A 37-inch tire is a bigger step than a 35. What we stock here is mostly flotation sizing such as 37×12.50 and 37×13.50, on 17, 18, 20, and 22 inch wheels, with a few 24s in the mix. Trust the overall diameter the manufacturer prints on the sidewall. A metric size such as 325/65R18 is not a 37, even when it looks close on paper. If you are still choosing between the two, measure what your fenders will actually clear, and compare this catalog with our 35 inch tires.

Most Jeeps and trucks need a real lift, and often some fender or bumper work, to run a 37 without rubbing. There is no single lift height that covers a Wrangler, a Gladiator, a Bronco, and a Super Duty, because wheel width and backspacing change the outcome as much as the springs do. Start with our Jeep Wrangler wheel fitment guide for YJ through JL, or use the Jeep Gladiator wheels and Ford Bronco wheels landers instead of guessing from the tire height alone.

Load range matters on a tire this large, especially if the vehicle tows or sits heavy on the rear axle. If you want the 37s already mounted and balanced, order them as a wheel and tire package. A mounted set needs 4 to 8 business days to go out; a bare set of 37s goes out in 2 to 4, FedEx Ground, and only to the lower 48. The windows, and the 60-day return period on unused eligible orders, are on our shipping page. We can walk through lift, backspacing, and load range Monday through Friday, 8:30 AM to 6:00 PM ET.
