SUBJECT:
IRREGULAR TIRE WEAR
MODELS AFFECTED: 1985-1986 FLEETWOOD BROUGHAM AND 1985 ELDORADO AND SEVILLE WITH ALL SEASON TIRES
This bulletin supersedes Serviceman Bulletin T-86-49, Group 3E, which should be destroyed. The labor operation originally listed as T6149 has been
changed to T6151.
Condition
Some 1985-1986 Fleetwood Broughams and 1985 Eldorados and Sevilles may experience irregular tire wear on non-drive axles with original equipment

tire. If allowed to continue, premature wear of tread may occur.

will also exaggerate this condition.
Service Procedure
Tire wear should be inspected:
