Can anyone help me with the load rating for 15" alloy rims from a 2008 Hilux and 15" steel rims from an early 80 series. I want to use either for my van. The LC rims have correct offset. Not sure yet if the Hilux will fit as bigger offset. Have to check room behind wheel on van.

The Hilux was available with steel or alloy rims so the alloys one would think would have a similar rating as the steels. The max axle load I could see for the Hilux quickly surfing the net was a rear axle load of 1600KG, therefore one would expect the wheels can handle 800KG ok. What the max rating is though have no idea.

Twinkles, you would have to contact Toyota and speak to their engineering dept to acquire the wheel load rating of either of the wheels.

By law, all rims are supposed to be marked with load ratings - but I've rarely seen it.

Clause 8 of the "Australian Standards 1638 Motor Vehicle - Light alloy Road Wheels", says -

MARKINGS; (this clause) requires that Light alloy road wheels shall be legibly and durably marked as follows:
(a) In a position which is readily visible when the wheel is correctly installed on the vehicle and without removing the tyre. The marking shall include the following details:
(i) The manufacturer’s name or trademark identification.
(ii) The wheel size.
(iii) The offset value.
(iv) The maximum wheel loading for which the wheel is designed.
(b) Anywhere on the wheel. The production period identification, in sufficient detail, shall be marked anywhere on the wheel at a convenient position, to enable the tracing of the wheel to alloy melt analysis and heat treatment records, i.e. batch/year.
The marking shall be cast into the wheel, or made by any other permanent method.

For interests sake, a 16x7 Mullins/CSA alloy rim to fit the Hilux (6 stud - 139.7mm PCD), with 30mm positive offset, is rated at 1150kgs.

This is well below the load rating for many of the tyres you could fit to this 16" rim. You can get up to 1850kg load rating on some the heaviest-rated 16" tyres.

As a result, rims are often the weakest link when it comes to tyres and rims - and it can lead to this ....

I found something the other day, can't remember where it was but it stated all non OEM rims should be marked with load rating etc.

I have asked a similar question on LCOOL about the load rating of 200 series mags, which have no load rating stamped on them. Neither do the steel ones.
The only usable guestimate was to look at the load rating on the OEM tyres and go with that.

Yep, had a look too, seems after market rims are around 1150-1250 rating.

ROH used to make an "Impact" mag for the 100 Series and when I contacted ROH on the load rating, they quoted 1250kg. I can't see the OEMs being any less.

Those 15" chromies on the 60 and early 80 series were never stamped with a rating. Nobody was bothered by that back then.
But if you want a good rating on a wheel for a caravan, the minespec wheels such as those listed by CSA (Ranger steel wheels) are rated at 1500kgs, and there are also a lot of caravan alloys rated at 1450kgs or higher available from MPC or Primal in Melbourne.
