315/70/17 on 2006 tundra

I have a 2006 Toyota tundra with total chaos, upper control arms and 2.5 coil over shocks in the front. I recently got 315/75/17 on my truck and when I take it off Roading it rubs on the bed and is messing up the tires I was wondering what I can do for the back or the front Because it also rubs

 

Rubs on the bed, like the rear wheels rub when articulating? Sounds like you may want to lift the rear with an add a leaf or new leaf pack. Gen2 with same tire size, but 2.5" rear lift and clears during articulation with stock offset. Depending on how the tire is tucking in, changing the offset could help too (spacers, but not ideal).

 

Pics would be great here but that is a whole hell of a lot of tire for a 1st gen.

 

If you wanna keep that size you're gonna do a lot of cutting and smashing on the firewall. Even then, you'll still probably rub on the frame. That's a 35.5x12.5x17. Jesus.

 

70s or 75s? Title and post say different. Either way it’s a big tire on these.

 

Regardless whether it's 70 or 75, at 70 it's almost a 35" tire, which is too large for these trucks without significant lifting, like 4"+. If it's actually 315/75r17 then it's 36" and that's way too large, even with a lift.

There's no way you're offroading in that tire comfortably without regearing, what are you currently running gear-wise, and where exactly is the tire rubbing? Also, what are your wheel specs (width and offset)?

 

Sell those tires to some dude in a dodge and buy some 33” tires. Problem solved.
