Regal V8-307 5.0L (1986)
FIGURE 2 - TIRE ROTATION DIRECTIONS
A.
If only slight cupping is noticed, and the cross grooves in the tire's outside shoulder are still visible (See Figure 1), the tires should be rotated.
The modified "X" pattern should be used (See Figure 2). This method will best equalize wear after a few thousand miles.
B.
If the cupping or wear is severe, and/or the cross grooves in the outside shoulder are not visible, tire replacement may be necessary. Tire
Replacement, if required, will be made with the same brand and type tire as original equipment. These tires will be furnished on a "Direct
Bill" basis to the dealer. Replacement tires must be obtained directly from the tire company by calling the following toll-free number:
Firestone
-
(216) 379-7096 (Collect)
General
-
1-800-426-4889
Goodyear
-
1-800-TIRE-TEC
Uniroyal
-
Uniroyal - 1-800-231-5893
(Except Texas) 1-800-833-5906 (Texas)
Dealers must supply owner's name, VIN, mileage, dealer code, tire make, size and description (i.e., Whitewall, Brand Name, Etc).
A maximum of two tires per vehicle will be provided on a "one time only" basis at no charge to the customer for the first 12,000 miles or 12
months.
2.
Whenever tires are replaced or rotated, perform the following:
A.
On LeSabre, LeSabre and Electra Wagons, and Regals, front alignment must be measured. For best tire wear, reset toe to zero. Camber and
caster should be set to specification.
B.
On Rivieras, reset rear toe to Zero.
C.
On Centurys, install rear axle shim kit, Part No. 14094481, as explained in Service Bulletin 86-3-3, dated January, 1986. This will reduce
rear toe.
D.
IMPORTANT ON ALL VEHICLES To further help minimize tire wear, stress the importance of regular tire rotation to the owner. The
modified "X" pattern at 7,500 miles is recommended. Also, point out the importance of proper inflation pressure, as listed on the tire placard
on the driver's door edge.
3.
Old tires must be scrapped by drilling four (4) holes through the tire's serial number, located on the back sidewall.
Mount new tires with the yellow mark or orange label on the tire at the valve stem on the wheel. Balance and install on Non-drive axle positions.
Customer Reimbursement
Claims for customer reimbursement of previously paid repairs due to the described tire wear condition, accompanied by originals of paid receipts
verifying vehicle mileage, should be submitted to the Buick Zone Office. Vehicle mileage must be within the specified parameters to be eligible. Attach
