what is the narrowest tire I can run on an 16" rim 8" wide? I wanted to run a narrow tire (I'm only interested in snow travelling), but I bought 8" rims. I know, should have stayed with 7's, but I thought someone down the road might want wider. Tire shop says 245's are as narrow as I can go. Any narrower is a plus to me. Will a 235 make it on an 8 wide? I originally wanted to go with 215's, but they look REAL narrow next to those 8" rims.
