I am planning to buy a set of Nitto Ridge Grappler tires for my 2010 Ford F-150 SVT Raptor SuperCab. What is the biggest size of tires I can buy for my truck that won't have any rubbing issues?
Looks like you may be the guinnea-pig here, & you'll be sharing that information once you find-out the hard way !
Ask the folks that actually fit-up these tires would be my suggestion. They'll know where your limits are.
You'll find that plenty of owners may opt-out for a "Lift-Kit" where possible, & from here, you can shove whatever size tire you like under there without worrying about striking your fenders.
Lift-kits however reduce cornering speeds, & generally poorer all-round handling are to be experienced to to the high-center-of-gravity created.
