Before you read any further all i,m asking for is an official specification of an inner tube.. STD.. HD.. EHD... Thats ALL!

Hi All,

Just purchased a Heavy Duty inner tube and on delivery noticed it wasn't particularly thick, so out came the calipers and it measures 2.6mm meaning a single wall would be 1.3mm?

Now i,m in talks with the dealer (he says all his tubes measure 3.274mm.. which to me means about 1.6mm skin wall = Standard tube) Could really could do with some official statistics with regards what the standard is for inner tubes.

I know a heavy duty inner tube should 2 - 3mm, but i don't think my word is good enough, so if you have any links to official body's it would be appreciated.

also in the process of contacting iso.org to see if there are any specs.

Regards,

Rod

No worries.. just need to prove to the dealer that 1.6mm thick tube is not heavy duty and he isnt accepting my word for it! :x

What brand is it? go to manufacturers web site and look up the spec. Some do heavy duty and extra heavy duty.
Example
Michelin Ultra Heavy-Duty Inner Tube
Featuring a 4mm wall thickness,
The Vee Rubber Ultra-Heavy Duty tubes are manufactured using 3mm thick rubber

I bought something similar in the past and I still see them for sale on ebay as heavy duty. See the link below. It all ended well as they are perfect to carry as spares as they are far lighter and take up less space than v rubber, michelin etc.

If the thickness of an inner tube is such a concern to you I have to question your motive or objective.

If you want to remove the chance of a puncture get a mousse. If you want something heavier than a mousse and heavier than a standard tube which will still puncture get a heavy duty inner tube.

Sod the legal arguments......do you always keep to the speed limit in your car?

Greetings,

Guess the problem is that there is no legal definition or specification, it is simply a description.

You can only check the individual manufacturer's specification and compare, if it fits the dimensions etc then that is the end of the line and you write it off to experience. Maybe the seller would swop the tube for one from a different manufacturer, adjusting the cost accordingly.

Personally I currently use Michelin Reinforced 2.6 tubes, I know exactly what I am buying. I have used Continental too which gave good service too. Michelin do make a HD 4mm version which have given me excellent service in the past but they are very heavy. I always generously dust the inside of the tyre with talcum powder as it helps to lube and cool the surfaces, you smell nice too according to Joel :shock:

I attach a photo of an offending article which is as it was removed from my rear tyre whilst out on a ride. The tube was so wrapped around the nail that we had to cut it off before we could remove the nail :!: No tube would resist that attack :twisted:

Other riders choose other marques, but I think that I will stick with Michelin even though they generally tend to cost a little bit more upfront.

You could always sell it to make tank straps, (see other Post) :lol:

TTFN

Hugh.
