Since this forum has answered a lot of my question before, I think this is the best place to ask!

I'm putting a set of Ruff Racing 279's on my '03 Coupe. The specs are front= 18x8.5" and rear= 18x9.5", both with 20mm offset. I have a set of BFG G-force T/A's that are in excellent condition that I wouldn't mind reusing. They are front= 225/45/18 and rear= 245/45/18.

The questions I have are: Will my currect G-force's fill wheel wells and look good? and: How wide of a tire can I fit on the Ruff wheels without any type of rubbing?

Thanks for all your help!!!

 

you could fit 275/30F and 295/30R if you wanted to. I just dont know if you'll like the look.

I wouldn't recommend a 275 on an 8.5" wheel or a 295 on a 9.5" wheel at all

 

i know, neither would i, but it can be done.. he was recommending the widest so i gave it... actually you can fit a 285/30F and 305/30R if you really wanted to.

you still wont rub, trust me, it's been done. Scott Bush (professional race car driver) at Relentless Autosports Runs 285/30/18F 315/30/18R on Nismo LMGT4 wheels (8.5/9.5) on all of his cars and has no issues whatsoever so you cant tell me it wont work, it's been done.

All I was saying is he asked specifically about his RUFF wheels, not the widest tire he can fit in general

 

race tires also have much stiffer sidewalls that can handle the narrower tires, street tires do not, throw a 315 street tire on a 9.5" wheel and you are asking for trouble

 

To the OP, 255/40/18 and 285/40/18 is the widest tire you can fit on your wheels

 

he uses street tires on his car as he races in a street class with the JWT TT cars built at his shop. I realize he was asking the widest for his ruff wheels, but they are the same size as the lmgt4's... he asked for the widest... he got the widest.

agreed, for everyday street driving those sizes are perfect.

actually he uses 18x9.5 all around, and for street tires he uses Bridgestone Potenza RE050A Pole Position Tires - 285/30/18 Front 295/30/18 Rear (Street RWD). The 315/30/18's he uses are r-comps, and on axis reverb 18x10.5's.

that's on one of the cars, he's got more than one car, trust me, he lives 15 mins from me and i talk to him at every meet we go to.

Let me try to rephrase; Do you think my current G-force's will look good on the new Ruff 279's? Will they fill the wells or do you think I should go wider? Do you think the rim will look too wide for the tire?

 

IMO yes, it will look retarded, get some bigger tires, 255/40/18, 285/40/18
