How can I tell if the tyres on my Morris Minor are tubed or tubeless?
Is there any writing on the sidewall to tell me?

it should say
but if you look where the valve comes out of the rim if it comes straight out its tubered
if its got a big lump of rubber as it comes out then its tubered less
|
Let the tyre down and see if there is any play in the valve.
You can't rely on what's written on the side of the tyre.
With cars of this age, a routine answer to a tubeless tyre not sealing, or to a puncture, was to "pop a tube in".
I seem to recall some tyres were either/or and were stamped 'tubed/tubeless'.

bell boy is spot on
As an added guide compare the moggy valves with your MB valves.
If they look the same then they are both "tubered less ".
|
The OP is asking about tyre type, not whether or not he has tubes fitted.
Tubeless tyres are, in my experience, marked as so.
Tube tyres are not marked 'tubeless'.
|
I am interested to know whether or not my tyres are tubeless and also if they have had tubes fitted!
This is because I have a slow puncture, which for a car that doesn't move all that frequently, could be a nuisance. I intend putting jollop into the tyre, which I understand one shouldn't do if tubes have been fitted.
Perhaps I should wander down to the staff quarters and ask Jenkins what it says on the tyres.

Or maybe even take it to a tyre place to get it fixed?

IME you don't get 'slow' punctures with tubed tyres. If you get a puncture then they go down fairly quick, usually within a few hours.
Tubeless tyres on the other hand tend to deflate very slowly when punctured unless the item causing the puncture is removed. What many people call a 'slow' puncture is in fact a true puncture with the offending item plugging the hole.
Other causes of slow deflation could be a leaky valve or corrosion on the wheel rim not allowing a tubeless tyre to seal perfectly - quite likely with an older vehicle.
It might be worth sending Jenkins and wheel to your local tyre place - give him a stick and could have fun rolling it there.
|
Another cause of leakage could be that someone has put a tubeless tyre (without an inner tube in) on a rim designed for a tubed tyre. the rim won't seal properly and neither will the valve hole with a tubeless valve.

Yes, I might just do that, I think he must be due an afternoon off next month.

That wasn't immediately clear to me. You mean he is worried that although the tyres are of the kind that need tubes, these have in fact been omitted?
IME tyres intended to run without tubes say "tubeless". Tyres only intended for tubes don't necessarily say so. But most full profile tyres can be fitted with tubes, eg if the rim won't seal properly. Some kinds of wheel have to have tubes regardless, eg wire wheels or off-roaders.
You can certainly get slow leaks with tubed tyres, as with tubeless.

Perhaps my original question was not as precisely phrased as it could have been.
Because I have a slow puncture, I am thinking of putting Tyreweld - or similar - into my tyre. I understand that it is not recommended to do that with tubed tyres.
The car is not kept at drbe Towers, so it isn't that easy to take a look.
I do hope that clears up any confusion. Of course, as has been suggested I could have the car taken to a tyre place and get them to sort it out. Any recommendations in the KT10 postcode area?

why would anyone who isnt stuck on the A1 at midnight on a wet sunday evening not take wheel and tyre to a tyre place to have the tyre casing inspected just in case a nice juicy nail isnt slowly eating through the sidewall everytime james gives it an old tickle up the bypass ?
|
Worth checking the valve is tight and there are not any little pieces of grit lodged in the valve or under the dust cap.
Also try the 'gob test' on the valve.
You can still get metal dust caps that double as valve keys.
