Wheel weights, Which I just put an ad in the want ad section, even though too far for you, will help in the snow. Before adding the weight I would just sit there and spin the tires. The weight of the front blade will make the back on the tractor a little lighter. Fluid in the tires is another option. Chains will also help on a gravel driveway but will leave marks or possibly tear up a paved drive. You could also add a heavy implement or concrete block off the 3pt will help.
Basiclly is you don't have added weight on an incline you ain't going anywhere. If you get chains I would suggest the big ring chain. The small link chains tender to fall inbetween the lugs making them unless.

Kirk I just purchased the LTX M/S2 about 2 months ago based on some feedback here, Tire Rack, and Discount Tire website. I too was between the Latitudes and the M/S2. Ended up going with the M/S2 because our winters can get messy and we do a lot of winter traveling to Iowa so I felt the M/S2 would be the best for our situation in the winter. Tire Rack’s rating was higher in the snow category so that was my deciding factor. They also came recommend by the tire store as well.

We just got back from a 3500 mile trip and tires performed very good. Obviously much better than the GY Integrities and I felt much more confident in the rain with these. About the only downside is my mpg’s went down about 2 mpg’s on the highway, but I had read that in a few reviews so it wasn’t really a surprise. Still got 20-21 mpg’s on my trip, so can’t complain.

I think they are both good tires from the reviews I read. My local Discount Tire store matched their Discount Tire Direct website(mail order website) and I got them for $690 installed and out the door (didn’t purchase the tire rebate protection plan).

Good luck
