WorriedNoodle Posted May 10, 2020 Share Posted May 10, 2020 Bought some 29 x 2 mountain bike tires off of Lazada and been riding only on roads pumped up at 50psi. The tires have started splitting in places within 5 months of buying new on the outer edge on about 5 % of the tire with no bulging or effect on the ride performance I notice (photo attached). My other brand tires lasted several years and never split like this. This is the rear tire which is taking more weight, I weigh 88kg. Is this just a dodgy batch or a brand to avoid? Will I likely get a blow out and should change them immediately or are they OK to carry on with? Appreciate the advice guys? Link to comment Share on other sites More sharing options...
frequentatore Posted May 10, 2020 Share Posted May 10, 2020 (edited) Too risky to ride. What brand? I use 29x2.10 WTB Edited May 10, 2020 by frequentatore add 2 Link to comment Share on other sites More sharing options...
Crossy Posted May 10, 2020 Share Posted May 10, 2020 I would agree ^^^. I'm not a cyclist but a tyre with that much damage can't be far from failing. Link to comment Share on other sites More sharing options...

WorriedNoodle Posted May 10, 2020 Author Share Posted May 10, 2020 (edited) This is Chaoyang Falcon series of tire. Only bought the one so far (thought I got 2 but its only one so far). It was cheap and shipped from Thailand. Looked on Lazada and that supplier no longer exists but plenty others on there. I may try another as they are so cheap.

Probably manufactured 5 years (or more) ago. I had a tire from Decathlon that did exactly the same, but my previous purchase of the same tire is still perfect. They replaced it with another which is fine. Edited May 10, 2020 by BritManToo 2 Link to comment Share on other sites More sharing options...
Relocated Posted May 10, 2020 Share Posted May 10, 2020 Reduce your weight down to 78 Kg and see what happen. 1 Link to comment Share on other sites More sharing options...

I looked at the tire markings, there doesn't seem to be any code on the side indicating age like you get on car tires unless I am mistaken.

rvaviator Posted May 10, 2020 Share Posted May 10, 2020 Poor rubber composition - Could easy be an issue with heat. The rubber is too soft. Try a different brand Link to comment Share on other sites More sharing options...
n210mp Posted May 10, 2020 Share Posted May 10, 2020 just a thought 50 psi sounds very low, is this the pressure recommended on the tyre wall? Link to comment Share on other sites More sharing options...

WorriedNoodle Posted May 10, 2020 Author Share Posted May 10, 2020 I have bought another tire to replace it from Shopee this is also Chaoyang brand but this time its a Merlin type which has a different tread on it and looking less likely to split along same lines as the previous Falcon. If that fails the same then I will only buy more expensive tires in future. When I received the Chaoyang Falcon tyre it looked is very good condition and the cracks happened over time after 5-6 months. The 50psi I use is exactly what is labelled on tire, so pressure and weight limits all within spec, must be a dodgy rubber composition I guess.

bobfish Posted May 11, 2020 Share Posted May 11, 2020 Agreed, 50 psi is the max rating. Depending on the tyre width I'd be running 30-35psi, and less off road. Link to comment Share on other sites More sharing options...

PSI depends on tire width and load weight. A 2" tire is good at 50 psi, a 1" tire would need 90 psi. Link to comment Share on other sites More sharing options...
SteveK Posted May 12, 2020 Share Posted May 12, 2020 (edited) Chaoyang tyres are good, and exceptional for the price. They manufacture for some of the more well known (expensive) brands. If you got 5-6 months use in hot Thai weather and only paid a couple hundred baht, then I don't think there's much to grumble about. Either an old tyre or a manufacturing defect, life goes on.
