Tire failure

3 years ago
I bought 2 of these rims and tires, inflated to proper psi, and both tires failed in under 200 miles. There is no sign of damage to the tread or sidewall, except where the bead came off the rim. I filled out the complaint through the online customer service and have gotten no response.

No, I do not recommend this product.

They work fine as of now only a few days in, only time will tell whether or not there is premature cracking like the older ones.

Yes, I recommend this product.
