What cause "scallops" on all position tires on front axles?

[Jon]

I know from experience if you put scalloped tires from the steer to the tag the tag position will eat them up in a relatively short period of time. The best place for tires with that issue will be on the drive and over time the drive axle will get them wearing evenly.

I had one tire scallop on a bogey...in 100 miles at 110 psi...shocks are IMO, what caused it...and maybe age as the tire is close to out dated..

Brian I believe you driving to close to the Ocean, and that's why you are getting Scallops, little butter and white wine done.
