Tire ?

I need new tires for my 2009 LT sedan (185 55 15 oem) What has everyone been replacing oem's with? I wanted the Michelin Harmony but not available in the size. Also, what other size tires can I go with?
Thanks

Read the tire tech area on tirerack.com. It will explain to you A LOT about tires and what the sizes mean. I cannot find the exact area that I am referring to or I would just post the direct link. But Tirerack is a good resource of knowledge. Looks like you could go to a 205/50 if you have room for the width.

i am looking to get a set of cooper cs4's I'm not sure if the come in the size you are looking for, but it's possible.

it would be easiest/cheapest to go to a 195/50r15. close enough in size and since its not almost a 3/4 inch wider than stock it will fit ob the rim nicely. Not sure harmony is a tire choice in that size. My favorite tire for the price so far has been my sunny 3800.. I paid next to nothing for them and they have been on over 10k miles (which is a long time for tires to last me).
