You know whats funny, I just droped off my 20's to get fixed up and repainted and I now am riding on 17's with 50 series. Everyone talks about a bad ride from 20's but it feels so much better with 20's than these 17's.oh and i have 30 series tires and 20's, no rubbing, and rides awesome!
i have a 1" drop and i scrape sooooooo much. i couldnt imagine a 1.8"
