Frequently asked questions

Do I need to modify my truck if I want 40" tires?

Yes, you’ll need to install a full suspension kit to clear 40" tires on your truck, along with new custom wheels that are wider with a different backspacing or offset than the stock wheels. Fender, bumper or inner wheel well modifications may also be needed to prevent the tires from rubbing when turning, hitting bumps or offroading.

What are 40" tires in centimeters?

They range in overall diameter from 100.33 – 102.87 centimeters.

What size rims do you need for 40" tires?

They’re available in 17" – 24" rim or wheel diameters.

What are the drawbacks to larger tires?

Increasing the overall tire diameter from the stock tires will decrease fuel mileage, increase braking distances, alter the handling of the vehicle, take longer to accelerate off the line, and cause the speedometer to read slower than what you’re actually going.

What tire size is 40" equivalent to?
