# Tire Weight Comparison Calculator

Compare Tacoma tire weights and see the rotational effect of heavier tires. Weight at the wheel behaves like about twice its mass under acceleration.

## What It Does
- Weight change: Total static weight difference across all four tires from a size or load-range change.
- Rotational effect: Weight at the tire behaves like a hoop, so its acceleration effect is about twice its static mass.
- What it costs you: How added tire weight affects acceleration, braking, ride quality, and fuel economy.

## Summary
- Compares two tire weights and the total change across four wheels.
- Weight at the tire behaves like a hoop, so its acceleration effect is roughly twice its static mass.
- Heavier tires hurt acceleration, braking, ride, and MPG more than the same weight in the body.

## FAQ
### How much does tire weight matter?
A lot for its size, because it is unsprung and rotating. Weight at the tire behaves like roughly twice its mass under acceleration, so a few pounds per tire is felt in acceleration, braking, and ride.

### Is one pound at the wheel really ten pounds?
That saying is exaggerated. The defensible figure is that a tire behaves like about 1.6 to 2 times its static weight under acceleration, because its mass sits out at the rim like a hoop.

### Do heavier tires hurt MPG?
Modestly. Heavier, more aggressive tires add rolling resistance and rotating mass, which is part of the 1 to 3 mpg loss owners see moving to larger off-road tires.
