Hey guys, I am looking into putting turbo wheels onto my C4 cab. They are 18X8 inch in F and 18X10 inch in R. What size tires can I put on here. Ture rack says that 225/40 YR 18 for the front and 265/35 YR 18 for the back. Can I go any bigger than this. Could I do 235 in F and 275 in back? Also, has anyone had experience with BF Goodrich g-force T/A KD(W-2)? I have heard good things about them and the C&D tire challenge they did well in both dry and wet. Any advice would be appreciated. Mainly looking for what the biggest size I could get on the turbo wheels, what offsets I would need for a C4 cab, and are the BFG tires good?

 

For 18X8 F and 18X10 R, I've used 225/40/18 F and 285/30/18 rear on my old C2 cab.
