The 60's fit a lot better on the stock width rims than the 50's do. The 50's definitely will wear funny. The 275/60's wear OK and Hook OK. An 8" rim would work better, but they'll work fine on a 7" rim.
GN rims will need a small spacer to keep them off the frame, but T-Rims will usually not rub in a straight line with 275/60's.
