Replacement Tire Pressure Calculator

Calculate proper tire inflation for replacement tires to match the original equipment tire load capacity on your vehicle.

When replacing original equipment tires with a new tire size, typically there is a change in tire load rating, which may require adjustment of tire inflation to comply with the original tire's load capacity. To get proper inflation of the replacement tire, you have to reference tire load and inflation charts and find corresponding tire load capacity and inflation that matches or exceeds the original tire's load capacity.

Keep in mind that the maximum pressure listed on the tire sidewall is not necessarily a recommended tire pressure for your vehicle's tire size.
