Biggest tires I can run

[weazel]

I plan on putting an 8" coil spring lift on my truck, what is the best size tire to run, I am thinking 37"x12.5" it's a dually so I am limited on width

42.5x13.50 boggers imp: 8" lift is pretty big, I run 37s with my 4.5" EASY

Wow, didn't see that a tire that big fitting

I have a buddy that ran 40s on an 8"

Tire selection for the dually will be more difficult, I too would stick with a 12.50 tire. 37 or 38x12.50 will look good.

My buddy ran 38x 15.'5s in the front on his dually and they rubbed bad. Dente up the bottom of the fenders pretty good just from normal driving. He put big spacers in the rear and ran the same size in the rear. He had 38x11 boggers before on it and they didn't rub at all except on the leaf springs real bad if he turned the wheel close to full lock. Tore a lot of lugs off the inside of the front tires. I would not suggest boggers just because the lugs stick out so far.

that truck had stock rims, i wonder if the OP will be adding rims for more clearance.. if not, i wouldnt even go as high as 8" maybe 5.5" icon kit and 37s??
