You said the "A" word!!!
Unless you enjoy paying double for some tires,
you might want to check out local tire dealers. They have some tires that are comparable in price to stateside. Example- 4 Kumho Supra... P275 ZR40/17 installed, for under 450 eur (last year
). AAFES wanted triple that amount. If you can't find something decent around home, check out
http://www.tirerack.com or
http://www.discounttiredirect.com I have dealt with both MANY times. Keep in mind that discount tire may seem more expensive at first, but the shipping is free. Just compare the total price between the two. I just ordered two tires from the tirerack and they were sitting in the mail room in 4 days. (I paid a little bit extra for priority mail)
