Max Tire Diameter?

My f250 has a 4" BDS lift on it and I will need some new front tires soon. I am debating on replacing all four with bigger tires and I am currently sitting on 295/70R18 Nitto Terra Grapplers (Diameter of about 34.5") and they seem to have decent clearance. I was considering going to the Trail Grapplers... Any ideas if 37s would fit on a 4" lift?

I am also trying to keep my mpg in check and would rather not go with a larger tire and have a 2-3mpg drop by only going up 2.5" in diameter. Any feedback is appreciated and thanks in advance!

Currently running a set of trail grapplers, 37x12.50 on my rough country 4" lift. Only issue I had was rubbing the front valance (wasn't rubbing much at all, just took the bottom corner edge off it), and rubbing my leafs at full lock. But then again a lift kit from company X may sit at a different height than company Y. I also didn't notice much of a change in fuel mileage if any at all going from 35x12.50 to 37s.

01 extended cab long box F-250 4x4 150,000 and still Rollin. Brand new 4r100 and ts 6 position chip with custom tunes, Garrett gtp38r turbo,Diamond eye 5" turbo back, RiffRaff FRx, RiffRaff HPx, 6637. 4" lift on 37x12.50xR17 with black addict xd series wheels. More to come soon!
