Aldi bicycle inner tubes - faulty valves? 16 May 2019 at 11:32AM edited 30 November -1 at 1:00AM in Public Transport & Cycling 11 replies 1.6K views

Hello money-savers!

I recently thought I'd treat my bike to some new inner tubes so I got some of these (AV/Presta, 26"):

https://www.aldi.co.uk/26-27-5-inch-auto-valve-bicycle-tube/p/097682261898800

However when I replaced them I could hear the valve of the front tyre hissing and it completely deflated. Assuming a faulty valve I took it out and returned it for a replacement straight away but when I returned the back tyre had gone soft. To my amazement, even the replacement did the same.

Has anyone else had the same experience? Could I be doing something wrong. I only inflated them to 35psi using a compressor that I also bought in Aldi (plugs into the 12V supply in a car), could I have damaged the valves this way?

Do they have some sort of removable core for using sealant inside them? Only thing I can think of as I had that issue, albeit on a presta valve, as those ones do come loose and let air out. Otherwise maybe they were faulty, try pumping up with a hand pump. Not aware of any issues using a compressor as I've seen people doing bikes at petrol stations using that sort of valve

Is that for presta though? Looks quite small, the aldi ones are Schrader. The park one below does both

Its possible the puncture proofing liquid is stopping the valve from closing properly. Its happened to me.

Thanks for the replies. I've also spoken with a couple people at work who said this just shouldn't happen out of the box. I don't want to throw good money after bad getting a valve tool but I may try twisting the cores in a bit more with some long nose pliers, could be they haven't been tightened properly. Good shout about the slime too, some did come out of one of the valves when it was expelling air.

I would nt take much notice about them being "puncture proof "..Get better tyres.
Informing the users that they are puncture proof would imply they would not need to carry a pump or a spare tube and means of exchanging the tube.
I have` nt had a puncture on any of my 23 mm skinny road racing tyres with no tread for over three years..And that is with the tyre pressures at over 100 lb with rock hard tyres.
I reckon this slime in the tyres is just a gimmick..Adds weight to the revolving wheels requiring more energy to rotate them... Does nt work well in car tyres neither and gave the EU the chance to add another useless energy saving device just to lower the overall weight of the car getting rid of the spare wheel

Some valve caps have one on the end. Try checking your or friends cars.

I would never be inclined to go for a budget inner tube. Pay a couple of quid more and buy a better brand from one of the large online cycling retailers. Plenty of product reviews on their website to pick something a bit better.

Get a bike second hand to save a big chunk of cash, but always go for high quality tubes and tyres.

Its proabably the most likely component of a bicyle to need replacing, and even the good ones are not expensive.

You sure it isn't the rubber neck of the valve getting cut on the hole if the rim tape has moved or is not special?

I like Michelin tubes and Schwalbe puncture resistant tyres. All cost a lot more that these, but still MSE if you do many commute miles.
