want FATTER tires
 

I have a lifted 85 k20 6 inch lift 37 inch tires 17 inch wheels

they only make 17 inch wheels 9 inch wide thats it

I want fatter tires so if i sell my current wheels which are new and my current tires which are new and $400.00 each toyo m/t

and then buy some 15 or 16 inch wheels that are 10 or 12 inch wide with some 38s or 40s
ARE there any modifications i would have to make for the rim to fit

Also I have 4.11 gears will that be enough gear for 38s or 40s

thanks

My truck has 4.10s with 38.5 super swampers at its a dog. I'm planning on running 5.13 gears but I wanna run 42s eventually. And my 15x10 rims I had to shave a hair of the brake caliper to clear the 2" back spacing

4.11 with 38s will be a dog.

Wider tires are more likely to scrub the fenders. I've got really wide rims, I could probably fit 40 inch tires if they were narrow, but as wide as my tires are, my 38s don't even quite fit. At full lock, I think I've only got about 4 inches of wheel travel before they'll hit the fenders.

16 inch rims will clear the brake calipers as long as they are steel wheels, Aluminum wheels are too thick. 15 inch wheels will require grinding on the brake caliper to fit, and they need to be steel wheels. Again, aluminum are thicker, and will require too much grinding on the brake caliper to be safe.
