Hi,

I bought 2 used tires and I noticed that they have a small bump on the inner side of the tire. One is bigger and the other is smaller. It's my first time seeing such a thing. Do you guys know why that is? I'm not sure if it's safe to drive...

Please see attached pictures below:

i would replace it, i had a smaller blister on my tire and replaced it
im no tire expert though

 

It is safe to replace

 

Now you know why they were selling the used tires. I suggest replacing them immediately with some new tires. Those are not safe.

 

Definitely needs to be replaced. After I had it completed I would go back to the used tire shop and get my money back
