I was skeptical of the Milestar tires, but after reading numerous reviews on Amazon and seeing near universal praise, I thought I'd try it via Walmart, because the tires could be shipped to the store and mounted locally. Aside from inventory issues – Walmart shipped 3 tires instead of 4 – and a 5 hour wait for installation at my chosen store (I picked up the tires and drove 30 minutes away and had immediate service) – the tires have matched expectations.
There is only a very subtle difference in handling on my 2004 RSX. The Milestars are very slightly softer – but the handling is still great. They were easier than the Michelins were new to balance. The Michelins maxed out weights to balance one of the tires originally, and near end of life, one of the Michelins had a bulge – and they lasted 40,000 miles less than the set before them.
Overall, the $550 savings by going with the Milestars vs Michelins was well worth the savings. I will, however, have to wait for Seattle's longest dry spell to end to see how they handle during the rainy season.
