1.

Enter Stock Tire Size: Input the Width, Aspect Ratio, and Rim Diameter of your Tacoma's current tires, found on the sidewall.

2.

Enter New Tire Size: Input the dimensions for the new tires you're considering. This could be a larger size for a lift or a different style.

3.

Compare Dimensions Instantly: The results table and visualizer update in real-time, showing the difference in diameter, width, sidewall height, and revolutions per mile.

4.

Check Speedometer Error: The calculator automatically shows how your speedometer reading will be affected, helping you stay accurate and avoid speeding tickets.

FAQ

Frequently Asked Questions

This depends on the generation. For a 3rd Gen (2016+), most owners can fit a 265/75R16 or 265/70R17 (approx. 32 inches) without a lift and without significant rubbing, especially on stock wheels.
265 is the tire's width in millimeters. 75 is the aspect ratio, meaning the sidewall height is 75% of the width. R means it's a Radial tire. 16 is the wheel diameter in inches that the tire fits.
Larger tires travel a greater distance per revolution than smaller stock tires. This means your truck is moving faster than the speedometer indicates. This calculator helps you see that difference so you can drive safely and be aware of your true speed.
Offset is how far the wheel's mounting surface is from its centerline. A negative offset pushes the wheel outward, which can cause rubbing on the fender or bumper. A positive offset pulls it inward, which can cause rubbing on the suspension components like the Upper Control Arm (UCA).
