I know these "what size tire?" threads get beat to death but after searching i couldnt find any for what i'm looking for. I am going with 18x9s all around and will be keepin the same tire size on all 4 wheels so i can rotate them front to back. I was told that 255/45/18 would give it the same diameter of the stock 17s with the factory tire size. Thats not really a big deal to me. Also trying to stay on a budget here so nothing too crazy. What do you all recommend?

I am looking to get the same combo here 18x9. I am looking for 275/40/R18's.

Unless someone has something bad to say about that tire width?

JMO, you'll be fine with the 275 on a 9" wide rim, but as far as going with a 40 or 45 series tire will just depend on personal preference

anyone know off the top of their head what tire sizes the GT500 comes in stock? They run 18x9 all around

I found this on the internet which shows the front tires being 255/45/18 & the rears being 285/40/18

no problem man.

JMO, since your looking to keep the tires the same at all 4 corners, I would look at doing the 275/40/18's.

you think 40s? I was thinking 45s would be for a better ride

Look on the chart tire places have...
You want to keep the same diameter than stock.
285/40 might be the way to go, for a more aggressive look.
With wheel offset in the 30s or less, it will fit up front as well.
