire in any way or tearing them up. I am going to try rolling the fenders tomorrow if the weather is good. I found a little tech on how to do it. That way I won't even have to "THINK" that it is doing it anymore. Here are a few picks of the fitment if you can see from that distance.

^Zero????
As long as your not lowered to much, you should be fine. SOME CBs rub...but that seems rare. In that case you could probably heat the pipe up, and move it a little.

nittos are a full inch narrower than 315 BFGs and Goodyears, and about 1/2 inch narrower than Sumitomos

If you have a basically stock GT, I think 315s are a little overkill. they look good, but you dont have the power to merit the extra traction, and the extra rotating mass is certainly going to slow you down a bit. Just my $.02... when I get new wheels, I'm going with 275s MAX in the rear

 

[cvgtpony03]

Woohoo I came in second!!!!

Haha. You are right. I did notice a little power get sucked up by the fat wheels but I will be blown soon hopefully so that will be taken care of. That is a nice graph/comparison. I like that. Never seen it before. The little loss in pull is still worth it right now though for the extra grip. MY A$$ IS PLANTED.

I want to get 18x10.5 in the rear for my 99 cobra. I will be putting on sportline springs soon and want to know if I'm going to have problems with the IRS with those size rims. If not, could I put on 285s or even 315s without rubbing?

btw...nice graph

 

[wannabe2000GT]

just do it and ignore the sientific bull ****. its straight dude. it looks BADASS!

Ive got sumitomos 315/35/17 on a 10.5 bullitt on my 96 gt, no rubbing issues what so ever, i have 275/40/17s on the front, they are very close to the strut but they dont rub just very close, I say go for it.......looks awesome

You guys who can slap them on a 96-98 GT are lucky. There is no way 315's would clear my Bassani exhaust. I've got 255/40s on a 17x9 rim with just about an inch clearance right now. I doubt if a 10.5" wheel would fit on mine.

I am putting them on my car. Soon as I get the H&R Sport springs and LCA's installed I am removing the quad shocks so they will fit.

 

[98blackmagic]

I have 315/35 BFG DR's on my 98 and it has Eibach springs and no problems.

I forgot to add i have Steeda Sport springs.......I have a buddy who has some BF Goodwrench 315s and i put them on and they were rubbin the quad shocks and the Ebrake line bracket.... so i took the the quad shocks off and moved the bracket..... In the future i will prolly relocate the quad shocks later..... Thanks for the input guys and nice graph i will prolly order the tires and wheels first thing monday morning.
