Wheel size

[69catguy]

Just checking to see what is standard rim size for all drum from car. It appears I have. 5 x 4.75. When I order new rims does the back spacing matter? Looking to order Holley rev classic series magnum. The size is 15x7. 5x4.75. 4 inch back space

You dont have a 5x4.75 bolt pattern.
B body is 5x5.
The Holley web site showed nothing that fits a 69 Catalina.
American Racing web site shows wheels that fit.
You can do 7" wide in front 8" in back.
The 15" size is a poor selection of modern tires, consider 17".

Are you sure about the 5inch bolt pattern. Seems when I measure from center to center on odds and even studs it measures 4.75

Look at the tire availability. Depending on your type of driving you can get summer only tires in 17" but not in 15". Even all season has more choices. Check tirerack.com

Can I put 15x8 with a 5inch backspace on back and front. Looking at the vision 521 nitro wheels.

decided to go with the gm style wheels with the rings and center caps from speedway motor. 15inch. 15 x 8 on back snd 15 x 7 on front. Thinking of the cooper cobra tires. Any suggestions on tire size for front and rear ?

Assuming your original tires were 225/75x14 maybe a 245/60x15 but you would have to measure clearance to be sure.
