Thinking about a wider rear tire

[ClassicVW_imp]

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.

Sometimes it's true. I had a BMW tourer and was looking for white wall tires. (Don't say it!) My dealer was both BMW and H-D. Service/parts manager looked it up in the thick tire bible. There was a WW recommended for the rear, but none for the front. Since Harley baggers have WWs available front and rear, I asked him to put one rated for a Harley on my BMW since they both were touring baggers and both bikes were a similar weight and had similar load ratings. He said he would not go against a manufacturers recommendation and refused.

I give that guy credit for that. When I told that story on another forum, you'd be surprised how many people said I should have just bought the tires and found a shop to install them. They completely missed the point why the manager refused the sale- SAFETY.
