What is the best tire for a 2001 BMW 325Ci that has good traction, but is also good in the rain. I live in Florida, so, I need something with good traction and good wet traction. Thanks!

Good touring/all weather tires are personal preference. Check out Tire Rack, they have everything and can help ya out with correct sizing. Personally, I'm running Toyo Proxes on my E46 325i, and haven't had any problems with them.
