Am looking at putting plain steel wheels with snow tires on my XG. The new rims available are the right bolt pattern & offset but are 15 X 6, not 15 X 7 so I'm wondering if I should go with a slightly less wide tire like a 195 instead of the 205R65.15 that is on the alloy rim?? Any experience with this ? Thanks, BC in BC (Didn't have any snow till Xmas!)
