Recommendation
Select tire size, position, and enter axle weight to see recommendations.
Always check tire pressure when tires are cold (before driving or after sitting 3+ hours). Hot tires read 10-15 PSI higher.
Under-inflated tires increase fuel consumption by 0.2% per 1 PSI drop and accelerate tread wear. Over-inflated tires reduce traction and ride quality.
