I looked this up in "The Radio Amateur's Handbook"

They refer to wheel noise and tire static as two distinct problems.

Here's what they have to say:

"Wheel noise produces a ragged-sounding pulse in the mobile receiver. This condition can be cured by installing static-collector springs between the spindle bolt of the wheel and the grease retaining cap. Insert springs of this kind are available at automotive supply stores."

"Tire static has a ragged sound too, and can be detected when driving on hard-surfaced highways. If the noise does not appear when driving on dirt roadsit will a sure indication that tire static exists. This problem can be resolved by putting antistatic powder inside each tire. This substance is available at auto stores, and comes supplied with an injector tool and instructions."

This verbage is found in The Radio Amateurs Handbook dating at least as far back as the early '50s. I have heard of this anti static powder before, but have never actually seen it in any auto supply store. There are references in some editions from the '50s to Chevrolet as a source for the described anti static powder, but I would be surprised if that were still true. Nowdays with VHF FM being the predominant automotive radio mode, noise issues like these are pretty much a moot point.
