Tire size?

[BJDEALER]

ok im on my way to the tire shop tomorrow. I need some tires for the rear on my 66 cuda. I have recently installed an 8 1/4 rear out of a 74 dart. I have stock leafs. I have a set of 4 16X8 inch billet specialty wheels with 4 inch backspace. My question is what size tire should I have them mount on one of the wheels to mock on the rear? I have 195/50/16 on the front. This is just to get the right size for the back. If I could get an answer tonight I would appreciate it. Thanks in advance.

Did some research tonight and found out that a 195 tire will not fit on an 8 inch rim. I guess this means my rims are 7 inch. Does that make a difference on the size tire I can use?

Was thinking of doing 225 60 16 to mock up what do you guys think?

225 60 16 should work, most clearance issues with early A's are with the upper outer wheel house area.(check both sides as manufacturing tolarances from Ma Mopar vary) a 7'' rim with 4'' backspace will be close. Factory mopar wheels in 7'' are 4 1/4'' and give you a little more room to the outer side.
