Do I need to recalibrate my speedometer after bigger tires?

Installing bigger tires improves acceleration, handling and makes your vehicle look good, but it is essential to recalibrate your speedometer to get correct vehicle speed readings.

Will changing tire size affect TPMS?

TPMS will still work fine, the issue will be the overall diameter. Going from a 235/55R18 to a 245/45R20 is a 1.8\% increase in diameter, going to a 255/45R20 is a 2.8\% increase. This means that your speedo will be reading low.

Will different size tires affect transmission?

Wrong size tires do not damage the transmission. Although ill-fitting tires do not directly impact the transmission, it does impact the overall performance of the vehicle. Wrong size tires can cause a safety hazard as well as cause structural damage to the vehicle.

How far off is my odometer with bigger tires?

1/8” tread wear on a 36-inch tire reduces the circumference by 0.8 inches. Over the length of 1 mile, this adds up to 33.6 feet. After “actually” traveling 157 miles, the odometer will be “off” by 1 mile. It will read 158 miles.

How much does it cost to recalibrate speedometer?

Getting a Speedometer Calibrated Most auto-mechanics perform speedometer calibrations, and some driving schools perform them as well. The cost is usually approximately $75.

Can tire pressure sensors be moved to new wheels?

The short answer is yes, you can use your old TPMS on your new wheels and tires, however below we discuss some points to consider before making that decision.

What damage can bigger tires cause?

First, bigger tires are usually much heavier. Adding a set of four big and heavy tires to your vehicle will add a lot of new weight. That added weight can hurt your car’s acceleration and expend more fuel. It can also put more strain on your brakes to slow down the vehicle.

How does changing tire size affect speedometer?

Up-sizing or Down-sizing Up-sizing, or installing a taller tire, will lead to a speedometer reading that is slower than your actual speed. This is because a taller tire will have a larger overall circumference, which will cause it to travel more distance per revolution than the original equipment tire.
