I have a set of 37s sitting in my garage I was waiting to put on in the spring. However, with the way fuel prices have been going up and what people are speculating them to be this summer I'm starting to get a little leery about putting a bigger tire on my truck and getting less MPG. I have 315s and a leveling kit on my truck now, which looks nice, but I think the 37s with a 6" lift would look a lot nicer. I'm kind of torn on what I should do here. Does anyone have any suggestions? Any ideas how much MPGs I would lose? I'm thinking probably about 2 mpg less.
You could always keep the level kit and do cutouts to run the 37's. Then your truck wouldn't be up in the air so high catching extra wind causing excess drag.
Where do you mostly drive, city or hwy? Either way, I'd run the 37's, but with me I noticed a slight drop (probably @ 1mpg) for city but gained on highway just a touch keeping the rpms at or below 2k.
Well here's a problem. I mounted the 37s on my truck and and jacked the truck up to see if I'll have enough clearance with the new lift. It turns out that the tire is real close to the inner fender only about a 1/4" clearance. I think this will be a problem when the suspension compresses. Is there a way to pull the inner fender out of the way to make some more room? Here's a pic
What rim size and style are they? If your that worried, I'll trade ya for some 35s!
