Tubeless tyres on normal rims


slabs

Recommended Posts

I have heard that you can put tubeless MTB's on rims that have had tyres with inner tubes in the past. Have even heard that there are people that have done the Sani2C and Epic with this conversion.

Anyone done it and what has the experience been. Do not want to buy tubeless plus new rims to fit them...

Of course you can, easy as pie.

 

I think most MTBers on this board that have converted to tubeless have "normal" rims as opposed to tubeless specific rims.

 

Any tyre will work as well, doesn't have to be tubeless specific.

1 x heavy rider; 1 x conversion kit on 'normal' rims; 3 x years without a single puncture.... Joys of joy...

And this from a man who used to puncture every, but every week... Censored

I did the conversion just over a year ago. Ordinary rims. Kenda Karma tyres and Stan's conversion kit. Should have done it years ago.

With UST tyres on normal rims you don't need a Stans kit.

 

Just one layer of fiber strapping tape, and 2 layers of electrical insulation tape over the spoke holes and a tubeless valve. I use the long valves of road bike tubes... just rip one out of a thrashed tube and put a 3x3mm o-ring around it... 

 

The UST tyre sits tighter and have a thicker bead... seals very easily...

 

With non UST tyres, use the Stans srip, even though tape works, the strip makes them seal so much easier...

Haven't had best of luck with conversion kit. NOt that it doesn't work, but when you puncture that little freaken strip you place over the nipples attach to tyre. Freaken mission to seperate the 2, especially on the trail. Then 10 out of 11 times you sealed glues the tyre walls together - only happened when I used that grey liquid in yellow bottle.

 

Long and short of it. Use conversion, just make sure your sealant is topped up!

I use standrd tyres (non ust) on standard rims (mavic 317).They are tubeless and done San2c and many other races on them. have fitted Michelin xc dry tyres and Maxxis crossmark (the ones with the steel wire in it, price R180 per tyre) On them. I havent had a puncture yet(used for 8 months now). I have the stans tubeless strip in them with some fibre reinforced tape under the strips to seal the spoke holes)

mm.. WHY AM I THE ONLY ONE THAT SEEMS TO BE HAVING BAD LUCK!!AAAAAHCry

 

I use to ride a maxxis crosmark lust on  the back and a normal kevlar on the front. didnt have punctures for Yonks.. I swapped to WTB with Protection "armour" wall and Ive had 3 Punctures in 3 5 rides. The first I pinched both casings! front and back!

 

Anyway. I think Im just having bad luck. If you ride agressively and/or consider yourself a heavy then think aboout getting Proper UST tires.

 

But rims- dont bother.
