hey guys, the rear passenger tires on mums car had 2 punctures and as they are about 5cm to each other apparently its not safe to repair it. is this a legit claim?

so the guys at the shop suggested replacing tires, also due to the fact that they are 4 year old tires, even when they have 50%+ meat left (car only driven to work about 2 km from home). again is this a legit claim?

i've never had this problem as i often buy new tires for my wheels, and ive owned 2 cars over the 3 years. never thought old tires could rot over time. you learn something new everyday.

cheers
