I messed with my spokes ONCE, and stuffed it up. Had to send the wheel to Ash’s in Brisbane to fix it. Just sayin! 😎 I can understand that. The Ural manual says "check the spokes at 500km and 2500km thereafter" I assume this is a ping test using spanner/screwdriver or what ever. Not a torque test or NDT Cracktest. It is probably true to say the failure mode for cracks and split rims is over tensioning rather than under. That being the case. Is there a method to checking spoke tension by loosening and retightening in a diagonal pattern and alternating side to side on the hub? With tyre on and in situ. I know how Lee does it with the tyre and tube off. I would probably only need to do it once to establish a baseline. I did it both ways, including loosening and retightening etc!….The situation just got worse and worse and I gave up on it. Messing with the spokes with the tyre on creates its own problems because the spanner occasionally jumps on the nipple flats and rounds the flats out (the nipples can get real tight on the spokes), so your back to pulling the tyre off to complete the job which generally gets untidier as you proceed. If you HAVE TO, tap your spokes with your spanner and carefully tighten only that ones that are a dull thud instead of a ping. Personally I wouldn’t touch mine again dull thud or not, because that’s what started the first stuff up 30,000kms ago.😎

They really do require very little attention after the initial check. I always check mine when changing tyres. Just a ping test and stick it in the wheel stand if necessary for adjustment.

Yep I get it. I just want to be sure all the spokes are not over tensioned. A ping test will only make each spoke sound the same. If I get a dull one, that may be then get over tightened some more.

Like Wheels, I had a go at truing my spare and failed horribly. Took it to Chris Squires in Sydney to rectify my workmanship. When I asked Chris what ongoing maintenance was required, he said when you change the tire do the tap test and if they are really dull just nip them up. Same story from Ash's Spokes in Brisbane when they re-laced a cracked rim. I run a screw driver over the spokes when I have the tires off. No problems in the last 16,000 kilometres except another cracked 2015 rim - spokes sound fine on that by the way I know Ural say they have solved the cracked rim problem, but my money would be on inspecting the rims frequently while under warranty and not fiddling with spokes. Just as an aside, Ural seem to keep a lot of spare rims in the back of the shop considering the issue is solved

Thanks Andy. My thoughts are around firstly a ping test to confirm no loose spokes. Drive it up to the first 500k service. Then ping test them all again. If still OK, I would like to verify they are not over tight as you would assume they would bed in becoming looser. Loosen one and retorque to 5nm. Ping test it and compare with others. Like you, not 100% convinced the new rims have cured the problem. After all, we still have human error to contend with. eg Ivan has a hangover🤣🤣🤣
