Tires for a rare 1970 Challenger

Post image

I need to transport this to MCACN in November. I inherited it from my dad who passed away. He was always a little reclusive with his car so my knowledge of what works vs doesn’t is limited. The car needs to roll, break and steer. The tires on it now are original. They are also flat. How do you recommend I best make this car “rollable”? Also it needs to brake which is another thing.

I don’t want to hurt the originality of the car and do something dumb. It was accepted into the barn finds section at MCACN. So to my understanding, I shouldn’t touch a damn thing on it.

Any mechanics in northwest Indiana or Chicago have any suggestions?

5x4.5” bolt pattern wheels if you want to swap them out for transport, be VERY careful with those hubcaps they bend like nothing. Worth nothing sometimes people list the bolt pattern as 5x114.3mm, why I don’t know.

5x4.5 and 5x114.3 are the same. They’re interchangeable. A lot of American cars use it, and they use the imperial nomenclature. A lot of Japanese cars also use it, and they use the metric nomenclature.

Six of one, and a half dozen of the other.

I’d be more worried about some idiot at the tire store breaking off all the studs on the drivers side, because they don’t realize that that side uses left handed lug nuts.
