Tire wont seal.

[Neg]

So went for a quick ride yesterday. and this morning the tires are still pumped at 2bar where i left them yesterday. looks like its sealed, but for how long we shall see... :)

Now that you have done the conversion, what pressure are you going to run your tyres at? Will they stay sealed at a much lower pressure?

[Neg]

Not sure Yet, but when i was running tubes i suffered badly with snake bites at anything below 2.8 at the rear and 2.5 in front. my weight plays a role here too. (110kg) In realy rough stuff i needed to go to 3 at the rear and 2.8 in the front.

 

Yesterdays ride was sedate and slow and i stayed off the rough technical stuff... bike felt nice at 2 bar though, so i might test these pressure and take it from there. Most guys are on like 1.5-1.8 bar on tubeless? i know a bit of a generalization, though research indicated that these are the pressure used... but that's sub 100kg guys... im heavy and ride very hard so i think i will test 2 bar first, if anything i will go a touch harder, maybe to 2.2 all round. still down from 2.8 and 2.5.

 

dont know if they will stay sealed at lower pressure... like i said, when trying to seal them i tried high pressure and they went flat, lower pressures just to get the sealant working.. went flat... but when i got to groenies, i set pressure at 2bar down from 2.5 and they seemed to be sealed now... but will keep an eye on them.

Once the tyres have sealed they will stay that way . But common sense should be used as well . You cannot expect the tyre to stay on the rim if you run your pressures to low .

Hi Neg

 

I am a big guy as well (95-100kg)

 

Currently I am running like this;

1.7bar F

1.9bar R

and never hit through to the rim.

Once the tyres are sealed, they should stay like that, sealed.

 

Also depends on your type of tyre (some have more volume, if you look from the rim out to the rolling surface).

 

Be warned of tyre burping and the carcass coming off the rim at low pressures.

 

How did the tyre mount the rim before you started the tubeless setup?

What tyre and rim are you using?

Because some tyre beads and rims just work better...

wrt to the tire coming off the rim, this is why i dont wanna ride a pressure that too low.... and the main reason is that im NOT using proper tubeless tires. im running Schwalbe's Racing Ralph's ( i thought it was Rocket Rons but was mistaken) 2.25's i think. was using tubes with slim in.

 

These tires HAVE seen better days and its what i have so i have to use them... i am using the Std rims that come with the 2012 Giant anthem X 0, PX-2 i believe??

would LOVE to get a proper tubeless rim set but alas... not in the near future...

 

my next move will be to get new tires- im thinking Maxxis Ikons or GearX Saguaro's?

also, since taking out tubes and slime, i reduced the weight of my bike by 800g. added sealant and it came down to about 550. so half a kilo off. i know is not worth anything and tubeless conversion is not a weight saving exercise, but im happy with the weight loss. with new tires i should at least be back to where i was...

side note, switched my ladies bikes wheels to as set of Fulcrums red metal 3's (26") and we took 2kgs off her bike. (also the reason why i wont see a new set of wheel for a while)

Try valves with a bigger base?

 

I have P-XC2 rims with Stans tape, and Cafe Latte valves, had no problems with the following tyres in sealing:

-Racing Ralph Evo (crap sidewalls)

-Maxxis Aspen Folding

-Maxxis Aspen Exception Exo Protection (great)

-Maxxis Ikon Exception Exo Protection (best overall)

-Continental Raceking Protection (crap sidewalls)

[Neg]

Yes, those are the rims i have!

so you say the Ikon's work well? and how is their grip etc...??

[jannosmit]

Ikons - you have to get the Exo Protection version

Grip: very good, good all around tyre

Weight:580g

Price: +- R550

 

I've been up corners and angles that I don't know how those tyres grip, awesome.

Cool, i will check into them?

how about the gearX? do they seal well? anyone know?

Silence = Get some Ikons!

[Neg]

Shall do!
