Motorcycle Tire Cupping

So, what this motorcycle tire cupping is? Like we have mentioned above that it’s uneven tire wear and occurs in patches from three to four inches across. This kind of tire wear is noticeable, but it gets easily confused with other tire wear types.

The problem with tire cupping is it causes inconsistent contact. The tread of these tires stays in connection with the road at all times. If these tires get cupped, the tire contact becomes erratic and creates patches with different high and low contact points. It can significantly reduce traction and might result in a loss of control over your vehicle.

Causes of Motorcycle Tire Cupping

You might be thinking about the cause of this uneven tire wear. Is it improper air pressure, bad suspension, misaligned tires, or something else? The thing is that various factors might cause the issue of motorcycle tire cupping.

If you are thinking about “How do I fix motorcycle tire cupping,” you need to divert your attention towards the causes and try to eliminate these. It will help you to avoid any inconveniences and unwanted costs as well.

Motorcycle tire cupping can occur due to suspension problems. You need to fix these issues to avoid any extra castor repair. Some of the common problems associated with tire cupping are:

●     Misaligned tires

Misaligned tires

The most common cause of tire cupping is misaligned tires, resulting in uneven contact with the road. Your tires don’t roll straight and wear unevenly. Due to these uneven stresses that the road conditions inflict on your tire, begin to show tire cupping signs. There might be a sawtooth-wearing pattern right at the edges of your tread. This type of weaning is referred to as heel to wear in engineering terms.

●     Worn out shocks and suspension

Old shocks and suspension

Another common reason for tire cupping is worn-out shocks and suspension. Different suspension components, including struts, shock absorbers, and bushings, tend to wear out as you travel miles on your bike.

This might result in a tire that cannot roll smoothly on the road but begins to bounce slightly. With this bouncing, uneven tire pressure points occur, and it ultimately results in tire cupping.

●     Unbalanced tires

And then, there is the issue of unbalanced tires due to an uneven distribution of weight across the tire circumference. If this weight distribution is severely uneven, then an off-balance condition might cause different tread sections to contact the road with different pressure and force. With uneven force and exertions of the contact, points wear uneven, resulting in erratic tread wear or tire cupping.

●     Low-quality/cheap tires

Different tires have different qualities. Some manufacturers use lower quality materials in the construction of their tires. They might use steel belts to provide less tread support, or they might have low-quality rubber. Such tires are more prone to cupping if they are on a vehicle with worn-out suspensions and imperfect wheel balance.

Signs of Motorcycle Tire Cupping

When you see vibration through your bike’s handlebar, the uneven wear is in the front wheel. Vibration in the seat means the rear wheel has uneven tire wear. If you notice shaking and vibration through the handlebar and the seat, both your tires are uneven.

●     Tire noise

Tire noise

Another sign you will notice when dealing with tire cupping is getting a lot of tire noise. The tires are very noisy, particularly when you are going at those highway speeds. If you notice your tire speed is increasing, you need to get them examined by a professional right away.
