If 4 people in the car doesn't scrape now, then 4 people in the car won't scrape with 20" rims PROVIDED the mounted tire has the same diameter then as now. As the rim diameter increases the tire sidewall section height increases by the same amount to maintain the overall mounted wheel/tire diameter. I would shop for tires and rims together to make sure you can find (and afford) proper tires for the rims you want to install.....

Sorry, but I must be misunderstanding. Maybe the the 20s are also much wider leading to scrapes while turning??
I had issues with a K5 Blazer scraping, but that was due to excessive tire size.

Agree that 20s would look fantastic....mine has 16s and would like to upgrade at some point.
Maybe a picture or drawing would help me understand how it's scraping....
