Doesn't take rocket appliances to know that Michelin X-Ice Snow's are the best option for snow! Solid choice Raveen.. errrr... Ricky.
Mine are freshly dressed and look pretty greheheheasy with camera flash on, but I love them!
I also have a 20" rim. I spoke to a few tire shops about 18" and they all said it's too close to the larger caliper and if you deal with any wet snow it could be an issue. Surprised you got away with an 18"
@hogdust, but if it works, good on you! Certainly cheaper.
