High detail - Very smooth and perfect for extreme close ups, It includes modeled tire treads that bring the poly count to 160,000
Lower detail - It is the same exact rim with one less meshsmooth Illiteration so that on closeups you might be able to notice that some circles aren't as smooth. The biggest difference is that this file has a bump mapped tire instead of a modeled one which keeps the poly count at a fairly low 16,000. Meshsmooth is kept in the models history so that you can easily meneage it.
As you can see there is almost no noticeable difference between the renders of the High and low detail wheels - But if you would like to make large closeups at higher resolutions, you might find the modeled tire treads usefull.
