I have noticed people are using different size wheels and tires front to back, is this not a real bad idea? Different size tires have differnt diameters, and turn different RPM at the same speed, thus the smaller narrower front tires turn faster then the larger rear tire. This does not work on a 4 wheel drive car, as they have the same ratio differentals front and rear, and must turn the same speed. I'm supprized no one is having severe michanical problems.
