Outer Limits 4x4 Board

Am about to buy a set of 2nd hand BFG m/t radials. 33x10.5x15 (new style)
The bloke selling them said bfg recommend tubes for them if you are going to deflate below 22psi.
The tyres are on rims and have the tubes in them, what I want to know, is that right?
because a local tyre dealer who sells BFG's reckons he's never heard of this and doesn't recommend running tubes.

Should I take the tubes out, what is the general consensus?

cheers

Just leave the tubes in and forget about it. No more blown beads is not a bad thing ...

Ran mine at 12 on a trip in Nov, no issues.
but as said, if they are in there leave em.

but I'd be interested to know WHY they are in there, do they have holes in the tires? Are the beads fucked and wont seal

I think that I've had mine as low as 16 and had no problems.

Tubes should be tyre chalked to prevent chaffing, especially on the ridges in tubeless tyres.
Tubes can get punctures from the dirt that forces in through your beads when deflated chaffing

just watch out for hiway driving, my mate hade tubes in ATs and he blew one of them on the freeway

Tubes are alright, but I'd prefer not to run them. Main reasons for not running them is:
a) Tyres run hotter = less mileage etc.
b) Get a puncture and it's a very fast leak that you can't keep pumping up until you get to a place to fix it.

The 33x10.50R15 is a tubeless Radial. As long as the previous owner hasn't had a puncture in the past you can run them tubeless. If he has you'll need to get a few plugs put into them.
One of the reasons BFG may suggest running tubes on these tyres is because they are tall and skinny. Tall skinny tyres at lower pressures have a tendancy of rolling a little more through the sidewalls which puts a bit more strain on the beads. The tube just keeps a bit more force behind the beads and stops air from leaking.

Thanks for those tips guys.

Ok the tyres have 11-12mm tread and are under 2 years old, he said he only used them off road.
He reckons they've never had a puncture and there's no signs of any damage, the tread blocks are even, not out of shape like they get with lots of bitumen driving.

Just to recap, he said he only ran tubes because BFG recommended doing so with this size if they are going to be deflated below 22psi which he often did off road.

I'm only getting them for this purpose also with a few kms of bitumen to get to off road destinations, keeping my road set for daily driving.

They are on factory Nissan GQ steel rims.
Anyone know the PCD of these?

I have some Cheviot alloys (15x7JJ) to put the tyres onto though, they're lighter and I like the look of 'em.

Ran mine at 12 on a trip in Nov, no issues.

Have tubes in them Bogged?

cheers

i have had no probs runing 10psi in my bfg muds 35x12.5. On road running 25psi and they are wearing even, done 30 thou on them and still have 70% on them. Stoked. Oh and tubless.

Well I've bought them, apparently the tubes are "heavy duty".

I thought a tube was just a tube

Factory GQ rims? Not split rims are they? That would explain a lot. I prefer not to run tubes in tyres, as low pressures can make tubes creep and rip out valve stems. Tyre chalking should prevent this, but not always.

Nup. White ones similar to sunnies but different, "teardrop kinda slots"

I was thinking about the tubes slipping at low pressure myself but I suppose if that happens it means the tyre is too?

typical BFG I think.. I get these things in at work all the time with a "puncture".. ends up being a shitty bead that doesn't seal properly

Nope no tubes Mr...
