I am looking to get some wider tires for my RT. All the tires I want dont fit the stock rims (they are not wide enough). I have identified a set of rims to do the job, but before I go that route I wanted to find out if it is possible to have the stock rims modfied. Can you get the stock rims cut and then widened by adding a welded piece? If so who does this kind of work? Is it recommended to do this?
