15" tire size on 90q

[Mark J. Besso]

They do appear slightly shorter and leave more of the wheelwell exposed. 
 That reduced height also makes for an inaccurate speedometer by 10%-12%.

I've since gone to 17x7.5" wheels with a 25mm offset.  I chickened out on 
staying with the 215mm cross-section and went with 205/40-17.  There's more 
than enough room for the 215/40-17 so that's the size I'll go to when these 
wear out.  As Grant says, that extra width would've provided some good 
protection for the rims.

  A slightly larger tire does protect wheels from bends....
