Mine is an sv so one gonna go 275/70 18I have the cam bolts but haven't put them in, truck lined up without them (took it in for an alignment).
I have ordered the Dirt King uppers just to be safe or for future upgrades ( no contact or any problems like it is so far). Once I put the uppers on I'm going to install the cam bolts and get one more alignment.
On my PRO4X I was able to squeeze 305/65 on my stock 18" rims. Those are the Falkin Wildpeaks. Pretty tight but no trimming and no rubbing.
Same wild peaks though
