Frequently asked questions
How much do 37x12.50R18 tires cost?
Expect $230–$367 per tire for a budget brand, $367–$513 for a mid-range tire like the Toyo Open Country A/T III, and $513–$564 for a premium tire like the Nitto Ridge Grappler. A set of four therefore starts at about $920. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use 37x12.50R18 tires?
37x12.50R18 is original equipment on Ford F-250/F-350 (2005-2024, lifted 37 in), Ram 2500/3500 (2010-2024, lifted) and Jeep Wrangler JL (2018-2024, 18 in lifted 37 in), 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 37x12.50R18 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 37x12.50R18 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.
