twin wheel carrier

I have seen twin carriers around with kaymar stickers that carry 2 tyres- one on the inside of the carrier, the other on the outside- both tyres mounted on the same swing-out arm (4x tyres all up). I have only ever seen them carrying thin LT tyres- but it does the job it is made for. I have never seen them on sale though, so I am not sure if they are modified kaymars, or a standard item.

Dodgy - YES.

Legal - Probably not.

Something Positive - Ahhhhhh nup.

Tried the same idea od strapping tyres together on our caravan, it didn't last long and that was with a casing not a whole assembly.

I would be reluctant to place 2 tyre assemblies on a single carry point.

1. You will probably exceed the load limit for the spare wheel carrier.

2. You may cause damage to the Rear Door or hinges due to the extra weight.

We have a Prado which does not allow for the fitment of a replacement bumper and dual wheel carriers, although I would love to fit one. So we a left with the wheel on the roof rack. It is a pain as lifting it on and off can be a bit of a task, but it is that or have no extra spare.

dodgy.. i like it.

The original opposite lock twin wheel carriers had problems with the strength of the swing-out arms. There are a few people on this forum that have experienced the cracks forming on the arms. The ones made now have gussets in to strengthen the welds that failed before, and they are advertised at a 1-tonne load rating per arm.
Given the weight of a tyre, if you go making your car fly and land hard you are approaching this SWL limit. Even with a longer-than-standard high-lift jack hanging off the back of one of my spares, the extra weight still takes its toll on the bearings- they are showing slop now, and its only a year or so down the track.
Bung an extra tyre on an same arm, and you effectively triple the torque applied to the arm and bearings- a few small speedhumps and I reckon youd be looking for runaway tyres.

i strap just the casing on the spare at the back without any problems would have covered almost 20,000 klms that way.
The trick to stop the tyre sagging as you drive along is to bend a short length of 50mm x 5mm flat steel into an 's' shape. One end of the 's' goes over the spare on the car ( tight fit ) and the other end hooks under the lip of the case, than you only have totie the bottom of the tyre in works for me
can email a sketch if you need

Yea it's allot of money so might just stick with the roofrack
