(ET) Snow and good tires

[The CZ Unit <cz alembic crystel com>]

Got a few inches of snow last night so of course I fired up the snow 
blower. The 36 volt lift (running it at 36v) works great, goes right up 
and down without issues.

Likewise I noticed I was able to blow with no issues without chains. 
True that it is a lot less snow than 2 feet, but still the old tires 
used to slip and slide on anything. I think new tires make a spectacular 
difference.

Also today I drove the kids out to the hill for sledding on the 
E15+trailer. No problem driving through the snow out and back. Same tire 
deal.

So replacing the old tires, even if they have plenty of tread, is a good 
idea. I wonder why.
