Thinking about a wider rear tire

[Randy B]

This probably isn't true, but I would hope any good service shop would refuse to mount a 180 tire on a 4" rim. I wouldn't even risk a 160. Now, if going to a 150 gave me better or more diverse tire options, that's definitely something I would consider (sadly, it doesn't ). But I would be really weary about going over a +10 on the tire width. Good luck to you Sil, keep us posted about what you decide, and how it works out.

Think about this and then take a good look at TOO MANY of the imports running around on wheels and tires that shouldn't even be in the same zip code with one another, let alone mounted to each other and then postulate the chances of someone mounting the incorrect tire on a too narrow/wide of a rim for it. There are stupid people out there and unfortunately they walk among us.
