mid 1.7's on 285's and low 1.6's on 265's. power was also different each time so that has to be accounted for...
i have 265's now and they look too small, i want to sled pull and go to the dunes / track next year so ill likely go back to 285's.
285's suck in the snow compaired to 265's!!! ive already had both on for a few winters and 265's were the waY TO GO
