i think my tires are perfect for 17's i tire store originally talked me into 60 series but the looked way to big, plus id like to eventually go 5" drop int the rear and it looks like they would rub during towing. so had them switched to 55 series. i have pics if needed.

 

There ya go.

Pics are always nice!

 

pics would be cool, im pretty sure im going with a 275 55, then a 3/4 drop, the truck looks alot like GMracer's, cept mines pearl black and will have the 17's instead of the 20's, same front end and everything, truck has came a long way since i first got it..
