Got some nice tyres....latex or butyl tubes?

I've got some Vittoria corsa SC2 tyres for nice summer days. 320tpi casings so should be nice and soft riding. Do I go for latex tubes or lightweight butyls? I'm going around in circles with this...latex seem to be the best for ride feel but are they as robust as a butyl tube? The issue of them going down isn't so much of a problem as I check my pressures before every ride anyway....
Interested to hear from those who have ridden both. Thanks.

Yeah the tyres are pretty thin to be honest. I wanted some tan walls and these review very well, may end up changing them out for something a bit beefier if they prove problematic...
I've got a pair of Reynolds Assaults with Michelin latex tubes and Vittoria Corsa SCs. There was an article on Velonews which recommended that you avoided mixing carbon wheels and latex tubes due to hear build-up. At the same time, the author (Zinn?) mentioned he had been using latex without a problem...
For sure, I won't be taking them to the mountains but I can't see the heat from local rides/races being an issue.
Nice, but not that much different and have to be pumped up on a daily basis. Not much faff, but unnecessary.
I am not sure. You have no chance.
I have latex in my Assaults and have run them for 12 months without any problems. I don't think heat build up will be a problem in the UK but would definitely be an issue on long alpine descents but I would question the use of carbon clinchers as a wheel choice rather than the tubes in this situation. As others have said just get into the routine of checking pressures before every ride.
There is a significant difference in weight between the two types of tubes which makes them worthwhile in my opinion.
Latex tubes are reliable. They are actually quite ressistant to pinch flats as latex is so much more stretchy than butyl.
The differences quoted in rolling resistance are about the same difference as a good tyre, to a great tyre. So, if you're already buying nice tyres, why not go for it? Some say they can feel it. I would say I can, but no blinded test.
Regarding pressure loss... if you're already taking time to think about which inner tube you want, then you're probably checking tyre pressure before each ride, so no issue.
You occasionally see reports of the tyre or tube exploding when pumped up, which almost certainly only a sign that the person didn't seat the tube properly. Why would the material of the inner tube make a tyre explode??
Sorry, can't really let you get away with that
I will 'fess up, I haven't tried latex but I have ridden on many club rides with folks who are on latex. There seems to be no general consensus on ride feel but that doesn't mean that, for some, they do offer something. For me though, riding some decent tyres like the Vittoria SC's really does make a big difference; they are lovely, lovely tyres to ride, providing the right pressure is used (no point buying lovely supple tyres and pumping them up to 120PSI). However, they are down the scale in terms of puncture protection and are not durable (wear is consistent with a luxury tyre, as in, not great). The other problem is that if you get caught in a heavy downpour then the gum walls will stain badly which I don't mind but others might.
The one downside of latex tubes for me (which is why I haven't tried them) is the fact that when they puncture they really go bang. I have yet to ride with anyone who has punctured on latex who has been left with a tube that could be repaired. Not a problem if you are in a TT or have plenty of tubes, etc., but if you are out on a remote 100 miler and need to rely on tubes/sticky patching to get you home on a bad day at the office then latex do not appear to be the answer.
As per the OP, I don't think the "check pressure before each ride" is an issue, as I do that anyway in the same way I also check brakes, chain, etc.
OP, latex tubes are pretty cheap so well worth a punt. Why not give 'em a go and let us know what you think?
On the downside, you do need to pump them up every time you go out. Many people, however, would do that anyway, even with butyl tubes. They are obviously more delicate than butyl and slightly more fiddly to insert into the tyre, particularly open tubular types, but I use talcum powder and a bit of care and I've never pinch flatted one while fitting. I've had a couple of catastrophic failures such as when I've hit a rock, splitting the sidewall of the tyre and writing off the tube, or when a tube has split near the valve - but then I've had similar failures with butyl. I've also had a couple of old spare latex tubes perish into a myriad of little cracks, so I now carry butyls as spares in my seatpack. I've used them in the Alps with no issues on alloy rims, but I do know that they are not recommended for mountain use with carbon rims because of the overheating risk.
So I think latex are well worth trying as a match for lightweight supple tyres.
You're right, it's not the weight, it's the suppleness. They're only a fraction lighter.
I've been using latex in my best wheels for years and haven't found they puncture any differently to butyl. What I have found is as with Mercia Man they are easier to pinch between the rim and the tyre if you have tight fitting tyres and aren't careful - this may account for the tyres going bang because that is symptomatic of a pinched tube. So long as the tube is fitted properly though they don't puncture any differently to butyl and can be repaired with normal butyl patch kits - that is my experience anyway.
I think it was closer to 30g when I weighed them last :roll: which equates to a 60g saving of about £6 or £7. People pay silly amounts to reduce weight on set of wheels so if you are already running a set of lightweight wheels then removing another 50 or 60 grams from the total weight for such little outlay is a no brainer.
Lightweight butyl like Supersonics are actually lighter though (50g compared to 75g Michelin Latex).
I think it makes sense that if you are spending money on really supple 320tpi tyres, you should try the most supple tubes to get the maximum benefit. On the other hand, if you are on Conti Gatorskins or Schwalbe Marathons, butyl is best.
Surely pressure is more relevant?
I am not sure. You have no chance.
I am wondering is some cheap branded tubes are actually seconds.
I am not sure. You have no chance.
Latex tubes are far more stretchy than butyl - something that can easily be seen by pumping them up outside a tyre. I reckon that this makes them conform to the road surface better than butyl at the same pressure, thereby providing the supple ride quality for which latex is known.
For the full latex effect to be felt, they are best paired with lightweight and supple summer race tyres like the Vittoria Open Corsa rather than more substantial four season tyres like the Open Pave you tried them with briefly. They are great for a best summer bike but I wouldn't use them with carbon clinchers or for touring, commuting or regular all-year riding.
Doesn't say what their fears are based on, if it's just pumping a tube up outside a tyre doesn't seem to mean much, Vittoria claim latex tubes are more puncture resistant than butyl (yes they do sell them but they also sell butyl) so I would go with personal experience.
Never mind as personally I don't want to be using anything less durable on our roads, and the Paves are hardly durable.
I am not sure. You have no chance.
Is this a joke?
Why don't you just try them?
Have never used lightweight butyl, but latex feel/ride great IME.
Just the right amount that they are a bit more comfortable when you need it most
Have never checked after a ride but 10% would be fine by me.
I am not sure. You have no chance.

I found them extremely easy to fit (I put them in a plastic bag first and dumped in some talc to coat them) and i had both wheels done within 5 or 6 minutes.
BTW GP4000's are simple to fold on by hand compared to ultra tight Pro4 SC's!!!
But on a more serious note, I would pump latex up every ride (or maybe not for next day if its a recovery ride 8)).
10psi overnight is a big difference over 3 days.
If thats what you do with butyl anyway then somethings wrong as latex deflates much quicker.
I have just got a Topeak smart head for the track pump.
Hopefully it will be much better than the standard valve head which just blows off the smooth stems you get with latex tubes.
Should also mean that you don't rip the valve from the latex when pushing the head onto a partially inflated (with no lockring) tubes stem.
I have used a variety of tubes including:
- 50 g butyl (Continental Supersonics)
- 75 g butyl (Michelin Aircomp Ultra Light)
- full-fat butyl (~100 g)
- 70 g latex (Michelin Aircomp Latex).
The 100 g butyl tubes of the sort you get on new bicycles tolerate a lot of abuse during fitting (and bad rim tape, rough rim beds, etc.) and hold air for a long time. So much so that you can go a couple of weeks without pumping if you’re not fanatic about tyre pressure. However, a pair of them absorb maybe 3 W more than lighter options, and they feel slightly less supple than latex.Latex tubes feel slightly better and sound a bit different too (as someone already mentioned). According to tests, they reduce rolling resistance by just enough to matter. They are also more resistant to pinch flatting. Installing 70 g latex tubes requires some care but you don’t have to be a mechanical wizard to do it. However, they leak rapidly, so you need to pump them up before every ride.
The 50 g Supersonic butyl tubes are a specialised choice. They have rolling resistance and feel similar to 70 g latex tubes, but they hold air noticeably better. Can be pumped up every few days. However, they are paper thin and ridiculously easy to damage during installation. You have to take extreme measures to ensure the tube is not pinched or twisted before inflating, that the rim tape fits perfectly, that there are no particles of dirt in the tyre, etc. Additionally, the Continental ones (the only 50 g butyl tubes I know of) have threaded valve stems that wreck the rubber washers in traditional pump heads (like my Silca Super Pista).
The 75 g butyl tubes are a halfway house offering a decent advantage in feel and rolling resistance over 100 g butyl, greater durability than 50 g butyl, and less leakage than latex. I think they make sense for many people. The Michelin Aircomp Ultra Light tubes have good valves, too.
I like latex, but having to pump every day is certainly annoying. Maybe it’s okay if you only ride once a week and would check tyre pressures anyway.
