In terms of wheel size/tire size/then tire width. Both axles please!
14x5 to 15x7 was the range for factory rims. Fronts and rears were same.
The six cylinder and 318 V8 models used 14 X 5 inch wheels. Big block cars came with 14 X 6 inch wheels with 15 X 7 optional. The 340 T/A and 426 hemi cars came with the plain steel 15 X 7
The six cylinder and 318's were built with 14x5 1/2 steel wheels and E78 tires, the big block wedge cars, 14x6 steel wheels with F70 tires and all the Hemis, 15x7 wheels with F60 tires. The optional Rallye wheels could be had in 14x5 1/2, 14x6 and 15x7, the optional five spoke road wheel could only be had in 14x6. All front disc brake cars and 340 built cars required 15 inch wheels for caliper clearance. The Challenger T/A was unique in that the front tire size was E60 and the rear G60, both 15 inches. This information is for 1970 models only. I found and purchased in the mid '80's a set of 15 x 6 1/2 Rallye wheels that supposedly came off a '78 Chrysler Cordova.
