Tubeless loosing air!

[TrailWarrior]

I acquired a new set of ZTR Arch Ex wheelsets. They run Stans No Tube.

I had proper tubeless (LUST) tyres fitted by LBS and have had them for 2 weeks , not ridden yet. The problem is first it was the rear wheel then the front wheel that went flat over 4/5 days.???? Wheels were rotated daily. Really frustrating!! never had problems with any other fittings of tubeless over the past 2 years.

 

The question on observation is this:

Okay the LBS went and used Joe's No-Flats tubeless kit. (I only use Stans)

The second thing is that I notice the rubber rim band protrudes over the lip of the rims on both sides once the tyre is fitted by +/- 3mm either side? Is this right? (never seen this before)

(Should the tyre beading not have any obstruction between the tyre bead and the beading seat on the rim?

I do not see any signs of sealant spillage or leakages on the rim or via spokes.

 

Be interesting to get some feedback.

Pump them up, Spray a mixture of dish liquid and water around the tyre, between the tyre and rim. You will find out pretty quickly where it is leaking from.

all stans wheel are tubeless as far as i know, in which case you don't need the conversion kit, only rim tape and a tubeless valve. http://www.notubes.c...-Rims-C119.aspx

 

if i am understanding you correctly the conversion kit is causing the tire not to seat properly and you are not getting a perfect seal. so rip out the conversion kit get some rim tape and valves and do the following;

 

step 1 Taping & Valve install

or use this method which works just as well and is a wee bit cheaper.
