do not for the love of god do this!* check your rim first as they have handy max pressure settings, 40 psi plus on most modern tubeless rims, will have you covered in spaff, deaf and wondering why the surrounding area looks its been visited by a crack squad of bukake ninjas

*this is also the reason a lot of people say that tubeless systems are crap etc.... the lack of blokes reading instructions is amazing

Not sure about this and for me it's got nothing to do with losing air but my WTB tyres are bleeders to seat and I need 60-80psi and lots of soapy water on the beads to get them seated correctly. The LBS even needed 100psi to seat them first time tubed and Hope (XC rims) advise that this shouldn't be a problem as long as they're not ridden at this pressure; they recommend 60psi max ridden whether tubed or tubeless.

It's probably a good idea though not to over pressurise tyres either to seat them or test for leaks with fluid in them in case they do blow off the rim!

Extra sealant on new tyres is worth a try too just to seal up pesky leaks.

Just ride them - the seal improves with use to a point where you may/may not notice any pressure drop.

IMHO, it's better if the Gorilla tape does go up the side of the rim a bit, but they're holding air now, so leave them alone and give them some use.

My pre xmas pair now go flat in ~48 hours. So i'll be whipping them off when all the fuss over xmas dies down, and scrubbing the bastards. Every other tyre i've done over the last ~10 years i've scrubbed, and they've all worked really well (lose ~5 psi/week)

The lack of blokes reading the original post is also alarming, the OP stated they are using a Shimano MT68 rim which has a max pressure of 58psi and a Smorgasbord tyre which can go up to 65psi. I'm not advocating keeping the pressure at 40+ but have found this method works on non UST tyres.

OK some, the more common ones

velocity give a max of 45psi to tubeless

WTB rim user guide again gave 40-45 as the absolute upper pressure from memory

so up yours with half a bottle of stans and homemade fire extinguisher air reservoir poddy :)

Most?
Drivel.
How many have you set up in the last month? :)

That's just made my day! Cheers tazzy :lol:

I once walked past a road sign that had a small sticker on it that simply read 'Bukake ruined my carpet'.

Dunno why or who put it there but they deserve a pint.
