After buying a third spare rear wheel of e bay have decided to fit a CO2 to go with the MT43, MT21 and Motocross knobbly I already use but unsure of what pressure to run it at, any advice from those who are regular users of the CO2 would be great as have never run one of these before have also heard that I have to scrub it in for a hundred miles or so is this the case?

14-15 psi for me and yes they can be a bit tricky on the blacktop for a few miles to start smile

Thanks jt around about what I would have put in it smile but I always seem to run a couple PSI more than most just to stop the pinch punctures. Is the co2 the preferred choice up your way?

jt · Powermonger!!

Yes, but I'm currently trying a Mitas 644 Army special and its very good.

CO2 on the rear =12 psi

Even got up devils steps no badgers :)

I'm on my 3rd CO2, brilliant tyre, I ride with 12 psi.

In 2 years , on a TTR250 & now a WR250R i've not had a pinch puncture...........

That's probably jinxed it

Also, yes they are interesting for a while but they get better & better as they wear.

Ah, but you only weigh about 2 stone!

I use 18lbs (and weigh a packet or three of Opal Fruits over 17 stone) and haven't suffered from lack of grip - other than on some of those gnarly slate lanes oop Norf disbelief

great tyre, i find that they are lasting to 3 of my usual tyre(mt21), absolutely awful for the 1st hundred miles until you scrub them in thou!

between 15 and 20 and you will not get a pinch puncture!

They do wear well! Try as I might, I can't wear out mine and it stays at the point where it is just a tad too good to replace confuse

Thanks Guys hope to try mine out on a little evening run next week

wackyracer · Powermonger!!

28 PSI and i'm excited biggrin biggrin biggrin

Yeah normally run about 14 psi

A good tyre to ride up simms in the autumn with a few leaves in the wet - interesting to say the least biggrin biggrin

Hey Russ, I've just started running a CO2, the first couple of rides I thought I had made a huge mistake but now its scrubbing up a bit I'm well happy with it, seriously though they are scary on tarmac when new, especially if your trying to stop/slow down on a hill , I run mine at around 12 psi.

Have fun buddy.
