A blister on the tire sidewall is a raised area that looks like a bubble or bulge on the outer surface of the tire. It is typically caused by the separation of the tire's inner layers, which can be a result of manufacturing defects, impact damage, or overinflation. A blister can weaken the tire's structure and increase the risk of a blowout, so it is important to replace the tire if a blister is detected. Driving on a tire with a blister can be dangerous and should be avoided. **

It is possible for 2-year-old winter tires to develop bulges on the sidewall. This can occur due to a variety of factors such as improper storage, overinflation, or impact damage. It is important to regularly inspect your tires for any signs of bulging or damage, and to replace them if necessary to ensure safe driving conditions. Additionally, proper maintenance and storage of tires can help prevent bulges from developing. **

If the sidewall of the bicycle dynamo does not have a grip, you can try using a non-slip material such as rubber or silicone to create a makeshift grip. You can cut a small piece of the material and attach it to the sidewall using a strong adhesive. This will provide the necessary grip for you to repair the dynamo. Additionally, you can also use a rubber band or a piece of rubber tubing to wrap around the sidewall for better grip while repairing the dynamo. **
