My experience is just go to a good local tire installation place and have
them purchase and install. If you purchase them and have them shipped to
you, the shipping alone will off-set any savings you would get by finding a
good deal. You will also find that you will get better service from a shop
if you purchase from them. As far as shops, look for a good local
independent shop if you can. I DON'T recommend Sears, K-Mark, Costco or big
name shop that includes tire sales as only a part of their business.
Give them your budget and what you would like out of your tires, and let
them help you out. Steer away from ANY shop that says "X" brand is the best
tire no matter what you want it to do. Or.... "Those suck, get these..."
type of things. In general, stay as low a treadwear rating number as you can
afford. The lower the number, the softer the tire, and hence better
traction. Again, this is a general statement. Not ALL lower numbers will
perform better than higher number tires. My PS2's are 220 and found them to
be far better cornering tire than Goodyear Eagle F1 GS-D3's (rated at 280
treadwear). The Eagles DON'T like to turn, and don't hold a line nearly as
well, as they "creep" off line during hard cornering.
I just copied/paste this from a previous post to fobra. Not specific to your post, but should answer your questions
