Make sure you check the tire date. Here is what the date stamp should look like date stamp
. It will be a 4 digit number such as "1510" is the 15th week of 2010.
A month ago I went for tires for my tow vehicle. The tires they had in stock were 0709 meaning 7th week of 2009. That was too old, so they ordered new Dunlop's from the warehouse with a better date (1510). My parents also bought tires for their toad a few weeks back. I reminded them to check the date before they install them. Well, they only asked the person who installed the tires if "they were a good date". I checked a few days later and the tires they put on were 3-1/2 years old (1307).
