Ok, let me just say Chicago had it's first snow of this season, last night. My Pat is a 4wd, with the 4whl lock, and from what I've gathered here, and from the owners manual and disc, that makes it the FD1, AWD. Now I've had FWD, 4wd, and RWD vehicles in the past, and I guess I expected more from the Pat on stock 215/60 17's. I plow snow for the munincipality I work for so when they called me out to go plow last night, I also wanted to see how the Pat acted in snow without locking in the 4wd. In the short distance I traveled to work, there was a lot of wheel slippage. Now according to the disc, AWD is on all the time. My Dodge was a 4wd, and in 2wd on stock road tires, it didn't slip as much, and there was only an inch of snow on the ground. But even the FWD VW Rabbit p/u I had up on snowy mountain roads in New Mexico, didn't slide as much as I did last night. Ok, enough ranting, it was the first time, and maybe there was some ice under the snow, but I'll be scrutinizing this Pat on the next snowfall, and I'll have to try the 4whl lock mode, and I guess I'll be looking for a better all season, or winter tire, because trading in the Pat is not an option. At least the gas mileage is better than the Dodge or the Chevy ZR2.
