18x8 and 18x9 wheel size. What is the widest you would recommend?

You can 20% over and be safe. So rear can do 275 and front can do 245.

@synolimit I'm still new at this and was wondering how you arrived at those numbers. 20% of 225 is 45, so that would be closer to 265 in the front and closer to 295 in the back. Am I missing something? Thanks in advance

i'm sure the wheels can stand a bit wider tire; but check close;as each tire maker can be as much as 1-2" different on same sizes,,,also think about if you want shorter or taller tires.
not sure the serie's tire's you are looking at/ the 295 is probably in a 35 series & barely over 26" tall ? Michelin PSS's are 10.8" tread,11.9"section & 26.1" diameter,,,that's on the 295/35
you would have a slight bulge for sure-not saying it won't fit though.

But with a tread width that much wider than wheel width you aren't really going to get much better traction than you would with the 275 or 285... You are just paying more for bigger tires and a very very small performance gain.
