Completer wear of tread surface -(creating an unsafe tire ! )
Overinflation.
Friction.
4/32" on the front tires and 2/32" on the rear tires.
Tires should have at least 2/32 of an inch of visible tread for safe driving, although 4/32 of an inch is recommended for better traction, especially in wet conditions. You can use a tread depth gauge or the penny test—placing a penny in the tread with Lincoln's head down; if you can see his entire head, it's time to replace the tires. Regularly checking tread depth helps ensure optimal performance and safety on the road.
Tires have molded indicators called "wear bars." If these are visible across the tread pattern, your tires need to be replaced.
Agressive tread, bad alignment
Tires must have a visible tread depth of at least 1/16 of an inch to ensure proper traction and safety on the road. Adequate tread depth helps channel water away from the tire, reducing the risk of hydroplaning and improving grip in various weather conditions. Regularly checking tire tread is essential for vehicle performance and safety. If the tread is worn down to less than this minimum, it's time to consider replacing the tires.
A penny can be used to measure for safe tread depth on your car tires. Hold the penny upside-down in a tread groove. If the top of Lincoln's head is visible above the tread wall, the tires are completely worn out, and need to be replaced, pronto.
More than narrow tread tires.
Poorly inflated tyres and unbalanced wheels and tracking.
they said mine did this because my tires were not stock and were bigger then recommended
Turning on a bicycle is different than in a car. When you turn on a bicycle you lean the entire bike to the side. This causes the sides of the tires to contact the pavement. The tread on the sides of the tires is there for this exact reason. Without it, you would probably skid out when you try to turn.
