I was talking to a less-than-knowledgeable member on here about this. He claimed that he is running 235/55-15 on his Mustang in place of the stock 205/65-15. I am wondering if this is feasible, and safe to do. The size that I to run is 215/55-16 in place of 205/60-16 on a different car that isn't a Trep. I plan to bring these into my autos class and mount and balance them there. I have mounted tube motorcycle tires before and mounting oversized can be a serious PITA. So what do you guys think of this? Thanks in advance for replies.
