Just can't get my tyres to sit right ! Anyone got a SIMPLE FOOLPROOF way as it's doing my head in !!

i've got BONTRAGER 27.5 tubeless rims with BONTRAGER tyres but using tubes. I took them off to try some other tyres but didn't like them so, SIMPLY, trying to put it back how it was.

Bit of washing up liquid round the bead then pump up til they pop into place.

I've got a 1kg tube of tyre fitting soap and a stiff brush. Never have any bother, but pretty much any soap will do.

I have even found just putting water on the bead can do it but soapy solution will be more guaranteed to work.

I saw a useful Youtube vid on precisely this.

Bontrager are particularly bad for it, some sort of lubricant is a good shout.

Cheers guys, that sounds good. Hey Billmc, you can't find a link to that YouTube clip can you ?

Assume you mean how to get them so they're radially concentric to the rim...
Bugs me too. ๐Ÿ™‚

I've a gap between two paving slabs. Put about 10psi in then wedge the tyre in. Then flex the tyre side to side till it sits concentric. Then pump it up hard, 40psi, overnight.

If this sounds like the actions of a nerd, I apologise. ๐Ÿ™‚

Get about 10-15 psi in, then work around the rim giving it a good hard massage from both sides. May also work for a lover.

Haha...loving the OCD on this thread!...to be honest it bugs me when i look down at my front tyre and its not seated 'straight' on the rim too...as it rotates it gives the impression the wheel is buckled, which it isnt obviously but i find it distracting for the rest of the ride and usually end up buggering about with it when i get home....i still use tubes so i put the tyre on, pump it up a few psi then squeeze the tyre away from the edge of the rim all the way round. add a few more psi, squeeze tyre together between my hands and away from edge of rim again....repeat until you have the desired pressures and the tyre will usually sit straight.

I'm sure having the tyre not quite true on the rim isnt an issue performance wise but again the OCD part of me tends to think that the tread isnt quite hitting the ground perfectly as the designer intended it to and bizarrely enough this does then play on my mind and hamper the way i'll ride and the speed i hit stuff....all psychological i'm sure but tyres are my nemesis from a psych point of view and stems from my motorcycle days when a crappy set of tyres was instantly noticeable and borderline dangerous to ride with....obviously things arent that dramatic with MTBs but old habits die hard!

Bonty tyres and rims can be a nightmare to seat. Lube the tyre and pump it up to 80 psi or less if it pops into place earlier . We have a park tool for seating tyres but sometimes it still needs a good wrestle to get a tyre to seat.

Thanks again for all the response. Glad it's not just me !! It's just stopped raining so I'm going to give it ANOTHER go.
I was pretty sure I'd seen a tool for doing this somewhere so I might check out Park, thanks Neil
