My Ride: 325 CI
Question Will this Tire Combination Work?

Can anyone tell me if this is a good idea or not. I have a stock 325 CI Coupe with the factory sports package which includes 17x8 star spoke wheels, 225/45 R17 tires all around. I wish to upgrade to 18x 8.5 inch wheels, either ACS III or RD RD2 wheels. However, I do not want to lower my car or mess with the suspension in anyway. So, in order to eliminate the ugly looking wheel gap, I was thinking of installing 225/45 R18 tires on the front and 245/40 R18 tires on the rear. This combination would keep my tire sidewalls at 4.0(front) and 3.9(back), the same as the factory tires. However, my tire diameter will change to 26(front) and 25.7(rear), an increase of 1(front) and 0.7(rear). Im hoping that this increase in diameter will eliminate the wheel gap. Does anyone know if this will all work and whether or not I will have rubbing issues or if my ride quality will change. I do not want to have a loose ride. I welcome any suggestions you guys may have.

using tires with a higher profile will NOT reduce wheel well gap. In fact it would probably make you car look higher.

Reduction in wheel well gap = lowering the suspension.

I'm increasing Rim size

Shouldn't increasing my Rim size by 1 inch and keeping the same tire size eliminate that gap. Afterall, i am increasing the overall diameter of the wheel and tire together. For example, let's say my car was lowered. If I decided to put on 19" inch rims, I would rub simply because the diameter of the wheel is too big. But if I had 18" rims, I wouldn't rub. So, putting on 19" rims, because of the increase in overall diameter, would eliminate the wheel gap and cause me to rub. Right?

Again NO, you want to reduce wheel well gap you MUST lower your car increasing wheel and tire height won't do it.

By maintaining the same wheel and tire height and lowering slightly will no cause rubbing.

I had/have 235/40/18s and 235/35/19s on my car lowered on H&R race springs and never rubbed once.
