THANK YOU FOR YOUR HELP|||You're an idiot if you put anything bigger on your car then intended by the manufactuer. For one, your gas mileage will get worse. Every ounce you add per rim is more work per rotation exponentially for the engine. More work for the engine means more stress on internals, oil, etc. AND its more work for your braking system, primarily for pads and rotors. They are rated to stop a certain amount of force. By adding more weight you are adding more stress to the brakes. You'll burn through them faster. Probably increases your stopping distance too. If you get in an accident it could be used against you. And there is probably 50 other reasons not to do it. My point is, don't do it.|||17 or 18 is the inside diameter of the tire so yes you will have to buy new tires and yes they are more money|||A lot more money, because of the larger non-standard size.





If they will even fit.
