Rims are not damaged but very old, I think they are stock, model is 1999. A few days back I went for wheel balance, the guy balancing wheels told me to replace them, according to him they have lost strength and may break in near future. Now, how I decided he might be true? Firstly, it is a reputable tyre repair shop, I have been getting my tyres changed/fixed by it since a long time, secondly, it doesn't sell/purchase rims so replacing my rims won't benefit him.
