Tire Question

Okay, I have a 2007 King Ranch PSD, with 20" tires. I had a 2" lift kit on it and I am running 35/12.5X20 and I have a couple of big sales coming up and was wondering, would 37X13.5R20 fit on my truck with no further lifting? As is

Thanks,

The 37's would most likely require some fender trimming to keep them from rubbing.

If you have 35's now, so can turn the wheel to full lock, take a floor jack and raise just one side (to simulate the suspension flex when hitting a bump) and see / measure how much clearance you have now with the 35's. If you can comfortably fit your thumb width between the closest point of contact between the tire and whatever the first part of the truck the tire would hit, then you should be able to run 37's, if the thumb width doesn't fit, then you know where you'll need to trim.
