Like you say, uniroyals used to be a top brand and we sold a lot but we currently have two sets on the shelf waiting to go back to uniroyal with complaints. They have both stepped and got very noisy. We are 99% sure uniroyal will send them back and say nothing wrong with them and to be fair, one set has already had plenty of wear out of them, but the customer is always right! Seems to be they are just so soft in the side wall.
