the only difference between your tire being a 50 and his being a 60, I'm guessing you mean 225/50/16 vs. 225/60/16 is that the side walls on your tires are a little bit shorter. Which translates in to less side wall roll. Meaning if you should go into a hard turn your tires will roll onto the side wall less and they will keep more of the tread on the road where it belongs.
