Can anyone tell me or point me to a website that can help me with tire sizing for a 67 Chevy II. It's for a friend. He's running 15x7 rally's and wanted to know how big a tire he could run in front and back. He currently has 235/70's and they rub. Any help? Thanks.

Try Car Crafts web page and search for 66 67 nova. I believe they did a whole issue sometime back of early novas with exactly the info your looking for. A buddy of mine was looking for the same info and found it there.
