Tires are 275-40-20's all around, they are what i had so i have to get my use out of them. The rear needs to be at least a 295-40-20 so it dosent looked stretched, as for the drop, i'm not 100% sure but i belive its a 3/5 drop. It was lowered when i bought it. Front uses a 7/32 spacer and the caps trimmed and the dust cap hammered. Bolt pattern is the only thing that fits like it should. I will probaly end up using a 1/2" spacer to widen the stance once i get a set of 295'2 for the rear. Here is a pic of the cap trimmed next to one thats not trimmed.
