I just bought a car with 15x7 Olds rally wheels. The lug pattern is 5x4.75. They are solid chrome. I need to know any and all Oldsmobiles that these will fit, because I will be selling them soon. What is the name that Olds people give these wheels.Is it rally I,II,orIII .I've attached a photo of what they look like. Any help would be greatly appreciated!

 

They'll fit any Olds with the 5 x 4.75" bolt circle. That's any 64-88 Cutlass, 73-79 Omega, the 64-66 Jetstar 88, and some 77-85 Delta 88s. The 77-up B-body cars came with either 4.75" or 5" bolt circles, depending on whether the car had HD suspension and brakes or not. Ninety Eights and Custom Cruisers, for example, all had the 5" bolt circle.

 

Joe, did those B bodies with the HD suspension have the 5" bolt circle? I have found that most of those 77-85 Deltas have the bigger bolt circle. At least that is my experience.

 

77-85 cars have 5 x 4.75'' same as the Cutlass
There ARE exceptions though.
Some of the wagons have the 5 on 5
and some of the sedans had upgraded 11.5'' brake drums which also had a 5 on 5 I believe.

Also it has been 30 years since then and many 5 on 5 axles have found their way onto these cars.

This fellow is doing the world a service by documenting the cars he works on.

Or you could get a simple gauge for under 10 bucks

 

I've got one like this. Ebay, about 6 bucks. I think the guy showed the back side on this one. Mine has numbers.

Actually, ALL of the wagons had 5 x 5. All 98s had 5 x 5. All taxi/police/HD brake cars had 5 x 5. The HD brakes are the 11.75" front rotors and 11 x 2" rear drums. Lesser B-bodies came with 10.75" front rotors and 9.5 x 2 rear drums.

 

I have owned all lesser B-bodys then
All 4 of mine were the small disc/drum setup
How common is the HD option?

 

Thanks for all your help guys! Much appreciated! I actually baught a 1970 Pontiac Lemans with those wheels on it. When I first looked at them I thought" Those rally wheels look like Olds Wheels.I didn't know Pontiac made wheels like that". Well after a little research,I find out, Pontiac never did make them they are Olds wheels! I will be replacing them with Pontiac wheels soon. Heres a picture of the car with the wheels They actually look pretty nice.

 

Nice clean looking Poncho! Those wheels do look good. Maybe you could find some of those wheels they put on the TA's, they look kind of like a honey comb design. That would be nice.

 

That is a cool car! The wheels are definitely AWSOME!
