One Last questions for me.

I can either run 245/40 18 on all 4
Or run 235/40 front 245/40 rear would there be any pluses or minuses for either way.

One big plus for me with 245 on all 4 is i can sum what rotate them. (directional) What do you think.
The tax man will be here soon to buy them for me..

I don't think it'll make much of a difference either way. I usually like a little bit smaller tire in the front. And on these old cars, I don't drive them enough to worry about rotation anyways. Or I can just have a buddy, de-mount and re-mount side to side, if they are directional tires.

I thought you were going with 255's in the rear?

cost prohibitive at this point
