Inner tubes

[Devon lad]

Our scraper tractor, seems to get slow punctures quite a bit and it’s getting annoying now. We do have a tight yard and the tyres get caught very lightly some times, there is the odd surface cut. The cut is no deeper than 5mm on the side walls. The rims are a couple years old and are like new, the tubes and bkt tyres are about 5 years old. Whenever I do a puncture repair I can never find the cause, I just patch it, it often just looks thin on the bit that’s got the small hole and it’s fine for 6 months. Are newish tubes really poor quality these days? I know the older ones are a lot thicker. Are there good brands of tubes, or are these outer cuts causing the problems, unfortunately the tractor is driven by multiple people so pinning down if someone’s hit an rsj is not easy. Thanks in advance.

If you think it could be the cut in the sidewalk causing the problem, stick a big tyre patch behind it.

Like this, it’s worn on side wall on the inside of the tyre, I’m going to try to convert to tubeless

Tubeless are far more reliable than tube type. We had tubes in our scraper, slow punctures happened a lot. If you have a tight yard debris can be forced from the rims into the tyre where it will rub between tyre and tube, as shown in one of your photos.

Get yourself a Kleber tube, they are a lot dearer than the Chinese ones places put in but are way superior. Also ask the tyre fitter to use your old tube as a kind of condom for all the world, he'll have to cut it all the way around then put the new tube inside it, it will help the new tube from being pinched.

Looks like you could do with the sidewall from another tyre on the outside,stock cars used to do this to protect the tyre.
