“Gravity. Left the house with about 28psi in it and it rolled on the first proper berm. Bead popped off and that was that.”
You clearly shred the berms quicker than me! Is it a bad tyre:rim pairing? It’s pretty chunky casing, Kevlar bead and 28psi isn’t exactly low pressure (if your gauge is accurate).
Standard bike fresh out the shop with some kind of Roval alloy wheels. I assumed they'd be a perfect match. They were really easy to set up initially but it was hopeless when I got home. It took a few attempts with the compressor to reseat it and it was still flat the next day. No chance of doing that with a mini pump. I was going to go looking for a leak in the tape but it's sitting at a steady pressure now.
I was riding Wharncliffe. I don't know my way around very well but on the man-made stuff there's lots of tight berms, steep chutes, compressions etc. Its quite easy to deform a tyre but I've never had a problem with my Continental's and I've ridden that bike much harder than this one on dozens of uplift days.
Rimpact inserts are in the post. Currently 30% off on the website if anyone is interested.
I'll persevere with the tyres for a while. I might even try a Hillbilly T9 before I fully renounce the big S again.

Take the rimstrips off and put a couple of layers of rimtape underneath then re fit the strips.
I've had burping problems on the same rims.
Tried a Kryptotal instead of the standard Spech tyres first and had the same problem.
Added the tape and re fitted the Spech tyres and it's been fine since.
Thanks, I'll definitely do that before I spend big money on tyres.
I dented the stock Roval rims within a couple of rides and put Rimpacts in at that point - it was the depths of a muddy winter riding local trails so no berms got ridden hard before the inserts went in. I’ve gone insert-free on that bike recently but it’s got EX511 and EX471 rims and DT Swiss seem to know what they’re doing!
Another day, another failure. This happened in the road about 3 miles away from home.
I don't know if the problem is the Roval rim or the tyre but something is going in the bin.
Luckily I had a Rimpact in today so I just pedalled it home. Bloody grim end to a decent ride though.
That’s shit! At least it was at the end, not the start, though!

I've had zero problems with Spesh tyres and (carbon) Roval rims with cushcore. Now on Kryptotals with no cushcore and seem ok so far.
What I did notice though when inflating to 40+ psi, the bead seating with a 'pop' - as soon as I let the air out again, the beads left the rim, whereas other tyres on other rims would stay in place. But I'm new to all this tubeless nonsense. It could be more the evil tyre to blame than the rim in my instance
I had butchers fitted on my levo and kept them on till they wore out, never felt as confident on them as I did with MAXXIS or wtb. I really wanted to like them and even concede a bit of grip but now the rear has worn to the point the knobs are all undercut it’s time to replace them with a tried and tested combo. For what it’s worth they were used on everything from loamy trails to rocky trail centre to clay. They really didn’t stand out on anything. Sadly tire experiments are expensive
