Inner tube - when to replace?

[crankedup]

Six years ago I fitted new tyres and inner tubes to my classic caravan. I noticed that one of the tyres is just starting to show some age related wear, as in slight side wall cracking. I intend to replace both tyres but am unsure as to whether I need to replace the inner tubes at the same time, I am thinking that they are not subjected to the same weather related problems as the tyres. The tubes are quite expensive at around £80 each so obviously do not want to replace unless it is safety related.

When I bought new tyres from Blockley, Julian advised me to change the tubes because they could suffer from ageing just like a tyre. I honestly can't remember how old the tubes were, but I did change them and they have served well - the old ones that is - in the pool! On reflection, I guess the old tubes were about 20 years old. Perhaps MWS or Blockley might be the people to talk to?

Wow, £80 each! Someone's having a laugh surely? Take a look at Motor Wheel Services (MWS) they have inner tubes in all diameters and for example 14" ones are £7.50

Seems very odd

Opps, my mistake it works out £33 each + £10 fitting each. so its about £80 for the pair. My tube size is 475 - 21.

Crikey 21" wheels on a caravan they're big. Anyway fitting is really a red herring because you're getting the tyres changed at the same time. So, £66 ... I think I'd swap the tubes as well.

p.s. looks like a fun combination - bit of a contrast with the Griff

Yes your right, £66 it has to be sensible.
The Griff went some years back now, must update my profile! Had a number of vintage cars since but the Vauxhall and Eccles caravan fit my bill, brilliant fun. No fear of getting caught speeding either

I hire both out, car for occasions and caravan for all possibilities!
