Torque & Wheel/Tire Size - Toyota Yaris Forums

Pavel Olavich · 03-20-2007, 09:17 AM

I was told that the bigger the wheels/tires, the less torque....is this true? Bigger tires/wheels sap energy...of course not taking into consideration wheel/tire weight, but is this true in general?

very true. More rotating mass to accelerate means less power being used to move the car forward.

Yes, it's true, but you really shouldn't change the overall diameter from stock.

eTiMaGo · 03-20-2007, 11:01 AM

but even with the same diameter, bigger rims will have more weight and thus inertia, which is the main drawback to these sexy 18" rims

Correct! Were saying the same thing, weight is the enemy, not overall tire/wheel diameter. Bigger tire/wheel packages weigh more.

like most things in cars, the less weight the better

In a perfect World, bigger rims would weigh less; then we could have both looks and performance.

A forged magnesium wheel is the fix for this.

Until you kerb it.....

If you can afford them in the first place then I'm sure you're not worrying about curbing.

IMO wheels should not cost more than the car itself, but your correct.

I think in a perfect world, not only would those big wheels weigh less, but they'd also not expose the silly looking rear drum brake.
