This is a word of warning to any 80 Series owner with a trailer who may be thinking of upgrading to the 100 Series. On a recent trip to the Kimberley in my 80 Series, I met a tour operator in a 100 Series who was really peeved that Toyota had changed from 6-stud wheels in the 80 Series to 5-stud wheels for the 100 Series. This guy's trailers all had 6-stud wheels to be compatible with his 80 Series but when he upgraded to the 100 Series he had to get new axles and new wheels for his trailers to maintain compatibility - he said it cost him over $1,000 per axle. Anyone know why Toyota would do that - other than the obvious ($)?

They say it gives better clamping pressure (not that landcruiser wheels were ever known to fall off) But I think it has more to do with saving money by getting rid of 4 studs and nuts and maybe a bit of weight.

More to the point it is Toyotas own PCD so they can extract more $$$ out of you if you need replacement rims. As for "more clamping pressure" I don't see how, with one less stud clamping down at a lesser PCD this would increase the load per stud in tension during turns. I guess if push comes to shove they could always share the wheels from their other 5-stud four wheel drive... the RAV4

The 100 series studs are bigger.

It also depends on the thread pitch and depth, may be a thick stud with a fine shallow thread. Notwithstanding the extra stresses imposed by a 2 tonne vehicle on a 5-stud PCD that appears to be 10-15 mm smaller than the 6-stud would, during cornering, have to taken seriously. Sounds a bit like "+5% safety margin" engineering, I guess time will tell how it copes with the "+10%" that the Australian outback can serve up.

The only other 5-stud, 2 tonne plus vehicles I can think of are the Landrover/Rangerover and the Mercedes Gelanderwagen, both of whom have substantially larger PCD than the Toyota. The Toyota PCD is the same as they use in their passenger vehicles, Camry, Lexus etc., and I think the change was more influenced by cost cutting (cross-platform standardisation) than any real improvement in technology.

Further to other posts, The LC100 5-studs HAVE BEEN BREAKING STUDS (apparently acknowledged by Toyota) according to 4x4 Australia magazine (Prado review). That is why the new Prado RETAINS THE 6-stud pattern.

Toyota tough? yeah right......

$1000 per axle , man thats one expensive trailer !

Don't the trailer companies sell aftermarket wheel hubs to suit the existing trailer axles and the car you drive ?

We changed the hubs over to suit the 60 series Land Cruiser rims and think it cost $40 each side.

You've probably got the cost of rims to account for in that figureChip

I just bought a GXV rim which happens to fit the LX470 for $280. That's for an OEM Toyota alloy wheel. If you went steel it would be heaps cheaper. You can always get 100 series steel wheels from the tyre and wheel stores because people upgrade to mags and dump the steels. I bought steels with Grandtreks for a $100 each - ideal for the trailer. So its hard to see where the $1000 a trailer came from.

I've just done the same conversion to my trailer and a grand would be pretty close to the mark.Hubs are about $50 each,second hand rims were $60 each (you need three), Good off road tyres are $200 each,and as I found I needed a new axle because of the extra width and deep centres of the rims $140. That's Over a grand.
