Road tubeless tyres, where and how much?

MisterMuncher

Anyone seen the Vittoria Corsa TLR outside a press release? I'm a devil for a bit of skinwall, and Pro Ones seem thin on the ground.

So Mr Ugo, any ideas on how to get these bloody tyres to "pop" on the rim? I've used a slightly diluted washing liquid solution on the beads/rim and have an air compressor...air is going into the tyre up to about 50psi but its leaking between the tyre bead and the dips in the rim tape where the spokes holes are (perhaps not helped by my offset spoke holes). It would seem you need quite a high pressure *and* high volume of air, more than my fairly large compressor can put out. I even removed the valve core so as much air as possible goes in. I might try the local Sainsburys garage to see if their tyre inflator is any better.

@Goose - would be difficult to say how these IRCs compare to the Schwalbe Ones, as I'm only replacing the rear and they're going on a different bike. The biggest different I think will be the amount they don't cut up.

I seem to recall your rims seal only with the liquid, so I would try to pump them up with the sealant inside and rotate the wheel once you reach the 50 psi mark. You might also need an extra layer of tape, as after a while the existing one flattens a bit

Thanks Ugo, I'll give it a try with the sealant. If I wanted to get the tyre off to add more rim tape, what's the best way to do it given it was tight going on and levers would be needed? Also do you recall what tape was used (width/make)?

The IRC tyre should go on with no levers... more practice needed...

I used 19 mm wide Tesa tape from Ebay, this:

Thanks - the tyre went on without levers, but I won't get it off without using them (to add more tape if needed). They're plastic levers so you reckon I'll be OK if I'm careful?

Yes

Has anyone tried the IRC Formulas (RBCC or light)?
Before I pull the trigger on the roadlite I was wondering if anyone had tried the others from IRC.

If there isn't much difference in durability but feel even better to ride maybe I should give them a try instead. At the end of the day when I manage to drag the bike outside I might as well enjoy it!

I've been wondering exactly the same as I've given up waiting on the the schwables. The roadlite seem to be aimed towards endurance/training where was the formulas are more a race tyre. I will be using them for a combination of training and occasional racing so I don't want anything "sluggish" although some that wears a little better would also be beneficial which is my main concern with the schwalbe pro ones (even if I could find a set!)

I fitted the IRC Roadlite last week, overall they were more time consuming than the Schwalbe but only by a couple of minutes.

One tyre seated with a high volume track pump and the other with co2, both wheels were leaking air which I hadn't experienced with three previous wheels sets with schwalbe (not a huge amount mind you).

When I popped the vale cores out I added about 15ml more sealant than I would normally do, both tyres sealed Ok with only a small amount of sealant leaking externally (I guess I'll have to wait a while before I pull the tyre off to check how it's done internally).

First commute this morning, it was a pretty smooth ride but I need to lower the pressure as they are currently around 95/100 but first impressions are pretty good.

The Roadlite are as fast as any tyre I have used, which includes the Corsa CX tubs. The difference with the Formula is that the roadlite weigh more and as a result they last more and possibly suffer less damage.

For comparison I am now using the Sector, which are even more hard wearing, but they don't feel as good, despite being marginally lighter... I still like them, but they are not special, if you know what I mean... the Roadlite were special

Thanks chaps

If by special you mean the IRC roadlites are like "the special one", I would agree...very difficult to deal with ;-)

I am thinking of getting these for when my tubeless ready wheels turn up... are they difficult to put on ?

drlodge

I've got them on the rim, but not yet able to "pop" the bead onto the rim so its seated. This may be more due to the rim I'm using than the tyre, and/or I need more rim tape. The air is leaking through the dips in the rim tape where the spoke holes are. Just need some free time to try it with sealant in the tyre and plenty of washing up liquid to act as a lubricant.

Sounds like you need another loop of tape. That could make the tyre a little more difficult to get on but should better hold the air as you inflate.

Yep I've ordered a roll of the Tesa 4289 tape that Ugo used, and will gently lever off the tyre to fit some before putting it back on. The tyre was a tight fit, but I think with plenty of lube it will go back on with another layer of tape. I will probably offset this new layer as the rim is asymmetrical and the spoke holes are off to one side.

I am not sure your diagnosis is correct... sometimes the rim-tyre interface is less than perfect for a million reasons, hence the tyre leaks air... you will feel it coming from the holes or the valve, but it's not necessarily where it's coming from. Generally sealant cures the problem. It's more to do with the rim than the tyre, as you correctly point out. Unsurprisingly I find my HED plus rims are the best when it comes to tubeless, as they have not given me any trouble at all in two years and several sets of tyres. The only one that did leak a bit was a Vittoria Voyager (20-30 PSI over night), but it wasn't a tubeless tyre, so hard to say where the fault was.

Time has come through a few cuts and scrapes to invest in some new tyres. I fancy tubeless and was looking at potentially getting some of the roadlites. I have Archetype rims which I gather are technically not tubeless rims but seem to work alright. Any thoughts on the combination? Other than tyres, valves, tape and sealant, is there anything else that I haven’t thought of? Don’t want to waste the money if they will not work with the rims though, someone fill me with confidence that all will be ok please……

Thanks in advance

Should work OK... I've converted Archetype to Schwalbe ONE no problem

oldbazza

Currently running Hutchinson Sectors on Archetypes with no issues.

Great, Thanks Guys, Will give it a try i reckon!

Tape has arrived, just wondering how "much" to put on. It looks like there are at least two layers overlapping a bit. Should I go round the rim once centering over the spoke holes, or twice (overlapping a bit) to more fully cover what is already there ?

ugo.santalucia

try one layer first

gaffer_slow

do archetypes "crack" onto the rim?

has anyone had a tyre seal successfully (spraying like a katherine wheel) as the bead of the tyre stays seated / clamped into the rim minimising loss of pressure?

they don't pop, no... they are not tubeless specific rims

Nope mine didn't as Ugo said,they seemed to ease themselves on after some effort with a track pump.

Sorted! One new layer of tape and some rich washing liquid solution and they popped on instantly air was put in :-) will leave for a bit then add milk.

Thanks, have ordered the roadlites for now from thecycleclinic.
