Looking to get a set of wheels and tires for a 98 Camry. Nothing gaudy, but my question is how concerned should I be with matching up the overall diameter or the tire and wheel with a new set? How much will it throw my speedometer off and is it a big concern?

I have the formula to determine the overall tire diameter... it has 15'' stock wheels and if I get 18's with 225/40's theywould match the overall diameter to .4 of an inch... but I think 19's or 20's might look better on the car.

Any input from experience? This is my first time altering stock wheels on a vehicle.

Thanks
