I've always used Stans "normal". It's always worked. Never seen the need to try anything else.
Other than when its a few years old...
Yeah my MTB tyres with Stans in lose 2-3 psi over a couple of weeks which is fine but these tyres/wheels are losing 5psi overnight. I only swapped to MucOff to see if that would cure it but I think I'll swap back to Stans.
Is this normal? Will it just seal eventually or should I be returning the tyre for a replacement – bearing in mind it’s only a week old.
Normal to begin with and sealant will fix it. Suggest using a different sealant to the mucoff you have in there, or trying a mix of artshop latex (£10 per litre on ebay) diluted 50-50 with water. Stans is usually good though.
My experience with Specialized tyres has been consistently good and if you're using Specialized wheels too all should be fine so I'd try a different sealant first. (edit, as you said .. oddly the last few posts weren't showing when I replied)
I've dumped Muc Off sealant, after too many issues where it either wouldn't help seal up a new tyre and failed to stop issues on a ride.
Spoke to the LBS, who mentioned that it is the only Muc Off product they don't stock, as they don't rate it.
Stans or Peaty's stuff seems to work well.
I think I've found why Peatys sealant isn't quite as good as Stans - I took a freshly installed tyre off to change over and Peatys had coated the whole inside of the tyre. Stans sits more in a puddle that rotates with the wheel - so if you get a hole, there's more of it to fill the hole. The peatys is so spread out that it can't "flow" into the puncture as well.
Mavic's stuff I've found is more like Stans and has worked well in my road tyres.
I accidentally bought a big bottle of Continental (confusing it with Mavic, I think) - not sure how well it'll work, but it does rather congeal in the bottom of the bottle and needs a good shake before installation.
Right - swapped back to Stan's. Initially it’s bubbling out of the side walls so I’ve left it lying on each side for an hour or so and spun it around etc and now it’s back on the bike. Pumped up to about 60 psi and I’ll leave it like that overnight, hopefully the Stan’s will seal it.
My question remains though, is it normal to have air coming out of the sidewalls like that on a £55 tubeless ready tyre?
Not in my experience, no. In the old days, when you were trying to get tyres to be tubeless or when using racing tubeless tyres, sure, but I’ve not had that on any recent road or gravel tyres. But I also don’t wash/scrub them before use.
Good picture.
The Swalbe tyres that I have on do exactly the same thing but through the tread.
No sign of any sealant leaking through, but the soapy water found it.
I'm loosing about 5 psi overnight from a 35psi pressure.
In my opinion, I just dont think these tyres are good enough for the job.
(All my trials and tribulations in the thread 'I'm Giving Up'.
I’m going to take them back to the shop if they don’t seal tomorrow. I’ve faffed about with them for a month now and now I’ve discovered it’s not leaking from anywhere I would have expected and leaking enough that it needs topping up with air mid ride if you want to keep it at a certain pressure it’s quite frankly bollocks.
These are Specialized Sworks tyres and I read somewhere they make the sidewalls really thin to save weight 🙄
Spesh are the only tyres I've had that sealant has bubbled out of the sidewalls. Only ever use the Grid version.
Lbs have given me a new tyre . Will try that tomorrow….
Fixed!! Hurray!
So I put a new tyre on (supplied by my lovely LBS in exchange for the leaky one) and went for a 60k ride on it today and hey presto no more loss of pressure (well 1 psi over 24hrs but that could be temp fluctuations and the fact that it's newly on and only one ride old so meh 🤷♂️).
😎👍
Name the shop and give them some credit!
Infinity Cycles in Durham. Brilliant store - built me wheels, sold me a fantastic bike. 🙂
Yes, they’re great. Bought my kids Whyte 405 from there and they were very helpful.
