Since we're talkin tire, I'm curious if a 235/40/18 is gonna have clearance issues, I know it's a wide tire but I like the fat tire look and if I did my math properly it's goona be closest to my stock speedo

As to using '45' or '50' aspect ratio tires. I would go for the 50, your ride quality will be better..(little more sidewall for cushion)...
just my .02

The 235/40R18 will clear fine. I had a toss up between those or the 225/45. I decieded I wanted a little more height. The Goodyear Eagles I got are about as wide as the 235 anyway.
