Not sure on tire size but it's my sons truck and he's looking at 22x11" rims in the rear and 18x9" in the front. The rear tires will tuck under the finder and have a tri 4-link with coilovers. I thinking when we autocross we going to put 18x9 and BF G-Force 335/30ZR18. But we not even thinkng that far ahead yet.
