I recently have been told that i should not put 315/35/17 tires on my car. The reason being that its too much rubber and it will create too much friction. Any ideas? is this true?

 

No such thing as "too much friction" lol. Are you going for the look of 315's? If they will fit on your CTS-V then it's all up to you. They will be heavier than 275's or so, but more "friction" is not a bad thing. Ya wanna hook or ya wanna spin?

 

well put.. this was my argument also and a buddy of mine said the same thing, but no there actually for my TA gonna roll the fenders do u think ill have to hammer in the wheel well at all?

 

Depends on the rim offset, but from what I've read on here most T/A guys only have to do minor BFH to the fender to get 315's to fit fine. Rarely would you have to roll the fender, unless if your rims have really low offsets.

I say go for it, your rims are at least 10.5" wide right?

 

oh yeah i was looking at the zr1 replicas from oewheels 17X11 rear and 17X9.5 front i think the offset is like 54 for the rear

 

You should be fine then, maybe minor hammer to the inner fender. I'll let a T/A guy post to let you know for sure.

 

No such thing as too much rubber, but I must say those wheels will look horrid on a cts...they look bad enough on fbodies. A dated looking wheel like that on a very new sharp looking car like that is just a bad combo.

Like putting cragar s/s wheels on a 4th gen or a c5/c6 corvette

 

They're for his TA (post #3)

 

there is such thing as too much rubber, if we are talking about drag racing. if you can dead hook on a 245, then a 315 will slow you down. it creates rolling resistance. also, it is rotating mass. and unsprung weight. all bad. there's a reason people run skinnies up front.

really, it won't make a huge difference unless you're trying to squeeze every 100th out of it, but there is truth to it.

 

...eh...doesn't make much difference

OE should hurry and get the 11.5" wide c5 y2k dished wheels if they haven't already, those are sexy as hell on t/a

 

True, but in 17" they look pretty damn identical to ZR1's IMO lol. The 18's are very nice though.

 

Yeah I have 315/30/18 dr's on my car and had to do a lilttle massaging with my bfh in a few spots.

 

zr1s are thicker with uglier spokes and scream 90s IMO

 

Those C5DDs are 18's, the 17's have shorter spokes that resemble ZR1s.

It's all opinion though, all that matters is your own.

 

Is that polished or machined face?

 

who cares about friction tractions better

 

machine face, 18x10.5 all around.

 

lol to much rubber wtf?

 

newb question. What exactly does "rolling the fenders" mean, and how do you do it?

sorry to hijack

 

What size tires do you run on the 18x10.5s. I was thinking about either running a 315/30/18 all the way around or 295/35/18. Will a 315 fit ok up front?
