I’m currently trying to set up a second set of wheels for my Secan, got one set for gravel and just got another one for road / commuting. I’m putting a set of 38mm panaracer pasela PT tyres (not tubeless ready) that i had already on new hunt wheels and the tyres have been very good winter / commuting tyres on another wheelset but have only had them with tubes till now.
One is almost new and one is 70/80% used so should be good! got them all seated no problem and sealant in. when they’re inflated the sealant fizzes out the sidewalls and the tyres won’t hold pressure. I’ve had this issue on some wtbs before which eventually sealed after a few weeks and a lot of sealant, presumably once a layer has built up on the side walls. These ones I’ve added more sealant and inflated several times now and it keeps happening……
As I’m now too tired/frustrated with them to make a sensible decision I’m throwing it out here so shall I……
A. take a breath and persevere
B. buy some new tubeless ready tyres Gravel King SS+ and start again
C. fit tubes
