245/40/18s all around???

[04YellowGoat]

I am getting ready to buy tires for the stock 18s I bought for my '04 and I have a guy that swears up and down that you can fit 245/40/18s in front and back with no problem. He says that he has put them on multiple GTOs with the stock 18s and no one has had a problem with rubbing. I have heard from others than anything bigger than a 235/40/18 on the front will rub, but I am wondering if that is because they are using aftermarket 18 inch wheels. Any one has experiences they'd like to share? I am getting the tires on Thursday, so if anyone has had experience (good or bad) with 245s or bigger on stock 18s please let me know!!! Thanks for your help guys!!!:D

I have both 235/40/18 AND 245/40/18 and neither rub. It also depends on the tire. Some tires are slightly taller than others even though they are the same tire size. I noticed my Toyo's (245/40/18) raise the car slightly.

I am running 245's all the way around with my 18's. But, I am sure my offset is differant than the stock 18's. Mine are MC2 wheels that are made only for the GTO, and only offered for 2004.

Here is a pic of them installed and the wheel turned to show front strut clearance.

Just so you know. That rusty rub mark is from the stock wheels. I have them on for winter storage, and they rubbed.

i have stock 18's (from the hsv gto, but same as stock us wheels) with 245/40/18 toyos all around. no rubbing at all. its all going to depend on the brand of tire, some will rub, some wont.

18" Toyo Proxies 4 245/40/18 = NO RUB FOR ME

BFG KDW 2.......does anyone know if these will these rub?

[RobertHammen]

They do run a little larger in the 245/40/18 size than other tires in that same size... no personal experience with them.

I was just wondering the same thing. What about just running the 235 out front and the 245 out back?

Nitto NT555 Extreme 245 40 18's all around

no rubbing at all

Thanks for the info guys!!! I am going with the Potenza RE750's and I believe those are similar to the Toyo's as far as the height of the tire. It does seem to me that the BFGs do run a bit larger for some reason. My mom has the RE960s on her G35 and the tire wall on those looks pretty "slim". Well, the guy is a friend of mine and says that if I have any rubbing issues to bring them back and he'll replace them with a set of 235s, but hopefully that won't happen.

Im a little nervous about my Nexen 245/40-18s fitting in the front of mine. If they dont fit, would getting some spacers have any bad effects on the car? Or would it be a much better choice to grab some 235s?

I think that may depend on what 18s you have. If they are the stock ones from GM, it sounds like you probably won't have a problem. It seems like most of the problems with spacing comes in when you buy aftermarket 18s.

[Goatfury]

yeah they are just factory 18s...I just really hope these Nexens dont run big.

whoops just found this post after i brough another one back from the dead. but yeah are spacers safe??
