Tube Types

[5azzmonkey]

I want to buy a couple of spare tubes but I don't understand what the different types are.

What's the difference between Type A, Type B, Type C and Type D?

What does my GS1100EZ require?

Needing some educating

Thanks,
Dave

Sorry, I have never heard of any different types of tubes (haven't had to buy any for YEARS), but I do believe that your 1100 needs TUBELESS tires.

I am running Avon road riders (tubeless tires) with tubes, which is recommended by many on this site. I want to pick up some extra tubes just in case I get a flat. I think the type (A,B,C,D) is something specific to motorcycle superstore as other places seem to use a more standard type (see below).

TR-87 stands for 90º bent metal stem

PV-78 stands for 90º bent metal stem

TR-6 stands for straight metal stem

TR-15 stands for "FAT" rubber stem

Yep, the 82-83 GS1100E came with tubes, for some unfathomable reason. Some people convert, some do not.

Anyhoo, you'll want the TR-6 valve type.

Not up to standards

Come on, boys! Surely one of you must want to tell him about the advantages and disadvantages between latex rubber and butyl??

There are a number of differences between the two (durability, porosity, elasticity, heat build up, weight) but I think the differences come into 'play' more with bicycle riders and us.

If you do a search here on the forum, you'll find a number of posts regarding the differences. If you do a Google search (or Yahoo), you'll find a whole lot of websites that address it.

I'm pretty sure most of the motorcycle tubes on the market these days are either natural rubber (latex) or a blend of latex and butyl. The vast majority seem to be latex.

Did a search and some tubes are stated to be "natural rubber". Does that mean latex?

[rockford]

Yes

I think so. I checked a few sites and came to the same conclusion. I saw mostly rubber (latex) and a few that were listed as latex/butyl blends. I didn't see any that were pure butyl but I think some of the bicycle tubes are, for sure.

I found lots of pure butyl tubes, including some high end name brand types.

Speaking of bicycle tubes, latex tubes are pretty much crap as far as I'm concern. They leak more easily and crack and age far more quickly than butyl. They have a more supple feel while they last though.

natural rubber tubes supposedly don't split in the same way the others can which means they behave more like a tubeless tyre when you get a puncture... (Go down in a slower/more controlled manner).

That is what I have read too. Is there any truth (science) behind this?

Have you considered going tubeless?

Worked for me. Tubes are nothing but a PITA. Requires a bit of work to make the valve stems seal correctly, though.

Tubeless / Tubes

If you do change to tubeless tyres be aware that the profile of the wheel rim is different for tubeless tyres – They have a bead behind the area the tyre lip seats so that if they spontaneously deflate the tyre is still held in place and you don’t end up running on the rim. Wheels made for tubed tyres don’t have this. Hmm, now that I write this down, using tubeless tyres on ‘tubed’ rims doesn’t sound anymore dangerous than sticking with tubes, does it (As I can’t see a deflated tube holding a tyre onto its seat)? Old tyre soap and corrosion seem to stick my bike’s tyres to the rims all to well, now that I think about it.
