70 Steel Wheel Codes
My 70 GTO came with steel wheels and deluxe wheel covers. It has KT Rally IIs on it now. I'm planning on going to steel wheels and poverty caps (because those wheel covers are...not my taste]. What's the correct code for these 14x6 steelies?
This says the 1970 code is "NA," but every other year is "HF." I haven't seen any "NA" steelies available. I'm thinking "NA" means "Not available for us to find," maybe? Everyone's favorite Pontiac Wheel Applications doesn't seem to remember that 14x6 steelies were a thing. Did 70 GTOs get HF steelies? Last edited by goatboy1970; 01-16-2023 at 04:01 PM. |

I want to help, but to date I haven't compiled ALL steel wheel codes, becasue that list would get huge;
This is what I can offer; I have a 1970 Pontiac 14x6" steel wheel code of 'AM' as being for 1970-1972 Firebirds. I believe that the Pontiac A-bodies did share wheels with the F-body; Although unlike the 1970 A-body, any Firebird with an F series tire received a 7" wide wheel (I believe that A-bodies could come with F & G series tires, but they retained the 6" wide wheel). I even have in my yard what appears to be an original 1972 A-body wheel that is a G-series tire on a 5" wide wheel!? (code DD). My notes suggest that the KT 14x6" Rally II was a 1972 A-body wheel.

KT is definitely the 72 Rally IIs. 70 would be JT.
AM is a totally new one to me. I'll look into those. I've also considered the 14x7s from the Firebirds. Is that CL code? |

70 & 71 Pontiac A-body used the HF code 14x6 wheel on GTO's & V8 A-body's. Im not sure how much longer this code was used, but I am watching when in old yards.
'70 Pontiac A-body's did NOT use the same coded wheels as the new 2nd Gen F-body's. '70 Formulas w 14" Rally II option received 14x7 JS's. '70 Pontiac A-body's were not built with 14x7's. Instead, the GP's, which used the same disc spindle & rotor as A-body's, when equip with Rally II wheel, received the '70 usage JM coded rallyII's. The JM rally II was first introduced early Summer of '69 Firebirds & was used til the end of '69 Bird production. In the '71 model year, the KS coded 14x7 rally II was introduced for GrandPrix & Formula usage, this code lasted for at least 3 more model years. During the Fall of 70 UAW strike, Pontiac Engineering consolidated several things. One was the prev 70.5-early 71 A-body only 14x6 rally II usage wheel (code JT) was replaced by the KU. The KU was also shared as optional on the Ventura II (X-body). In '72, the KU wheel continued on as the optional 14x6 wheel on V8 Venturas, but the KT coded 14x6 went on A-body's. Last, if you collect info on '71 Pontiac A-body's, like I have one w the GT-37 Survey, one will notice the wheel box on '71 Pontiac plant build sheets shows JT as the 14x6 rally II wheel code for many months after Motorwheel began producing the KU 14x6 wheel, & those KU wheels began being installed at all A-body assembly plants.

Will look later this week at what code 14x6 steel wheel I have in the trunk of a base 350 4speed Firebird in back of my shop. In the wheel stacks, I have an AU coded 14x6, am also trying to figure what it came off of. BTW, your best source of original wheel codes is not on that silly site

My '70 Tempest (400 2-bbl/TH400) and '70 LeMans (350 2-bbl/M-20 4-speed) both have HF 14x6 steel wheels. I'm quite sure the GTO's also came with them (HF code) too if Rally II's weren't ordered.

This is a great discussion, I’m going to refer to it tomorrow and update my notes on Rally II and steel wheel codes.

OPH - your knowledge is again impressive and interesting. Thanks.
Forgive me but where are these codes stamped? I'm just curious if my 70 LeMans has its original steel wheels. If on the outside, I'll look for the codes. Sounds like HF is expected. |

typically on the outside, beside the valve stem

HF will be stamped to the right side of the valve stem.
the 14x6 HF's I have to run on my HO T-37 Coupe were sourced from a very early model '71 Pontiac GTO. They were made by Kelsey Hayes. Will get a pic tomorrow.

Amazing pics. Thanks for sharing. That's exactly what mine rolled out of the factory with. Going to do the white stripe tires, but going to switch the wheel covers.

This thread is amazing. Love this community. Now...any recommendations for where I can find a set of 5 HFs with good date codes?

I looked and find my 70 LeMans wheels are XE code. I don't know if they are original but have no reason to believe they were changed.

Yeah, I've talked to a couple of "concourse restoration" guys and they have also said 70 is XE code. Looks like I'm hunting for those now. Thanks for the pics.

Can anyone explain for me the HF vs XE 14x6" steel wheels that both seem to be purported in this thread as being for a 1970 GTO?
(I am currently adding info from this thread to my wordpad file on steel wheels) In my 14x6" steel wheel section, I moved the HF & XE wheels up, and have a description for them, but the following codes are ones I have noted as not currently having any application information: CC, CZ, EM, EZ, FC, FM, HG, HH, HK, JJ, MH, R, XF(*), XJ, YB, Z6 * = I figured this was a typo on someone's part, and figured maybe the person who wrote this as a 14x6" code, meant to write XE. The 14x7" steel wheels I have identified on my list are XT, IF, CL, EM, UC TB (I have examples of all but the first one); I have the following codes as possible 14x7" wheels with no application information: XG, JZ Quote:
I have noted that there was a UA coded 14x6" steel wheel, I have written that this code was used on was 1975+ F-body.

I have been digging a little deeper and I may have come across something useful (at least to me) in explaining the HF vs XE wheels:

What's ".50 offset" ?? Your reference describes "primed" XE wheels. I guess that makes sense for replacements but suggests any XE wheel has non-factory paint? |
