Wheel Clearance 6" lift suspension 3" body lift - Clear 37 x 13.5 R20 12" Width

[justin93]

As the title says.

I have a 1993 chevy K1500 1/2 ton 5.7 TBI 4l60E currently on 35" 12.5 R15 10" width
6" Pro Comp lift suspension with 3" body lift.

I've been contemplating going the size in the title but am i able to clear the 13.50 tire width without rubbing? i will take some fender well pictures and do measurements as needed but am unsure if it will fit without rubbing. The previous owner previously already had 35x 12.5 R16 on them but im unsure if it will take a taller and wider tire.

Contemplations between Toyo Open country MT's and Nitto Trail Grappler MT's anyone running these tires i'd love to hear your experience and suggestions.


Hope to hear from you guys soon, Thanks!

southern pride cleared 37" toyos with his 6.5" lift. i dont think he rubs at all and his are tucked.

I bet you could clear 38's no problem. You got quite a bit of room...

Nitto anything will not last... Open country's or maxxis tires ftw

If I cleared 37/13r16 Boggers with 3" body lift and crank you should be fine for sure!

Currently have 4.56 Running gears by Sierra, Sierra axle shafts, Eaton Elocker posi, complete master install both front and rear and am still in the process of breaking it in. I'm at 250 Miles, never went over 50 mph ( even though speedo tach is off by 5-7 mph) Every 15 miles i shut it off for at least 30 minutes to cool down.
I was told to flush out the gear oil and put in a NON SYNTHETIC 90w-80 ?(i thought it was 80w-90?) and to put in a GM Additive as well. I've never done this before and was seeking the experience and advise of others for the products they used to change there gear oil.

This will be particular to after a gear change break in period of 500 miles so im expecting to see some metal shavings when i drain the gear oils, i just want to use the correct w- oil and GM additive.

Currently running 37x13.5R18 now and when i turn only to the left near full lock it sounds like the tire is rubbing against something.. not sure why but it's only when i turn left on the left tire.

Any help or advice would be greatly appreciated, Thanks.
