run-flat? NOT!

Ok so the Tyron fills the well in the rim, stopping the bead falling into it on one side and coming off the rim in the other.
It's quite clear that the Tyron doesn't stop the bead from coming out of its seat which is the greatest concern for low pressure driving. It just stops the tyre from coming off the rim and hitting other traffic.
If you go far enough on a flat tyre to unseat a bead (puncture at motorway speeds for ex.), your tyre is pretty much dead anyway. The Tyron seems only to ensure that you don't have to go looking for your tyre on the side of the road.
Real run-flats have a loadbearing band higher than the rim edges, consequently, they're a bugger to install unless you've got a demountable rim like the Humvee.

IMHO the tyron doesn't have any advantages for low pressure driving.
happy trails

So the tyron band has no advantages in low pressure driving - but does it have any disadvantages for low pressure driving?. Should I consider binning the things or will they just sit there undeterred by low pressure and deforming tyres scraping over the sand.

Smile tyres ? which way now ?

Ok I have a dil I am running an iveco 35-10 4x4 (ex RAF).
Currently equiped with the Michelin XZY 7.50 R16 tyres on 'split rim' style rims.
I have 2 tyres which need replacing now.
Planning trip to Mongolia (via Turkey) next year (yes was originally going this year but alas plans forced to change ! !)

I have following questions :

The XZY has apparently been replaced by the XPC (which i assume is as good) but is this preferable to the BF G 235/85 ? (i get conflicting info but people seem to be saying BFG better) ????

Are 'split rims' a pain in arse to change in the field ? should i look to replace the rims with more conventional ? (and if so then any ideas where from ? ) ????

Is it acceptable to replace just the 2 rear tyres? i.e. put couple of BFG's on rear and keep XZY's on front until they need replacing (approx 5 or 6000kms) (I am being told to replace all 4 now - but expensive !) ????

Also, lastly, I need advice on reasonable compressor to buy (and from ?) bearing in mind i will invariablly be deflating and reflating a great deal !!!! ????

Many thanks guys.

I have a set of 5 XZYs and 110 rims sitting in my garage that I'd like shot of. 1 at 10mm tread remaining, 2 at 9mm and 2 at 4mm. I'm in Bristol so let me know if you're interested.

IME the "Truckair" is very slow and the T-max compressor we took with us bust its bigend (for want of a better way of putting it ) after pretty minimal use and was unrepairable. Thankfully it happened where we could borrow another compressor

I had two truckairs in africa, both failed within a few days, always carry a manual pump just in case, we had 1 per vehicle (2) and managed to break both of those as well!!
a word on the XZ, according to the guy at vass the blocks can pull away from the tyre base, he reckons the XCL (XL) is better, although that is a more aggressive mud tyre. they supplied me with some michelin XS copy sand tyres by continental which were excellent and cost only £40 each, and that may include the rims if you need them.

How much are you looking for, for the wheels?

Question Michelin XZY

My Defender 90 has been running on Michelin LTX 245/75R16 tires, on and offroad with no problems for the last 6 or 7 years, +/- 60000kms.
Off road driving is mainly desert stuff, sand and rocks. The car is well loaded though.
I need to change my tires, and was advised to look for the Michelin XZY, which are very difficult to find, specially in Egypt! Having had a good experience with the mounted tires, I could go for the same, although I would like to upgrade to see if there is a difference.
Advice anybody?

A bit more info on those wheels/tyres from Vass - I had a set about four years ago, think I paid £25 quid per wheel/tyre then!

I was told they were taken from the Northern Ireland armoured land rovers, before they were adapted with G90's, painted sand and shipped out to Iraq.
They had the run flat bands to stop the tyres falling off the rim if they got shot out so they could keep going - and presumably to stop the tyre disappearing down the road if someone turned too tightly with all that armour on.
They are long wheel base rims - again used because of the weight of the trucks.
Great tyres, last f o o o o r e v v v v e r !!! on those rims though they are bloody heavy.
Tyres aren't very good in mud, don't think I drove them in sand but I've heard very good reports about them, particularly how resistant to punctures they are.

Always ran mine 30 front/40 back and adapted a bit if I was carrying weight.

EDIT - Bloody hell - just noticed how old this thread is - I was thinking it was a bit odd that Vass were still flogging those tyres!

VASS still selling

I spoke with VASS about a month ago and they are still selling. The price was the same, but delivery had gone up 20 quid from when this thread started. Don't buy the last 6 though, they're mine .
