I got an e-mail today and i need 1 more click to finalize my order. My choice was 39.5 TSL's/// now im beginning to think. With my 4 inch lift and some flexing, would the tires be rubbing against the wells on my box? (85 K10) I already took the inner fenders out of the front and am ready for trimming. I also plan on adding some zero rates. This is a street, trail, mud truck. are the TSL's my best bet? Thanks in advance
