Hi, I just noticed my tayar suddenly got a bulge... I changed this tayar last year around December so its still quite new... mileage probably about 20k only... its a Continental CC7 195/55R15...

Question is.. is this bulge concerning? will my tayar be at risk of bursting? or is it a normal thing and i don't have to worry too much about it?

I would bring to a tayar shop to check but just also asking here for opinion to cross check later with what the tayar shop tells me...

Oh and if I'm not mistaken this tayar got punctured before and was patched internally... not sure if that info has any relevancy though...

I thought about that but stupid me go and throw away the receipt already... don't think the tayar shop still willing to honor the warranty without the receipt proving that I changed my tayar in their shop...?
