Wheel Balancing
5. Wheel Balancing
A: ADJUSTMENT
NOTE:
Change the setting of wheel balancer to adhesive
type weight as adhesive type weight is adopted for
outside balance weight of 17-inch and 18-inch
wheel.
1) Remove the balance weights.
CAUTION:
• Be careful not to damage the wheel.
• Completely remove the two-sided tape of the
adhesive type weight from the wheel.
2) Using the wheel balancer, measure the wheel
balance.
3) Select a weight close to the value measured by
wheel balancer.
CAUTION:
Use SUBARU genuine balance weight.
4) Install the selected weight to the point designat-
ed by wheel balancer.
CAUTION:
• Remove grease from adhesive type weight
applying surface of wheel.
• Press the adhesive type weight by 25 N (2.5
kgf, 5.6 lbf) or more per 5 g (0.18 oz) for 2 sec-
onds at least to attain close contact.
• Make all amounts of the applied adhesive
type weight to be 100 g (3.53 oz) or less.

WHEEL AND TIRE SYSTEM
“T-type” Tire
6. “T-type” Tire
A: NOTE
“T-type” tire for temporary use is prepared as a
spare tire. (Except for KA, KS model)
CAUTION:
• Do not use a tire chain with the “T-type” tire.
Because of the smaller tire size, a tire chain will
not fit properly and will result in damage to the
vehicle and the tire.
• Do not drive at a speed greater than 100 km/h
(62 MPH).
• Drive as slowly as possible and avoid pass-
ing over bumps.
B: REPLACEMENT
Refer to “Steel Wheel” for installation procedure of
“T-type” tire. <Ref. to WT-5, REMOVAL, Steel
Wheel.>
CAUTION:
Replace with a conventional tire as soon as
possible since the “T-type” tire is only for tem-
porary use.
C: INSPECTION
1) Check the tire air pressure.
Specifications:
420 kPa (4.2 kgf/cm
2
, 60 psi)
2) Take the stones, glass, nails, etc. out of the
tread groove.
3) Check the tires for deformation, cracks, partial
wear or wear.
CAUTION:
Replace the tire with a new one if defective.
