Road tubeless tyres, where and how much?

Did you over tighten the valve or collar when setup initially? because if you do it can damage the plastic piece on the valve and maybe cause an issue afterwards.

Moved to Orange endurance sealant here, supposed to last a long time and seems to work well.

Patched... and broken my Stans injector... so from now on back to filling with a funnel

Been riding Hutchinson Fusion 5 Performance tubeless ready since May. Everything fine until today's ride when a large blister, about 12 mm diameter, has formed on the sidewall and little bit onto the tread area. The tyre is still fully inflated, the pressure in the blister is obviously a lot less than in the tyre and when I partially deflate the tyre the blister does not change, so it seems it is not connected to the main air volume. Thinking this is a manufacturing defect, possibly separation of some layers in the tyre or of the sidewall material from the tread material. Doubt it has anything to do with the hot weather as I was home by 8 am. Anyone got any ideas before I try a warranty claim?

Blister similar to this? https://i.imgur.com/AwoiZ6m.jpg
Had that happen on Mavic Yksion Pro tubeless tires which are made by Hutchinson and got a replacement from the local distributor as Mavic informed me it wasn't safe to ride.

Thanks for that. Almost identical. I guessed that it isn't fit for use any more, just need to try to get a warranty replacement now. Done 590 miles.

Yeah same mileage here when it happened. Now using Galactik's and so far they haven't shown this issue but they cut from the first few rides (it's a racing tire).

I thought the Galactiks looked a bit fragile for the rough,debris-strewn roads around here, so went for the Performance as a middle ground between the All Season and the Galactik. Apart from this blister hardly a mark on them.

:shock:

The orange endurance stuff comes with a straw thingy that goes nicely over the valve top, no need for the syringe. I marked 1 oz lines on the bottle which is clear (8 oz bottle), so turn upside down and squeeze until an oz or so has gone in.

zefs

You can also use a syringe from a pharmacy.

600km Audax completed in 30+ deg at the weekend, melting tarmac etc.

Good few miles coming onto the Roadlites now, performance is excellent and they still look new, not a single mark or cut on them.

Easy question, think I know the answer. My tyre went flat after a ride, pumped it up and it last around 2 hours before being flat again. When I put it in the bath, air is coming from at least 4 spoke holes. I'm assuming the rim tape has somehow randomly lifted and I need to re-tape? If so, any thoughts on the best tape?

drlodge

I'm using Tesa rim tape as suggested by Ugo, just looked on Malcolms website (TCC) and he shows it too.

Is there anything better than IRC Roadlites? I currently have these in 25mm flavour mated to some of Malcolm's tubeless ready carbon specials. They only come up as 25mm and don't find them anymore comfortable than my winter bike with Conti GP4k's which come up as 28mm (25mm's on wide rims).

What I do like about the IRC's is they (touches wood) seem hard wearing, and apart from one quite major puncture in the side wall (fixed with a patch), have been relatively trouble free.

I was thinking of ordering some them in 28mm, but before I do, was wondering if there's anything comparable that don't cost £55 per tyre. I riding buddy of mine has Schwalbe pro 1's on his bike and he's been really unlucky with punctures, so not that keen on them.

Anyone, Bueller.....

Maxxis Padrone around £35

I'm pretty sure you can't get the 28mm flavour for £35.. £40 wish more like.

You ride these Slop? You like?

I was looking at the Hutchinson Fusion 5 Performance. They seem to be around the same price.

Avoid Hutchinson, in my limited experience

What pressure are you running them?

I've got roadlites in 23c on two bikes, I weigh around 80kg and pump them up around 90R/80F and find them very comfy. Might be something other than the tyres?

I think I weighed 80kg at birth. Haha!

With my Conti's I'd run them at 60/70psi. The IRC's I find 90 is optimum for me in terms of handling, but I feel every lump and bump in the very sh7tty roads where I live. 70/80 seem more comfortable, but I find cornering feels a bit 'squidgy'.

I had an interesting failure this week.....

Swerving to avoid a nodder who about to crash into me I hit some kind of solid object with my rear wheel and instantly lost a lot of pressure.

I stopped to investigate, tyre was absolutely pristine, no cuts or obvious issues. No sealant spraying over my frame. As i'm fiddling with my CO2 pump I notice that fluid appeared to be leaking from the spoke holes... and not just one of them, ALL of them.

So it seems the bump on the rear wheel was significant enough that it's caused the rim tape to blow out and force sealant out through the spoke holes.

Fortunately this was the last 5 mile of a 200 mile overnight stay. Also fortunately after my second CO2 cylinder it held enough pressure to get me home, and the pressure stayed up overnight. So it wasn't totally catastrophic.

I will get the tyre off to investigate tonight but that seems to be the only explanation.

cycleclinic

if it is the tape then there must have been air trapped under the tape.

I do have 23mm roadlites back in I think as well. The problem is not the tyres its the roads. 2.0" tyres are the solution. The number of people breaking stuff on the road is not assuming.

Hi

Have just started a new contract and am commuting to work 2/3 days per week (its 60m round trip so 5 days a little too much at the moment). Route is mainly B roads of varying quality but there is approx 5m on a sustains cycle track. Am going to be buying some new tubeless compatible wheels shortly and want to get a set of tyres that can cope with the commute but also durable and ride well (currently running GP4000 II) in a 28 width on the rear (front 25) as don't want to be changing wheels/tyres when out on the Sunday ride.

What would forum members recommend

Cheers

Depends what wheels you buy. Some of the Mavic tubeless wheels come with the Yksion Pro UST tublesless ready tyres and so far I can't fault them.

cycleclinic

The roadlites need around 80psi rear min to feel right in 25mm firm at my weight.

Oddly though the formula Pro tyres in 25nm are smaller at 25mm wide and 22mm tall but at 80 psi rear they are as comfortable. The roadlites will be less aero too as it's too wide for the rim really which is why most folk go for the 25mm formula Pro tyres.
The 28mm formula Pro tyres can go as low as 60 psi and still feel fine. Therefore comfort on these tyres is good.

The only other tubeless tyres I have some success with are the Mavic yskion UST tyres. They wear faster and cut more and I have been let down a couple of times too. They quick and fairly grippy though. Comfortable as well at 60 to 80 psi for the 28mm tyre.

So i took the tyre off, rim tape shows no sign of being compromised. The original factory DTSwiss tape was pristine and the additional later of tape I added was also fine.

The other culprit looks to be the valve stem, lots and lots of sealant build up around the seal and the rubber part of the stem looks a bit knackered so it looks to be a pre-existing issue which blew out when i hit an obstacle at a decent clip.

Strange one.. I'll retape and refit with a new valve stem and hope for the best.

BTW I've been using Stans stems. I thought they were ok but I think comparing them against the DT Swiss stems, the DT ones look to handle being tightened down much better, the rubber is much sturdier compared to the Stans.

Tyre failed at the bead on my rear Hutch Fusion 5 Performance, pretty spectacular bang and only a few miles into the ride.

I'd topped up the sealant for the first time yesterday - I don't think I'd even had a puncture on it yet, might not have even done 1000 miles.

Pretty unimpressed to be quite honest. Tyre was at 120 psi, max recommended is 115psi but you'd have thought it'd be within the margin of error - certainly wouldn't expect spontaneous failure, especially on such a new tyre.

Bought back in November so warranty probably a non-starter (especially as I binned it).

Had to call the support vehicle to deliver a new tyre.... fortunately the ride was without incident from that point onwards!

sloppyschleckonds

psi sounds very high for tubeless

cycleclinic

Way too high. Try 80 max. Also what rim. Some rims bead hooks are too sharp and don't point up enough making failures like this more likely.

Hutinson are made for the Shimano/campagnolo tubeless standard. Mavic UST and kilin match that very closely.

timothyw

XR31t rim. Pressure certainly high but I'm a heavy chap - 120kg - it hadn't seemed unduly harsh at that pressure.

I'd suspect 80psi under my weight would feel very spongy - the tyre itself had 100psi recommended written on it (it's a 700x25)

Going back to what I said about topping up the sealant, I'd been running it on about 115-120 psi on the commute and been finding that the next morning it had dropped down to 80psi, which was part of why I was inclined to run it on the high side for the big ride - didn't much fancy having to top up on the ride if it was still losing air.

imafatman

You should honestly try some 28's at that weight. I was much heavier than you and only ever went to 90psi at most, and now ride them 70-80psi without feeling spongy.
