37x12.50R20 is original equipment on Ford F-250 Tremor (2020-2024, lifted), Ram 2500 Power Wagon (2014-2024, lifted), Ford F-150 Raptor (2017-2020, lifted) and Chevrolet Silverado 2500HD (2011-2024, lifted), among others. Always confirm with the sticker inside your driver's door, because trim levels and wheel packages can change the size.
What is the best 37x12.50R20 tire?
For most drivers our mid-range pick, the Toyo Open Country A/T III, is the sweet spot of price and tread life. If you keep the vehicle a long time or drive in heavy rain and snow, the Nitto Ridge Grappler is worth the extra. On a tight budget the Ironman All Country M/T is a sound choice.
Can I replace just one or two 37x12.50R20 tires?
On a front- or rear-wheel-drive car, yes: replace in pairs on the same axle and put the newer pair on the rear. On all-wheel-drive vehicles most makers want all four replaced together, or a new tire shaved to match, because a difference in circumference strains the drivetrain.
