Nice screen name
Any wheel of the same size will fit if it has the same offset and lug pattern. Larger size wheels will fit up to a certain point then they start rubbing stuff.
Some Camry guys put Lex IS300 wheels on. I know a guy with a 98+ Corolla with 2001 Celica wheels.
Unless you really want a particular toyota wheel for the look, you can just go to the aftermarket to find rims of all prices and styles. Check out
www.Tirerack.com they have a wheel desicion guide where you can look at a pic of your car and see what they look like.
Do you want a bigger steel wheel, or an alloy wheel or what?
