You will have to expand on the X1.
Is that the Michelin Super Singles??
We don't run super single tires AT ALL here in the west.
You are correct that you have to chain up a single axle truck
way sooner than a tandem axle drive truck.
There are many times that you can get by with a three axle truck, when they slap the chain required sign for single axle trucks when there is a hint of snow on the road.
The big problem getting over the mountain passes in Colorado is how well the trailers are loaded.
If you have two trailers that weigh close to the same the back trailer is nothing but dead weight that works like an anchor, preventing you to go uphill.
But the biggest problem is when the trailers are loaded backwards and you have 2,000 or 3,000 lbs more weight on the tail of the lead trailer than in the nose. That is when you spin your single axle drive tires even with three railer chains.
The drivers that run from Grand Junction to Denver and back every night have 6 three axle trucks that go to the top seniority drivers, and then they use regular single axle trucks for the rest of the drivers. These guys go thru chains like there is no tomorrow.
