How Did I Get A Bulge In My Tire
A bulge in the tire can happen due to:
- Buying cheap tires
- Older tires (out of date)
- Damage from potholes and nails
- Rough road abuse
- Repaired tires
- Improper tire installation
Bulges are created by broken belts inside the tire plies, and/or by air that's forced under the different plies (From things like running over nails) which no longer lets the tire keep its form, (rubber stretches, steel doesn't) Which causes the tire to form a bulge. The bead of the tire (which seals the tire around the rim) can get torn or damaged during your tire's installation process which can also create a bulge in the tire.

Can I Drive With A Bulge In My Tire?
No, to do so, would put your life and anyone else's riding with you, at risk of death or injury. A bulge in your tire is a clear warning sign that your tire is about to have a blowout. Blowouts are the cause of many accidents resulting in death and injury. Driving should never be attempted or considered if you have a tire bulge on the tire wall of the tire(s) or on the tread itself.
Tire Safety Check
Your tires are the only thing between you and the road in most circumstances. It's important that if you buy a used vehicle or use a donut that has been sitting or stored for long periods of time that you check the tire(s) thoroughly for any signs of aging like dry rot (cracks in the surface) and bulges on the wall or tread along with proper inflation.
Find The Manufacturer Date
To tell if your tire is old or out of date check the date stamp located on one side or the other of your tire's wall. Depending on what way your tire was installed. You may have to take the tire off if you're unable to go under to examine behind the tire for the date.
Always use proper tires to stay safe driving and replace damaged tires.
