Banding rims.

No problem. They may advise against it on the basis of the retention bead on the rim should be on the outside - I didn't have to worry about such things, as I said, mine are for (very low speed) off road use and I'm also running tubes.

But depending how they do the job, maybe they could add a retaining bead.

I've sent an email asking if its possible to flip centres and band the out 50mm, centre flip would yield ET00 banding would give the necessary width of wheel rim, see if he replies now or wait until later.

Broad speaking open conversations in the country that appears to have invented not just metric but also several versions of imperial weights and measures should be enjoyed, not ridiculed.

9" rim to suit an 11½” tyre,

They don't have to be an exact match but the difference quoted above looks a bit excessive to me. Usually I'd aim to have the tread width similar to the rim width, preferably with the tread narrower than the rim rather than wider. A wider tread on a narrow rim tends to pick up the inside edge under side loads which can give some strange handling characteristics near the limit.

For the road tyres I'm familiar width, the tyre nominal width is quoted at the widest point of the sidewall when installed on the recommended rim size and in the sizes I use this works out to about an inch wider than the tread as a rough guide. So I'm used to seeing tyres nominally up to about an inch wider than the rim. I suspect an extra inch on the tyre width is going to distort the sidewalls quite noticeably and in the wrong direction.

This is for an off road vehicle that will have an 8 1/2 inch sidewall depth, I am fully expecting sidewall distortion over rocks when I'm running 12psi or even sand running 20psi

The tyres in question.





Perhaps we tread in different circles, I'm concerned that I will have my rims too exposed.

Off road tyres can be fitted to narrower wheels than a similar width road tyre.
The manufactures website should give a range of wheel widths the tyre will work on.

[InitialDave]

Yes, I think you can use a narrower wheel if you wish.

BF Goodrich, for example, specify 7.5" to 9" for a 285/75R16, and their reference measurements are when on an 8" rim.

I currently run 235/85 r16 on 16X7 rims and they're perfect with good sidewall protection for the rims.

I had considered just buying wheels but they're all bland and if you go for custom rims you can triple the cost of getting these banded and flipped.

I see what you did there!

Yes, we do. I'm dealing with road cars on tarmac where contact patch size/shape matters. I suspect in your case the contact patch is whatever shape the tyre decides to stamp into the ground.

Unlike EVERY single tyre sold in the UK today which will be something like 17 (") x 225 (mm) x 45 (%)

As a sobering thought might I suggest that you look closely at the Disco shown in the picture in this article: www.bbc.co.uk/news/uk-england-lincolnshire-4333163...

That is awful, her poor mother must have been through hell considering she had already battled leukaemia for 3 years.

Terrible for them but i found it even more distasteful to see the anti 4X4 brigade lead the charge, their motto being "never let a good tragedy go to waste".

It is still unclear what caused the accident and speculation is unwarranted considering the thousands of accidents annually on Britain roads.

I agree, it doesn't help anyone. However I have to wonder why the investigation is taking so long, the cause of the failure shouldn't be hard to determine.

Standard procedure in a fatality I'm afraid

The rims are off and in the hands of TNT for delivery with the machinist, all being well they're going to be there by Thursday and back to me by end of next week being 2" wider and looking a lot nicer.
