Nexen Roadian HTX RH5 or Cooper Discoverer HT3

I bought Goodyear tires from a large online retailer and took them to a local installer. The tires were barely within limits of being round. Never could get them balanced well. No response for warranty. Have never purchased online again. Buying local pays dividends when you need assistance. The cost difference wasn't significant by the time you drive away with new tires, especially if you are spending time returning for a rebalance or replacement tires.
