I just looked up the tyre options on HJ. There are 2 x tyre codes for a ZX radial: QRR and QRA. QRR has load range ML, QRA load range HL. QRR wasn't available on any commercial vehicles, but QRA was available for utes & vans.
QRA suits the following in HJ (QRR is basically the same but not on utes or vans):
Belmont 6cyl sedan & wagon
Kingswood 6cyl sedan & wagon
HOLDEN 6cyl van and ute
Kingswood 6cyl ute
Premier 6cyl sedan and wagon
LS 6cyl
Statesman Deville
Belmont V8 sedan & wagon (except Belmont sedan with 308 and twin exhaust)
Kingswood V8 sedan & wagon (except Kingswood sedan with 308 and twin exhaust)
Premier V8 sedan & wagon (except Premier sedan with 308 and twin exhaust)
LS V8 (except 308 with twin exhaust)
HOLDEN V8 van and ute
Kingswood V8 ute
Unfortunately it doesn't suit GTS (in HJ anyway). This should be the same/similar for HQ and HX. When XX7 10cwt was introduced later in HJ it is quite possible the QRR tyre became available also on XX7 and XU4 so it could be that too.
These are not the base tyre for utes and vans though.
I'll have a look tonight but i'm pretty sure my HJ Premier had Michelin ZX when new as it was ordered with 6" rims but it only had single exhaust. I'm pretty sure the spare is still in the boot. I have a feeling it may have been QRR though as QRR is the sedan tyre. Can you have a look at it and see, if it turns out to be a QRR tyre i'll be real interested, primarily as I am about to put GTS rims on the Premier and this would include a spare. Would be nice to put an original, untouched spare tyre on the spare wheel!
