Flashcards

Tire Mounting Safety

New tires need time to fully seat on the wheel, and sudden acceleration can displace them.

Sticker Alignment (Valve Stem)

Matching the sticker alignment with the valve stem during tire mounting is generally advisable for proper fit and positioning.

Initial Driving Speed

Low speed driving (less than 50 mph) initially after mounting is often recommended to ensure a good tire-wheel bond during the initial stages of tire mounting.
