^^^yeah, everyone with stock 20's run 275/55/R20's straight from ford....anyways, the 275/55's are 31.9" tall and the 275/60's will be 33" tall so if you can get them for free you might as well...however, IMO if you have a 2.5" level kit i would be looking for something a little bigger/wider tire, i have an 09 without a level and am going to get the cooper zeon LTZ 275/60/20's and they are going to run around $700 for the set. sorry no pics yet, if anything, get them and sell em' for some "meatier" tires. pretty sure 305/50 (33") or 305/55's (33.2") will work and will be about 12" wide...maybe someone else can back me up on this?
