Tire size/clearance 255 75 R17

Hi I just purchased bf Goodrich mud terrains from a buddy.
Size 255 75 R17

Do have to put a leveling kit or spacers to fit these tires or will it be ok.

 

Those are a little taller and skinnier than stock. I think they'll be ok but I'm no expert. There are a ton of threads on this u could search and reference

 

Thats a funky size. Its a touch bigger than 265/70r17 which is generally considered the biggest tire that will fit without trimming/lifting. It will be close, you may have to trim a little plastic though.

 

They'll fit assuming stock wheels

 

I am running 31s on a 2.5 inch leveling kit. Would I be able to run 33s if I am planning on getting 18/9 wheels with a -12 offset.
