is it a problem

[CD5Passion]

I was just double checking with this question but does anyone know of any bad side effects of riding on a rim that has a slight (and by slight I mean very small) bend on the inner lip?

also is there anything to watch out for when looking at used tires?
The rims I'm going to buy have 3 tires that have approx 10,000 miles left on em (according to chris)and one was blown. just looking for a temporary solution to the one tire needed so I dont have to ride on 3 Racingharts and 1 stock
