Requires: This is a TIRE SIZE, not a vehicle-specific part. 275/60R20 is roughly a 33 inch tire on a 20in wheel and is a common fit on a stock-height or lightly levelled Ram 1500 rather than a lifted one.

An all-terrain tire in a size that suits a Ram 1500 running stock or near-stock height. It carries the three-peak mountain snowflake symbol, which is a real severe-snow rating rather than a marketing badge, and Toyo backs this size with a 65,000 mile treadwear warranty.

why this one — This is the pick if the truck mostly lives on pavement, sees snow, and only occasionally leaves the road. The three-peak rating and the 65,000 mile warranty are the two things the Nitto Ridge Grappler in this catalog does not offer, and for most owners they matter more than extra off-road bite. The trade is real though: this tread gives up ground to the Nitto in mud and on rock, and at roughly 33 inches it will not fill a lifted truck.
