Looking to maximize what I currently have as far as wheels. I have two sets of 17x8's. One has a set of 245/45/17 RE01R's and the other has a set of Sumitomo HTRZ's (1st Gen) for DD use. I know that 245 is the ideal size for an 8" wheel as far a standard fitment goes and 255 is ok too although it is slightly outside of the suggested range for an 8" wheel. I know for autocross, its common place to see people stuff huge widths on wheels that are several inches too small but that is for limited autox use and necessary because of the stock width requirement. My question is what is the max size that I can run on the street and still maintain safety. Can I squeeze a 275 on there and be ok for street use day to day if needed. I'm also thinking that if the 275 wont work ok for the street then I may still run it for autox only and only drive it on the street to and from the event.
