Tire Mounting Procedures

For the proper mounting of Yokohama tires, be sure to observe some basic precautions:
  • Wheel is securely seated on the hub face.
  • All lugs have proper torque.
  • There is no buildup of dirt between the hub & wheel.
  • The wheel is not bent.
  • Both tire beads are securely seated on the rim.

Custom or Alloy Wheels

While custom or alloy wheels require an increased level of care over steel wheels, it is vitally important that each customer receives the highest level of service. There are several key points to note when mounting Yokohama tires. Following these basic precautions not only yields consistent results, but satisfied customers - & that translates into return business & new referrals.

 

Avoid scratching or bending alloy wheels during installation

These wheels are manufactured with extremely soft metals with a greater sensitivity to scratching & distortion under pressure. Modern tire machines apply equal pressure to both top & bottom beads with no pressure on the wheel itself. A pad on the base of the mounting machine protects chrome-plated, painted or machined wheels from scratches & damage.

 

During the mounting process, proper lubrication is a must

Lubricate both top & bottom beads with an approved tire lubricant. If the beads do not seat at 40 psi, break the entire assembly down & re-lubricate the bead areas.

 
Observe match-mounting procedures
Proper tire & wheel assembly balancing is important from a vehicle safety standpoint. In high-speed driving, improperly balanced tire/wheel assemblies will cause a vehicle to lose stability & not operate in a safe & comfortable manner. Improperly balanced tire/wheel assemblies also cause abnormal treadwear patterns.

To facilitate proper balancing, Yokohama places red & yellow marks on the sidewalls of its tires to enable the best possible match-mounting of the tire/wheel assembly. There are two methods of match-mounting Yokohama tires to wheel assemblies using these red or yellow marks:

 
  • Uniformity (red mark)
  • Weight (yellow mark)

Warning: Improper mounting, underinflation, overloading or tire damage may result in tire failure, which may lead to serious injury. Tire & rim sizes must correspond for proper fit & application. Never exceed 40 psi to seat beads.

Warning: Tire changing can be dangerous, & should be done only by trained persons using proper tools & procedures established by the Rubber Manufacturers Association. Failure to comply with proper procedures may result in incorrect positioning of the tire, tube, or wheel assembly, causing the assembly to burst with explosive force sufficient to cause serious physical injury or death. Never mount or use damaged tires, tubes, or wheel assemblies.

 

Proper Installation & Spacers
With some custom fitments, it is necessary to use spacers in order to achieve proper clearances. Whenever the assembly comes into contact with inner fender members, brake calipers or ball joints, consult the wheel manufacturer for recommendations on the proper use of spacers.

Spacers are sometimes necessary when wheels of the proper offset are not available. However, there are some drawbacks to their use:

 
  • Spacers are made in various quality grades. Some spacers may not be able to withst& the forces generated by aggressive or competitive vehicle use.
  • Spacers that use a generic or slotted pattern (for use on a variety of hub patterns) may make proper location of the assembly very difficult.
  • Spacers may necessitate longer lug bolts.
Special Considerations for Light Truck Applications
Because light trucks dem& special load-capacity considerations, we've compiled a few rules that should be observed:

Using passenger tires on light trucks
Using passenger car tires on light trucks should be approached with caution. The varied service that a light truck undergoes means that the rated load-carrying capacity of a passenger car tire used on it is reduced. When referencing a passenger car tire for light truck use, decrease the load specification according to the following formula:

This formula results in a reduced load-carrying capacity equaling approximately 91% of the rated specification of the passenger tire.

 
Dual Tire Applications
 
  • Matching dual tire specifications: Maximum allowable difference in overall tire diameter between a tire & its dual mate is 1/4". Maximum difference in circumference is 3/4".
  • Spacing: Minimum dual tire spacing is necessary for optimum performance. Consult tire or vehicle literature for recommendation.
  • Using chains: Take care to allow proper clearance between loaded tires to avoid damage from chains.

Warning: Passenger Tires Mounted on Light Trucks: Yokohama Tire Corporation's policy provides warranty coverage for all light trucks, minivans or like designs that had Yokohama passenger tires installed as original equipment by the vehicle manufacturer when the Yokohama replacement tire is the same size, ply & range/load index, & speed rating (if applicable) of the originally installed tire. The replacement tire must also have the same classification of tread design, i.e., rib, mud snow, all-season, etc., as the original tire. Vehicle operation must also be limited to personal travel & not commercial operation of any sort. Vehicle design and/or operation other than described above will be dutifully denied coverage under all terms of the Yokohama Standard Limited Warranty for Passenger Tires.

Warning: To avoid serious hazards, you must reinflate tires to specified minimum inflation pressure when used for highway service.
