Any one have experience of Hutchinson Overides?
Is there a difference between these two?

The one on the decathlon website says "This version comes in clincher format with 33 tpi casing making the tyre more affordable tyre."
Sigma: "High-quality 127 tpi casing for a better deflection capacity on roads and paths"
To be honest, I am not sure I 100% trust what's written on the decathlon website. Maybe have a look on the Hutchinson website, see if they do actually make two versions.

Don't have any experience with these, but the decathlon set are not tubeless and have lower tpi so less supple in theory. Was thinking of getting these for my commuter, the non-tubeless one

Closer look on Hutchinson website confirms what Decathlon says, the 33tpi version is wire bead, tube on and 55g heavy for the 700*38 variant.
Sigma version also has 'Hardskin' reinforcement and is folding bead - if I'm interpreting the table correctly.

I quite like them, at least compared to my 32mm (non-tubeless) Gravel Kings that I had on previously. They don't feel slow and they seem to be a lot grippier. Have got less than 40psi in them and they're feeling good. No punctures or visible wear yet but probably only done 100km.
I can't say whether they're better or worse than any other 38mm tubeless tyre though. My flatmate reckons they're less supple than his 38mm GKs but the recommended pressure is lower so that probably evens out.
For around £50 for the pair I'm pretty happy -you might be able to find them cheaper on one of the German websites
@oheyitsdrew there are several versions, if it's non-tubeless it'll be 33tpi

Worth pointing out tpi counts are measured differently by different manufacturers

Thanks very much for the feedback, what makes them preferable to the GK's? - that's another tyre in the pile for consideration.
General tyre question, is there a penalty if one ends up running TLC tyres with tubes?
-
• #7059
Tubeless tires generally have stiffer sidewalls. Add a tube and you get worst of both systems
-
• #7060
So I'd be better off narrowing my search for an all road tyre to ones that aren't tubeless ready?
-
• #7061
I don't think there's that much choice anymore. Most brands do a 2 tier system with a lower quality non tubeless and a more expensive tubeless.
-
• #7062
definilty a penalty at least when it comes to larger tyres, whose upper pressure limit is low. go up to that pressure and beyond and the tyre profile can change, leading to a harsher ride

Used the overides in 35c, non tubeless version from Paris to Torino to Nice over two weeks. A friend had the 38 (not tubeless as well). We wanted something that’d roll nicely on tarmac (1st week) and that could then handle a bit of unpaved fun (Torino Nice Rally). They were fine. No punctures during the first week, four during the second (two snakebites on the mountains, two stationary, come back to a flat wheel after a coffee kind of things).
My pair started getting loads of punctures about a month after we were done.

Kudos for doing TNR on 35c

• #7065
Aha thanks. It had to be that bike and that was the biggest that would fit. It was mostly alright though. Travel light and tread carefully. The absolute worst bit was the Strada Dei Cannoni. But that would have been bad on anything bar a MTB I reckon.

I found the GKs not very grippy and also felt I had quite a few punctures on them. They were the old pre-tubeless version though, maybe the newer versions are better.
-
• #7067
No, they were awful for me with tubes to the extent I'd say incompatible. Also grip wasn't anything special and while it may be related to my rims, a pain to fit. I have tubed G-Ones now, very pleased with them.

Recently bought some Continental 25-32 Race28 W tubes to go with a new set of GP 4000S II tyres (28mm). As someone who's never had any major issues with tube/tyre combos before I've had three blowouts in the last week, one at speed which was pretty sketchy. I imagine the tube must be getting pinched somewhere but once pumped a little and rolled about I can't see any tube protruding. Any one had issues with this combo before? Might switch to Schwalbe tubes...

Panaracer are always a bit snug (rim dependent), gravelkings just need a stretch before they go anywhere near a rim, place foot in tyre, put foot on floor, grab tyre in hand, and pull like fook, repeat working your way round the tyre, approach rim with tyre, and on it goes, no problems.
Tubed, the file tread does puncture easily (check the weight of em, they're fairly light tyres), but I've had no problems with the tlc version. -

So far on my veloflex master (gumwall) i must say i am very impressed with the rolling resistant, but also the puncture resistant. Definetly would recommend them over the corsa g which i had about 2 months before getting rid of them due to their poor performance on the road and track.
My experience with Veloflex also. Crucially they don't seem to get cut to ribbons like Vittoria anytime they come near any broken glass.

Ok, despite warnings over punctures I decided to give GK's a go anyway because they tick most of my boxes. However, I've ordered two sets of clincher non tubeless 700x32c from two different retailers only to receive TLC versions instead. These do just about go onto my rims, but not well enough to make a puncture in the middle of nowhere an attractive proposition.
Does anyone know if non tubeless 700x32c actually exists? It's not listed on Panaracer website so I assumed they don't make it anymore but was hoping these places had stock left over.
If they don't exist where do I go from here for a similar non tubeless tan wall tyre? Or do I forget tan wall and throw 32mm GP5000's on my touring bike for the summer (caution meet wind).

Would leaving them over-inflated a little for a few days stretch them out a bit?

Use a thinner tube :)

Maybe? I can't see them stretching much like that though, as once the bead is over the rim it will happily go back to it's natural size. Plus I don't have a spare set of wheels to test that out on sadly.

I've never used that exact combo, but equally I've never had any issues with Conti inner tubes and GP4000Sii tyres. Sounds like the inner tube might be getting trapped by the bead of the tyre. I've had a few explosive blowouts due to that happening, happily never while I've been riding them. I've definitely had blowouts where the inner tube was trapped between the tyre bead and the rim, even though there was no visible inner tube once it was inflated. One was sufficiently violent I ended up spilling my porridge, despite being in a different room.
What works for me is, after fitting the inner tube and tyre, to push the beads of the tyre back into the bead well in the rim, so that the rim beads are nice and floppy. That'll help ensure that the inner tube isn't trapped between the tyre bead and the rim when you inflate the inner tube. Then inflate away.
Any sites I've checked the skids are no longer available.
