Interesting video. Finding modern 26 13/8 tyres with puncture protection is an achievement in itself, which is why I considered using anti-puncture tape with older tyres, which I have plenty of. I do however have these tyres in the size of 27 11/4 on a 1970’s racing bike and I quite like them, no problems and not one puncture in over a year.
I have had a pair of Schwalbes, bought as a pair. One loose & one fitting fine. The issue with the loose one was only noticed a good while after purchase (it was sitting in the loft as a spare). Not only loose but ran out of true (tyre not rim). I was having to run at no more than 50 psi, but in the end that was too much, & ended with me having to push the bike 5 miles home. The wires hadn't come out, but the tyre could just no longer take any kind of pressure. And the moral of this story: any tyre bought as a spare, test it so you have the option of returning it.
I have Schwalbe Delta Cruisers on my vintage 60's three speed Raleigh sport which has both styles of rim and they tires fit well with no problem for many years now.
Great video Rowan, I too have had problems with Schwalbe tyres before but in 700c form. I had to take a set back to a well known car/bike shop recently with the same issue as yours (wires coming out!) I personally believe that there too soft around the rim and expand with the tubes to easily.
I've actually had similar problems but with 26" city slicks. Would never sit rite and seam would pop out. Kept trying to figure it out assuming it was my error. And when they'd hold they weren't straight had a wobble in the tread. . My guess is modern manufacture issues. This was late 90s? On a 1996 MTB. I've never over inflated.
I had a similar experience with Schwalbe Delta Cruiser (blackwall) tires on my 1979 Fendt Cardano. The bicycle is equipped with alloy rims (maybe Weinmann?) and had Continental "S" tires, which I replaced because they were beginning to show signs of dry rot. One Schwalbe tire came off the rim while being initially inflated, maybe 40 psi, and blew out the tube. I installed a new tube and very carefully reinflated, taking pains to keep the tire bead centered. I inflated the tire to 80 psi (it's rated for 60-85 on the sidewall) and went for a ride. At slightly over 7 miles, it came off the rim again, blowing out the tube once more. I had a a walk back of 95 minutes. I'm not sure if the tire will work at the traditional pressure of 50 pounds or so that the original tires were rated for, but it definitely does not work at the maximum rated pressure when used on these rims. Update: On 5/15/2023 I installed a new tube and carefully inflated the Delta Cruiser to 60 psi and went for a 15 mile ride, completed with no issues at all. I noticed when installing the wheel with inflated tire at 60 psi onto the front fork, the brake pads offered no resistance. When installing the wheel with tire inflated to 80 psi, the tire was fat enough that the brake pads partially blocked the tire from being inserted. So, perhaps on modern rims, the full 85 psi can be used, but on the vintage original rims on the Fendt, there is a partial incompatibility, and pressure must be reduced.
I got a set of those from a local shop and installed them on my '74 Sports. The bike has been upgraded to CR18 alloy rims, and with those, the bead seats well. The problem is that the Delta Cruisers that I have are fatter than typical 590 tires, so they barely clear the stays and fenders.
Rowan, I have also had similar problems with Schwalbes but to be honest, fining any 26 1/3/8 tyres that are narrower than the standard 37-590 is impossible. I have, like many other comments, resorted to replacing Raleigh steel rims, with alloy rims which works well but getting decent mudguard clearance with wider 590 tyres is a constant issue. Schwalbe do make a 25-590 puncture resistant tyre but its designed for wheelchairs, not sure that would be suitable....
I’ve got a set of delta cruisers 26 x 1 3/8 on my Hercules Commuter (Raleigh Built) they have done a good few hundred miles in all weathers and all terrain they have been fantastic just got Wilkinson’s inner tubes with their version of slime and had no punctures, they are however on aluminium weinmann rims as the original rims had rotted through. Usually at 40psi can I go a lot higher then?
There is never any need to pump up any tyre to 120 pounds per square inch! 60 to 70 PSI for a slightly wide bike tyre is ample pressure. By the way one solution would be to fit modern solid tyres to the bike. Like Greentyre or Tannus tyres. Which are made from hard durable polyurethane foam.
Greentyre and tannus are both absolutely awful and dangerous. I would never let a bike out of the workshop on them. The initial overinflation off the bike is an industry norm for seating the bead.
@Veolcipedium I was wondering whether the 120psi was a bike shop trick to get the tyres to seat - I was having similar problems with some mountain bike tyres recently and followed some online advice to that effect - pumped them up to 100psi checking the bead with every stroke until 'pang!' they seated themselves. Didn't solve the actual problem but it was the first time I had come across that technique!
Yes its an industry thing. Obviously the posted maximum pressure is a lawyer-induced thing, and tyres should withstand at least twice as much, unweighted. But of course that’s not made public because lawyers
