我来告诉你如何省钱。

你的选择很多：
1）。你可以去WalMart, Costco, Sears, America Tires, Big O Tires 去换轮胎。比较哪一家比较便宜。
2）。也是我认为最便宜的方法：到一个网上的网站www.tirebuyer.com 去买轮胎，非常便宜的，有的轮胎只有Costco的一半价，在网上买好后ask tirebuyer to deliver (it is free delivery) to your local Big O Tires for installation ( the installation charge is very reasonable and cheap, and Big O Tires is very popular and you can find it everywhere:-)). In this way, the total cost may be much less than the cost you spend in other places.
