Need help choosing tire size on lifted 21 Tundra

Hey all! First post here and need some help.

I have a 2021 Tundra TRD Sport outfitted with this:
Eibach Pro coilovers up front (2.75” lift)
diff drop
RC control arms
Toytec shackles in the rear
Method 305 NV 18” w/ -18 offset

When I originally got the work done I had Nitto Terra Grapplers put on (285/75/18) and they definitely rubbed when 3/4-fully turned in reverse (I believe in the body mount chop area) and a tad on the front fender but I pushed that forward for relief. Now it’s time for new tires and I don’t want to have the same problem again.

I’ve searched the forums and checked out the tire size guides that are linked but there’s nothing in regards to a 2.75” lift. I’d like something beefier than what’s recommended for a 1.5-2” level but obviously can’t go for what’s given in regards to a 3” lift.

Anyone have a similar set up or tire size recommendations for a 2.75” lift and -18 offset?

 

You can search those parameters on Customoffsets. Alot of it comes down to offset. I'm wondering if the 285/70/18 would be the best for your setup.

 

I have a ~ 2.5” lift (Bilstein 6112/5160, shims and Coachbuilder +2 in back), so smaller than your lift, and Falken AT 285/75/18 “pizza cutter” 35” tires…same rubbing your having (only reverse drivers side)
The solution was buying a new front bumper…problem solved and looks awesome ….Could fit 37s easily now , should’ve bought true 35’s (12.5” wide vs my 11.6”)
I believe if you’re gonna spend all this $$$ on new suspension/wheels/tires, why wouldn’t you spend $1,500 more to completely solve any rubbing issue?

 

I have the eibach setup set at 2 inches and run 285/75-18 on stock offset wheels. Any less offset and I would need to spacer the bumper and lose the mudflaps.

That negative offset wheels will make fitment more challenging for you. It is going to make larger tires want to scrub the bumper and body mount, which you can address. +20 to +35 offset is generally the sweet spot for larger tires on the tundra.

Do some internet searches as well as here and check custom wheel offsets site for truck with similar negative offset setups. Or just modify the bumper/swap in non stock bumper and do a body mount chop and you should be able to run 35x1250, maybe even 37s without rubs.
