Does anyone know the difference and have specifications for 122 /p1800 steel wheels?
P/N 670451 marked 4.5 x15;
P/N 668280 also marked 4.5 x 15
What is the difference between the 2/two wheels ?
What vehicles were they used for ?
thks

The 670451 wheels came on the 122 wagon.

The 668280 wheels came on the 1800S.

Both wheels have a 5 x 4 1/2" bolt pattern.

I never bothered to check, but the offset is probably a little different.

I do not have any of these wheels loose laying around, but do you know if the 220 wheel is heavier than the P1800 wheel ?

P/N 670451 marked 4.5 x15 = Wagon
P/N 668280 also marked 4.5 x 15 = 1800

I've not had them on the scales but I've read that the Wagon ones are a bit more heavy duty. Most of the vented Wagon ones have a safety bead and you can see that from the outside of the wheel as a ridge around the outside part of the rim. Some, I believe early, vented Wagon rims have no bead but are still stamped as 670451. I have a set of those on my Wagon here in the UK.

#670429 4" vented rims were fitted to all later saloons inc the 123GT.

Early "solid" wheels
#657838 4 1/2" 1800
#89991 4" Amazon saloon and PV
#662842 4 1/2" Amazon Wagon
#89735 size? Duett/P210

#670450 size? vented for Duett/P210 Difference to #670451 not known.

When rims gained the safety lip, they also got stamped with J or JJ.

Do you know if this applies to all manufacturers, or just Volvo. Referring to the J or JJ stamping here.

It was all cars, because it was a standard, much like imperial demensions remaining the standard, after Michelin's metric TRX system failed to take over.

Thanks for the great info.

Based on that, would it be safe to assume that 668280 would be appropriate for the 123GT? Or did they get something unique?
