Gains with Thin Tires? Lighter wheels?
On the tire side of things I was wondering two things:
1. Replacing my steel wheels with lighter weight alloy/Mag/whatever material wheels will give better MPG?
2. Replacing my stock tires with thinner ones give better MPG?
Is the tire/wheel a part of a car that can greatly increase MPG when an optimum tire/wheel combo is used? Or will the gains be so small as to make this irrelevent?
