Early to say anything on the rubber tubes longevity, but the finish to the product and the feel of the butyl rubber suggest that the quality of the tube is so much better than some previous 'cardboard texture' inner tubes I have wasted money on before. The angled pipe valve slipped through the split hub side hole with no problem and the tube inflated easily. Had a good feel to it on inflation. Packaging was good and states 'Made in Indonesia'. The home of rubber production seems to be a better source for this product rather than the usual source for most products of inferior quality.UPDATE: 9.4.21 Unfortunately despite little use discovered that rubber within inner circle has started to split after five months from purchase and inflation and is now not holding any air. I don't know what determines the longevity of rubber inner tubes, but this one does not have anything to recommend it now. Needless to say I will keep searching for something that is not a waste of money.

Appears to be good quality and glad i went for butyl option.Tube inserted and inflated. Not going to put it on the caravan until i am convinced it will stay up. Have tried hard plastic- dug in continuously and was a pain. Tried pnuematic- dont seem to stay inflated for long. Tried foam tyre which flattened and was useless.Now attempting a good quality inner tube as a last resort. So far, it is looking good. A much better quality tube than i have bought with the complete wheels that inevitably fail quickly. Time will tell!

The inner tube fits and now my kayak caddy works again! Pain in the backside to get the tyre off to replace the old, broken, inner tube (valve separated) and difficult to get the tyre back onto the rim afterwards (a bicycle tyre is far easier and quicker to repair) but that isn't a reason not to try a repair yourself! If you don't want the aggravation of doing it yourself, just pay more for a completely new tyre instead. This inner tube does exactly what I needed it to do - get my kayak caddy back into service.

This is exactly what i needed and came the same day as placing my order i needed this for work and there was no hold up!

Omg. I m so surprised, very strong and good quality. Still go on. Totally recommended this product for Electric scooters. As i bought it for my electric scooter and work perfectly.

fixed my truck wheel easily

Inexpensive way to upgrade existing trolley wheel maintenance.

A good product and easy to fit.
