Cracked Wheel Rim

[Mike&Loz]

Morning fellow campers. Here is a couple of pics of a cracked Dynamic rim I just replaced.

I heard a clicking noise coming from the front of the car when I was turning and couldn't for the life of me work out what it was. Checked everything thinking it might be a CV on its way out but nothing wrong there.

Still perplexed I did my routine tyre rotation and the noise from the front disappeared. A couple days later I heard the noise again and couldn't quite get a location. Then my grandson said it sounded like it ws coming from the back. I had a look and again could spot anything. I probably should have washed the wheels first eh?

Driving the other day and a sudden shudder at about 80kph gave me cause for concern. I only had about 10k to go before I was home and did a quick walk around. Bugger me if didn't spot this straight away. Changed out for the spare and now I am down to 5 rims and 6 tyres.

Just looking at that photo, were the wheel nuts ever left loose for a period of time?

The stud holes look to be elongated in the photo

May have something to do with the failure

[Mike&Loz]

Wheel nuts checked regularly and were never loose as far as I know. They were definitely tight when I removed them. May be due to the cracking and the resulting vibration.

I think the holes only look elongated because the metal is raised at the centres and drops away below and above the nut contact areas with a resultant shorter contact face.

Wow! That's scary.
Looks like another reason to steer clear of the Dynamic rims. In Vic. at least, they render the car unroadworthy due to rim offset. An accident deemed due to rim failure could void your insurance. Scary!!

Have you sent the photo's to the Dynamic distributor for comment. It'd be interesting to hear.

[TerryO]

Glad I bought second hand set of 17" BB6's now. Baz was recently considering buying a new set of these rims, he might change his mind now.

Hey Mike if you still have the standard 18" rims that your D3 came with then I'd consider putting them back on especially given that your going to be towing a van which would put even greater stress on the Dynamic rims.

You won't see the OEM rims cracking I bet.

cheers,
Terry

Hadn't considered that option Owl but it might be worth it. Without knowing the full history of the rim's usage though it might not come to anything. Still it may help them with future R&D.

What is the weight rating of those dynamic rims?

Still got them Terry and I've been giving that option real serious consideration. The only downside to them was the cost of tyres in that diameter. Although importing 6 tyres from the US is only $1800 compared to a smadge under $3600 here, I can still justify it. Given that I am now down to 5 rims of each now it is probably the better option. 5 tyres on rims and one on the roof rack along with a spare tyre for the van.

What are BB6s? I've not heard of them before.

Where is the best place to import them from,i have been looking at tirerack,but with freight there isn't much saving.

[stewmair]

My Dynamic 17's have circular holes. This was a change which I thought might be due to copyright infringement but may have been due to strength. They look stronger. My wheels are of legal offset. Perhaps that has also been changed.
I have had no problems.

[jonesy63]

What is the weight rating of those dynamic rims?

Garry - they're rated at 1400kg.

[101RRS]

Garry - they're rated at 1400kg.

Thanks - plenty of spare capacity.

I've just had a brand new dynamic rim replaced under warranty as it leaked air from a dodgy weld.
My tyre fitter said its not the first time he's seen that.
I don't think I'll buy dynamics again as I don't really trust the ones on the vehicle now.

[d3viate]

I too have just sent in photos to Dynamic of rim cracked at weld for a claim which I am waiting for reply. Weld has undercut and for some reason quality control let them through. Pulled up at Three Ways with (new) tyre going down thinking I had picked up a dreaded tec screw at servo.

[Mike&Loz]

Thanks Terry

I've pretty much decided to use the 18" OEM alloys I have and save some money. I'll just order the tyres from the US.

I've sent an email to Dynamic and they have responded indicating that the rim may have been stressed by overloading. As they are rated 1450kg it is unlikely that is the case however I can't vouch for the previous owner's usage.

[TerryO]

Pretty hard to overload a rim on a D3 that is rated at 1450kg, that means a weight in excess of 2900kg on the rear axle. Or a very very heavy winch and bar on the front ...;)

The standard 18's your D3 came with look far better then Dynamic rims anyway and it will handle better with 18's rather then 17's even if the tyres cost a few bucks more.

Have you priced recently Yokohama's from the tire shed or what ever it is called, last time I looked some months ago they were very cheap compared to here and they are according to most people a pretty good tyre.

cheers,
Terry

This is the replay I got back from Tirerack:


Mike,

5 BF Goodrich AT TA KO will run you $1834.83. 5 BF Goodrich Rugged Terrains will run you $1429.83.

Let me know when you're ready to place the order.

Thanks.

That was for 265/65R18 size delivered to my home. The price here in Perth was $580 each so my maths was a bit off and should have read just under $3k. I'd have to get them to split the load so I came in under the $1000 threshold for GST.

I would shop around a bit more as these can be got for a bit under $500.

That is a lot of money for an old fashioned tyre, yes it is tough but it's performance has been overtaken by newer designs.
The older MT and now the MT KM2 are better in the sand than the AT. The square shoulder on the AT digs in even when deflated.
Wet road performance is also questionable.

My 2c worth.

Agree with you as far as overloading goes. It's take a fair bit of stuff to reach the rated load. As for the tyres, I am pretty biased toward BFG having had excellent service from two sets on my Pajero on and off road as well as towing a 2.2t van. Unless someone can recommend another tyre that is as good or better I'll probably stick with them.

I think tyre choice a matter of personal preference and first hand experience. If you have a bad run with a particular brand it puts you right off them no matter the reason.

I can't comment on the Yokohamas as the only set I had were the OEM Geolanders (HT) fitted to the Pajero when we bought it and like all OEM tyres only lasted 45,000km.

And as John Laws used to say "When you're on a good thing. Stick to it."

Mike

[TerryO]

I considered getting the the 265x65x18's as well Mike but that would make the D3 unroadworthy if pulled over by the RTA because they are to far oversize stopped me. That and the fact if something went wrong with that size tyre on that my insurance company might walk away from any claim.

Just a thought to consider.

265x60x18's are fine though.

cheers,
Terry

[Owl]

..... My wheels are of legal offset. Perhaps that has also been changed.


Are you sure? I've been told in the past by people who should know that it is not possible to make a steel rim with +41mm offset and reasonable load capacity. If someone has found a way it'd be good to know.

What is the offset of your rims? Dynamic steel rims used to be +30mm.

[Owl]

....... I'd have to get them to split the load so I came in under the $1000 threshold for GST.

Mike

That doesn't work - Customs monitor delivery's to your address, and if 2 come from the same source in the same year, they combine them for tax purposes.

You may have to have some sent to your brother/sister/aunt .......:wasntme:

In the progressive, forward thinking state of WA, 265/65R18's are legal on a D4 - only 40mm oversize and we're allowed 50 :D

Cheers,

Gordon

[scarry]

i also have had a fantastic run on BFG A/T's on the D2.
I am looking around for something for the D4,will probably go 17's.Has anyone got the Rugged terrains,they are not to be confused with the old rugged trails.

They are a little more road based than the KO A/T's,& probably suit a modern car such as a D4 better than the KO's.

But are they as robust,are the side walls as strong?The load rating is identicle in 245/70/17 size.

They ar both similarly priced here at around $350 each.

My other option is stay with the 18's,but there are no LT's in this size unless i go to much larger tyres such as 265/65/18,which is not what i wanna do.

Thanks Gordon. Equivalent size is the 265/70R17 and my speedo agrees with my GPS at all speeds. That's why I was looking for tyres in the 265/65R18 range to go the OEM rims. Because we will be vanning for quite some time they need to be at least LT construction with an off road capability. Muddies, in my opinion only, are too aggressive for towing large vans and, as well as wearing very quickly, add to fuel consumption.

[Dingmark Jim]

As far as splitting the shipments to keep below the $1000 limit, I have a very cooperative neighbour. In a case like this, I pay for 1/2 of a shipment on my credit card with my home address. He pays for the other 1/2 on his credit card to his address and we sort out the balance before credit card payments are due. He fixes up old cars, so I often return the favour to him. Works very well and all above board.

Thank for this info i sell these rims at work have seen the stud holes like that before and sent them back but good to see the crack i will keep a eye out on the rims to see if any faults..

[Mike&Loz]

Chris Hummer at Dynamic is being very helpful. I have explained that I'm not looking for a replacement or any form of compensation. He has agreed that inspecting the rim may help to avoid future incidents and is arranging for it to be inspected at Perth 4X4 in Balcatta.

No he is good like that wiil help as much as he can..

Victoria has now also adopted the new COP so 50mm bigger tyres are now legal.

That's great news. When did that happen?

My off road tyres might now be legal!
