Is it just me or have any other forumites exprienced a seemingly endless number of flat tyres when running split rim tubed tyres? I have had a LC 105 now for 2 years and have had 6 flats. More than I have had since I have been driving. Crikey thats nearly 40 years!!!

Only one was caused by somethging obvious - a nail. The rest just got tiny pin holes in the tube and leaked slowly. I have always been careful and cleaned out the tyre carcass of sand, grit etc when replacing/repairing the tube.

It seems to me that the tubes may be at fault.

Anyone had any experience of this?

None so far on the Luxie for just over two years, touch wood. I did pull a rusty nail out of the Road Grippers at one stage but it had'nt penetrated the tube - whew!!!

What brand are the tubes? Anything korean is very suss especially Mr Tubes brand, they get pinholes in them.
I found it was best to use the original dunlops or buy michelin tubes.
When you have a Dunlop and a korean tube on hand compare the weight of them both, the Korean one weighs half what the good one does.

Yeh I have.

Makes sure the stickers *inside* of the tyre case are removed before fitting! I was really peeved off after I bought new coopers from a cooper dealer and told him to remove the stickers only to find that he didn't. Trouble was I was in the Simpson when the stickers finally reacted with the tubes and caused the punctures. They somehow cause tiny pinholes in the tubes - even the best brands of tubes.

All tyre fitters know that the stickers *must* be removed if fitting tubes but with some stickers in can be a real pain of a job - hence they don't bother.

Thanks for your question darcla. No, the tyres are Dunlop Roadgrippers and came standard with tubes.

In the archives you'll find theres a whole bunch of people who swear by splits and the rest who swear at them. Poor quality tubes are pretty common these days. I reckon the rubber companies have forgotten how to make them, or in the case of Korean tubes, may have never learned.

I gave up on splits 10 years ago, after having them on '55, '47 and '60 series LandCruisers - too many flats and not from punctures. Tubeless suit me fine now - Punctures are now rare, and when we go away, all punctures are simply plugged.

I ran standard 7.50x16 for 30 years. Few punctures a year on average. Then changed to 235's Kellys and no punctures. Bought a new set and new tubes...2 blowouts within 100K with the same tyre that had been fixed by the tyre "experts" in Alice Springs. Both blowouts were not punctures so I suspected the tubes.
So I've changed to tubeless steel rims now. I *hope* that I won't have as many problems now. But just in case Murphy is still with me, I've added a rear tyre carrier so that I carry two complete spares, tubes, tyre changing and fixing gear and a compressor etc.
My experience was that most problems in the bush were either tyre or electrical related.

Use splits only...with many types of tyres / brands ...but all tyres are fitted with Michelin Tubes....nothing else Korean , No Dunlops...and nothing but Michelin....and no dramas...none..but rocks still punch holes through all tyre types when the opportunity arises !!!

I run splits and tubes on a 105 Series, and haven't had a flat ever (well, in 14 months or so of owning it).

I have, in the past 10 years, probably only had 3 flats, all on tubeless tyres. I used to do some crazy stuff too (do you know where a suzuki sierras waterline is? I do... Did you know it is possible to drive from the top of the hill above emu plains, all the way down to the hawkesbury river in a straight line? It is....)

Currently we run the 7.5 * 16, and while I love the fuel economy that comes with them, I'll be changing to 235/85's (if I can) when they run down a bit more. Reason is my last 4by was a Defender, and it went everywhere on those tyres.

I am a fan of narrower, taller tyres, you might have guessed. My first fourby was an ex-army landrover, with those solid, rounded tyres that had grooves 4 inches apart, and 2 inches deep. If I could get tyres reliably that were, say, 20cm wide, but with an aspect of 200% on 16 inch rims, I would be a happy camper. Imagine those puppies aired down - they would have almost a meter long footprint!!! And yes, I know this is not possible, so don't jump all over

Still undecided wether to run tubes or tubeless - if there are no more flats, I'll stick with the tubes. They are serving me well so far!

Looks like the general consensus is quality tubes (ie Michelin). i think mine are korean or such!

I too like splits and use sensible pressures. Interesting about the stickers inside case. Would not have thought of that . My tyres are the standard 7.50 x 16 8 ply Dunlop Roadgrippers. Will probably upgrade them soon too when they wear out

thanks again...............

Some years ago I had a spare Korean tube in its plastic wrapper in my garage & over time it literally disintegrated into a useless pack of gum with almost no tensile strength. Enough said!

Hi Johnotoo,
My experience on 5 Landcruiser's over dare I say it, nearly 30 years mirrors what the other guys are saying about splits.
Good quality tubes and keep the internals clean. No stickers, dirt, rust flakes, sand etc.
Anything caught between the tyre and the tube will rub through the thinnest and lightest component, the tube.
Crook tubes just rot away before your eye's.
Also good quality and clean rust bands.
