Ballast Ballast in tires - problem

[Racer71]

You're doesn't have to freeze for this to happen. You didn't say how cold. The ballast could get "thick or slushy" when cold and not flow to the bottom of the tire as quickly as it is rotating. You may feel this even at 50 RPM tire speed.

You guys were right the tires were just flat spotted. We had a few night when it was -17 F. It is a little warmer now. Anyway I drove it a bit today and it seems to be better. Then I put it in the high range at a about 2,000 rpm in 2WD and it drove it down the road and it was just fine.

The substance is the tires is a nasty black substance - rimguard which is made from beet juice?

A friend of mine suggested that I put some plywood down where the reat tires are to reduce the flat spotting. Has anyone tried that?

Plywood is just as flat as the ground or floor Don't see where it would make a difference.

It wasn't flatness that was the issue - a little insulation from the cold concrete.
