Rusty,
I have big tires on the back with deep rims. However, the tire size is the same diameter as the oringinal 16" 650. They are 15's now. I like the way the low end torque of the dodge 230 pulls at low speeds around town without shfting down a lot.
I have decided to just enjoy the car and not hassel with the gas miliage. The difference in the cost of gas is not a big deal, I drive it all the time.
i'll try to get some pics on here to show it.
Thanks, Jim
