Purchasing a '61 Catalina
 

I'm buying a '61 Catalina, and was wondering what size tires would work with the 15x7 inch Pontiac rally rim. I have a set of 275x60's for the rear that I would like to use. Looked on the search threads and didn't see any help.. Don't know what year 60's would be similar to the '61 .. thanks for any help.

Check the bolt pattern,61s are 5x5!Tom

Yeah, like to see what size tire it will fit within the rear fender.. Have a set of 15" 5x5 rally rims but not sure I will use them.

I would advise against a 275-60 on a 15X7 rim. Might be able to squeeze a 255 on there, a 235 will definitely fit. I have 15x7s on my 62 Catalina, I can crawl under this week and take pictures of clearance if you would like. There's not a lot of room on the quarter panel side with the rally wheels, a wheel with more backspace would help.
