tires

[Don Bradner]

I replaced my steers with 315/80 XZA-2 a couple of months ago, and just hit the
road yesterday.

With 12Rs I had to run at least 115 on a 120-lb rated tire, and they would run
as high as 140 down the road (Pressure Pro reporting). With the 315/80 I set
them at 105 to carry the same weight on a 130-lb rated tire, and the highest I
saw yesterday was 124 running in 100-degree temps at 60mph. Ride when hitting
bumps much better.

I will be replacing the drivers next year, and will stay with 12R, XZE*. Shane
runs 315/80 on his drivers also, but has to run them at high pressure to keep
separation with 8.25-inch rims. I don't see any reason to do that, as 90psi on
the 12R is correct for my weight.

Tags get replaced with rotated steers, so in a couple of years I will have
315/80 on the tags. Again not needed, but not a problem.

My preference is to not have different-age tires on the drivers, so for me the
rotation is 2-4-2-2-4-2-2-4 rather than straight 2-2-2-2.
