Hi all! I would just like to know if anyone knows what thickness the tubes are on the AT. Today i tried to get heavy duty ones. After going almost to every shop someone were able to help me with 1.4mm thickness tubes. He told me it is still thicker than the oem tube.
Is this correct?

I had to change a tube before I bought my Alpina rims. It said ‘Heavy Duty’ on the box. I can only presume it was thicker than the oe tube.

Hi!

As far as I know.

Standard tubes: 1.2 - 1.4 millimeters - this is the type fitted and to be used further within the AT tires. Because, thicker tubes produce more heat (especially on road).

Heavy Duty tubes: 2.0 - 2.4 millimeters - not recommended to be used for the AT!

Ultra Heavy Duty tubes: ~ 4 millimeters - not recommended to be used for the AT!

The thickness of all types could vary from manufacturer to manufacturer of course.

Cheers, Gerhard

Why do you say HD tubes are not recommended to be used in the AT? Just because they "produce" more heat? Do you have data that helps to understand that statement?

Thinner tube vs HD tube vs UHD tube?

More heat means possible tire failure. Just check with the tube manufacturers. They clearly state that thick tubes are for off highway use only.

That's interesting about the HD and UHD tubes. I hadn't heard that before. I have a set of UHD tubes in my rear tire with 16,000 kilometres on them - no issues with heat or failure. Am I just lucky? I thought that the UHD tubes would hold up better to wear and tear. They are made by Michelin and Heidenau and are listed as a replacement tube for the bike online and were recommended by a motorcycle shop.

I did, however, have a puncture of the front OEM tube from a nail which was a bummer.

I have seen a failure of a UHD tube on sealed roads where it effectively split a seam, I would say that was heat related it was hot (tire and tube) and when we pulled the tube out of the tire it would tear along the seam very easily. No UHD tubes since then, in fact no tubes since then either Tubliss ore Outex but I still carry a light duty 19 tube. The guys at TuBliss put me onto the temperature problem with on highway and thick tubes. I measered the outside tire temp after I did a Tubliss conversion and they run much cooler than with a tube in there, averaging over 15 degC less (remember this is the outside) so I would think you could cook a heavy tube at sustained high speed.

Hi!

I've got the infos from 2 different sources (my tire supplier and my local Honda dealer too) and, no I don't have statistics and/or data for.

Further, as written it's "not recommended" but, not forbidden.

I run a HD tube at the front by my on AT at the moment (when changing the tire I only have this type handy).

Never the less it sounds logical to me: Heavier bike => more tire movement = stiffer tube (HD or UHD) isn't as flexible as a normal one => more movement between tire and tube => more heat produced. Once again, especially on highway use it sounds logical to me. More and/or only off road use I guess it could make sense to go for HD/UHD (I think it's somehow similar as when using a Mousse on Enduro bikes => road speed = heat which kills the Mousse quickly ).

Also do not forget the HD/UHD tubes have more weight => more rotating mass.

Cheers, gerhard
