Hi Everyone,

I had a set of 275 60 15 ET Street Radials (The discontinued style) on my car and they fit perfectly, then we stepped up to the 275/60/15 Radial Pros and they rub pretty bad on the quarter panel and seem much bigger.

They're a great tire but I was wondering if anyone knows if the ET Street R is narrower than the radial pro and maybe more like the old ET Street Radial in size?

I called Mickey Thompson but they just quoted me the specs on the website, the old design Street Radials were listed at 11.10" section width and the new radial pro tire at 11.40" section width - the difference in width seems much larger than that to me.

Thanks for any help you all can provide!!

The pros are bigger than the ET Streets. I just bought a new set of the 275-60-15 ET Street R's to replace my Hoosier's since they too rubbed. I know the Hoosiers run wide and was told they are similar to the pros so that is why I went with the ET Street R's. I think my new tires are about a 1/2" narrower overall compared to the Hoosiers I had.
