swamper over sized wheel carrier

[Domus]

I've recently been through a similar process, by fitting 235/55R18 tyres on Amarok rims on my new 4-motion T6.1.

While numerous people mentioned that this size tyre fit in the standard wheel carrier with the carrier set on lowest setting, we couldnt do it, even with the tyre deflated.

Without resorting to expensive Siekel carriers, I leant on a family friend who is a custom coachbuilder/panelbeater, and I'm pleased with the results.

We inserted shaped steel 25mm band at the front of the carrier, as per others on this thread.

Then, with some 25mm cut pipe as spacers at the front of the carrier, we were able to use the original bolts - longer bolts not required. The fitment of the bolts at the front does need some leverage from long screwdriver to bring the front of the carrier inline with the bolt holes.

We were able to use the factory bolt, noting that i'll replace the captive bolt (shorter thread) with a longer full thread version so both bolts have full thread engagement.

As a result, we didnt have to trim any of the plastic liner (those Siekel instructions to cut off the chassis bracket and then trim the plastic are shocking to me for such an expensive solution) and the tyre fits neatly in the slot - earlier it was a long way from fitting.

Very happy with the result. The carrier sits maybe 25mm below the rear diff housing, and the rear approach angle not quite what it was, but its a good outcome for minimal cash.

Do you have any more pics showing the process? I am trying to fit my 235/55/18 Grabber AT3 and struggling. Thank you!

I run exactly the same tyres as you bud but are working ATM. I'll post you a simple sketch later of how I cut and welded mine. Half hour job to do if you have or know a welder.

That’s brilliant, thank you very much! I can weld

Bit rough but you get the idea.

So you only add material at the back? Have just ordered some Caravelle bolts (longer)

 

[Dannyb6467]

Yep only at the back to give it depth. Diameter of the carrier with 235 55 18 is fine. There's enough length on the standard bolt

Sorry for the late reply. I’m on vacation.
The sketch below is a good representation for what my mate (a panel beater) did to the support frame.
I did end up buying the longer genuine VW bolts and spacers as the original bolts were close to impossible to insert with the wider tyres.
BTW I’m finding the 235/55R18 to be a bit too large overall with the speedo now under reading. I wish I could find a 235/50R18 with the right load rating.

We modify the standard carrier to fit a big wheel

Hi. It's an old thread but do still modify carrier. I'm currently running 235/55/18 ATs what size could I put standard to match and and what can you guys do.
Thanks

 

[BognorMotors]

Yes we do. Give us a call in the week and we can work through some options

Anyone tried this with a 245/65/R17?

Recently caught out with a valve fail. 4mo so the spare is useless. Fine at home but problem on the road...

Yep, got a 245/65/R17 BFG in my wheel well with a modified carrier but I ain't got a 4mo and it's a T6

 

[Randolph]

Biggest tyre size I can fit in the standard carrier is 225/65 r17.
Check it against your size on a tyre comparison site.

[Barberrossa05]

I'm choosing this answer... modded as above with a bit of welding?

What do i need to do to the carrier etc to get a 245/65/17 underneath ? We used to run 235/65/17 and with a bit of lube and brute force we could get that in, but never ever tried the larger wheel. Can someone post a link or details of whats needed ? Thank you !
