Nothing against your experience, but here is rating from tire rack.
Winter/Snow Performance
8.9 - Excellent
9.3 Light Snow Traction
9.1 Deep Snow Traction
8.2 Ice Traction
What would be advantages and disadvantages of both sizes?
17" Sport wheel. No suspension mods...
Currently have stock 255/65R17 Duelers.
Street/off-road 80/20. At least for now.
Thanks in advance...
