I need tire help!

[spacepirate]

I'm looking to purchase some wheels today, ha! I have a 68 Camaro with a DSE front subframe. They recommend a 255/35/18 up front and 315/30/18 in the rear. The problem is that I can't find this tire combo with the exception of race/autocross only Toyo Proxies R888. They actually have a warning on their site about not using these in wet conditions and I plan on have this be a daily driver too. Do you guys have any suggestions?

I was told I could go up to a 9.5 front width but what size tire would that fit?
