Spare tubes

[pete-blen]

Just wondering if its possable to get a
19" tube to fit both 18" rear & 21" front wheels?
Trying to get out of carrying 2 tubes on the bike...

Just carry a 21" tube mate. You can use them in the back no problem short term, just put 30psi in.

hmmm. Im not sure.
But you need to update your info details thingy....as im guessing you are no longer talking about a VTR 250. (Grats!!)

ClintA 21" fitted in the rear will get you out of a jam but the are known to fail quickly because they are stretched way to far.

[Woodman]

Just carry two in my opinion.
If you put the right tube in out in the field then you won't have to do it again when you get home.

[warewolf]

You're more likely to carry a less bulky and heavy 21" std tube everywhere you go, than having one of each left behind because it's too much. Unless you are talking about a RTW trip into no man's land, your "everyday" field repair kit should be as light and simple as possible, so you'll carry it. It's only "get you home" gear & tools.

[gav24]

Yeah, has to either be the 21 or 2 tubes.
a 19' will fit in the rear OK for a short while, slightly easier than the 21', but wont fit the front easily at all. It will pinch so many times, you will go mad with frustration:crybaby: and wish that you'd just carried the front and rear tubes.
I would just bring a 21 if it was me for a day or 2 ride. Any more than that (or that far from a bike shop) and you may want to take both...just my opinion:scooter:

I'm with this guy. A couple of tubes isn't that much to carry. :yes:

[gav24]

If you're really worried about not carrying too much - do what I really do...
Ride with others who carry enough gear, and bring beer in the luggage instead:drinkup:
You can either barter with it for spares and tools alng the way, or drink it when you get there with the smug satisfaction that your bike is so reliable:yes::facepalm:

[Pikey]

Bugger I thought you had the tubes and tools with you:Oops:

[XF650]

My spare tubes are somewhere between Hinds & Temuka........

[thepom]

I carry both in a pouch over my front guard....

That's what I thought until I put one in the back just south of Clark's Junction one time & didn't get around to swapping it out until 1500km later at home :shit:

Another point re tubes for n00bs, swap your std ones for heavy duty, carry the std one for a spare as it takes up much less space. With that level of preparedness Murphy will storm off in disgust & you'll probably never have a flat anyway.

.... and to throw petrol on the fire Murphy will ensure you have a flatty in the bottom of a gully, far away from a flat warm dry quiet non windy easy place so I reckon get the correct gear and do it once and properly rather than double doing everything.

If you are really worried about weight, get your fat arse to the gym or have a huge dump before you ride :facepalm: :lol:

or you can go tubless :whistle: & carry beadboots or just find a place out of the way for ya tubes & attch with sip ties

I've done that (we fixed up a rental bike for a guy on a ride, who returned the F650 with 21' tube in the rear tyre). However, I'm not sure that it would be a good idea on my 950 because of the size of the tyre and also because it's not the sorta thing I wanna do twice.

[pete-blen]

thanks guys....
now while on the subject of tubes... AIR
dose anyone use the 12gram CO2 inflators..
if so how meany powerlets are required to
inflate a tyre..
I know that will change as CO2 is very
temp sesitive...

Are 12gram the larger ones?

I use those, and it takes two or three to inflate a 950 rear (5.00/70x18).
It's damn near impossible to bead the tyre with shitloads of CRC, and a lot of kicking and swearing.

[Monstaman]

In the field the armstrong action with bike pump works the most reliably, in the garage the air compressor for sure with a bit of temporary over inflation.

Two minutes on the road and the gyros with seat your bead if you can't in the shed or in the field.

[warewolf]

However, I'm not sure that it would be a good idea on my 950 because of the size of the tyre and also because it's not the sorta thing I wanna do twice.That is a fair call. Given a) the size differential between the front and phat rear on the twin, b) the difficulty of getting the fcukin tyre off & on, and c) the extra mojo of the twin stressing the tube/tyre... carrying the correct rear tube is a smart idea.

Different story on a mid-capacity single though. The second tube would add 50% to the bulk of my tools/spares, for little discernible benefit.

[Skinny_Birdman]

Just carry two in my opinion.
If you put the right tube in out in the field then you won't have to do it again when you get home.

Hear hear. Fortunately, you can fit two tubes (and almost all the rest of your tools) under the seat of the tranny.

[Shewolf]

I have tyre levers, a spare tube an air compressor and my AA card - think they'll come and do it for me in the whops?

I've seen tyre changing done on You Tube :innocent:
