Re: Ride height question
The radius difference is 1.5" the difference
215/70/15 20.925
225/50/15 19.429
So the car will sit lower by 1.5", but that's not the key.
The circumference will drop from 7.03 ft to 6.25 ft, a difference of 11.1%.
The circumference will be smaller on the 50/15 tire and while you will loose top speed (yeah from 137.4 to 118.9 mph) you will gain in acceleration. Your not going to be hitting that top speed much (or at all), but you will need acceleration out of slow corners, multiple times every lap.
