I am looking at putting slightly bigger tires on my challenger. I have the 20in rim. It's 245/45. I am looking at trying to put 275 on the back, but was wondering if the rim would be to small to put that size tire on that rim? I don't want to replace the rims because I like the stock rims. I read another forum on here, but was outdated by about 4 years or so. I would like to go bigger then 275, but don't think that would happen at all. Anyone on here experiment with different tire sizes on the 20in rim?
