I had the same wobble when I bought a new set of steelies with BFG KO2s for my 15 DMAX. I took it back to Bob Jane twice but not really any better. I investigated a little but most of the lingo in this thread is beyond my knowledge. Basically what I figured out was that Bob Jane didn't have the right stuff to do the job. Ended up taking it to a Dunlop tyre place I drive past twice everyday and they balanced them correctly, never had the problem anymore.

The balancing thing was something id heard about and i have had a few issues and im about to get them balanced and a wheel alignment done again but i have a feeling this might be down to the bob jane shop who fit them for me. They did some less than average things when fitting my first set that led to me making them replace the first set of wheels and tires with another brand new set. They used a set of cheapo black wheel nuts that chewed the hell out of the face on the wheel, its something that blind freddy would have noticed as metal shavings were poking out from between the nut and the wheel. I took a nut off at home and saw what it had done to the wheel and drove it straight back and made them replace them. Didnt give me a lot of confidence in their work after that.

They have been ok for the last few months but a vibration has developed at about 75-90 ks. I wont be taking it back them though.

I've not seen any major burring at the mounting surface to my wheels, but they are fairly old and holes aren't perfect now. The nuts are fairly good, but as Tom pointed out, I've never checked if these two surfaces are meant for each other.

I was actually talking to a Bob Jane about Dynamic wheels! They're the catalyst for this post!! I might look at other brands if you are having these problems, maybe Kings.

I was wondering if anyone knows whether 17" wheels off a Prado may suit?
If you've got good tyres on the 18's, I'd use them. You've already got 160mm if sidewall on these, heaps enough. Or get a set of good ATs on these rims of a similar profile. Although, it is cheaper for smaller tyres. From previous experience, 16" with 75 profile puts you into light truck territory. Not something I'd recommend as the rubber is harder and not as grippy. I had a set of Toyo Open Country H/T's that were up to 125,000Km and still had about 10mm of tread, but had gone really hard (took 5 years to get to this) and were hopeless in the wet.

Your Prado wheels should fit, same PCD.

I actually read something on a ranger forum ages ago about having to get them balanced with a certain type of machine. Could explain why yours were sorted by someone else. As soon as i get a chance ill do the same.

Failing that, i have a bloke who is a gun mechanic and who is actually intrested in solving problems and not just plugging a computer in and seeing what it spits out. Ill give it to him till its sorted.

Steelies that locate on the studs should be balanced with a finger style jig that centers the rim around the stud holes, not the centrebore of the rim.

There are also radial force balancing machines that will balance the wheel and tyre taking into account differences in the force needed to deform the sidewall/tread around the circumference of the tyre.

Yeah there are on car balancing machines but they are pretty old tech, I only used one once when I was learning my trade at TAFE in the early 00's. Not sure if there are modernised versions around.

EDIT: saw you mentioned without machines. Balance beads inside the tyre are said to work well.

Here is a good vid to explain how they work

while we're on the subject of misfit rims & tyres, how about:
how bad is 31x10.5r 15 tyres (remember them) on 6.5" wide rims when min recommended width is 7".

at least these rims are correct to the hub!

It'd be good in sand but terrible on tar. Also, it's definitely illegal to run a rim less than the width on the tyre placard.

That's a bit out there.

When we were involved with Nascar the mandated rim width was 9.5'' and the tread width of the tyre was about 12''. Looked ok with tall cross plys, not so much when we went to radials.

Steel wheels on the cars, not hub centric.
Twin tyres 45 psi in the outer 65 psi in the inner on the right front. 3500 lb car + driver, 52 % nose weight massive aero on cars like the old tbirds, 24 degree banking adding even more load, 5 5/8 studs on a 5'' pcd. 100 % reliable, even for wacking the concrete wall.

But that's got nothing to do with street legalities.
