I am also looking around for some new snow tires as my Blizzak LM22's are toast.

The problem I have is the sizing for my 7x17 front and 8.5x17 rear winter rims. Originally these came with 205/50 r17 and 255/40 r17 and the resulting tire diameter was virtually identical.

While 205/50 r17's are available 255/40 r17 are pretty well non-existent for snow tires with the Hankook Ice bear being one of the few and it has marginal reviews from drivers.

So is it okay to run 205/50 r17 on the front and 225/45 r17 on the rear? Will the .39% difference in diameter upset the PSM?

Any other options for a Colorado snow tire.

Thanks, Ken
