It won't be loose once it's seated. Put a tube in to verify this. I've given you three methods to get it inflated, but what's the point of asking for advice if you just carry on regardless.

The tire is way too loose. Period. I didn't ask for advice on how to use it from you or anyone else - why would I when it's unsafe. I asked if anyone else had recent problems, as I was aware of issues some while ago but hadn't seen any recent complaints.

Too loose to inflate, yes, but not too loose to ride safely on a hooked rim once inflated.

When you've mounted lots of different tubeless tyre and rim combinations, you realise that loose tyres are just one of the niggles of tubeless that you need to deal with. It's not necessarily the tyre's fault alone, as it may be fine on another rim or with more tape.

Old tyres that you've removed to fit on another wheel can also be super loose. I've just swapped around some Corsa Pros and Power Cups that were both as baggy as a wizard's sleeve, but rather than curse Vittoria and Michelin, I used the techniques mentioned to get them inflated, and now they're up, they're perfectly fine and stay locked to the rim bead when flat, i.e. totally safe.

In a perfect world, a tubeless tyre will inflate with just a track pump. I find GP5000s are good for this on a lot of rims. In many other cases, you need to lube the rim and bead and use a booster or compessor. In the worst cases, that doesn't work either, and you then need to add more tape or try one of the other tricks to get the tyre to inflate. I've had plenty of loose tyres to deal with, but I've always managed to get them up one way or another.

Anyone tried the Thundero 48? BRR are reporting both tread and sidewall puncture resistance as being significantly stronger than the 40 or 44, or the 40HD. If that's borne out by others' experience, maybe not worth waiting for stock of the 48 HD.

This is less surprising once you look at the weights ... it's miles over spec. 55g over.

I've used the 40mm ones for a while and they're some of the looser tires I've fitted. However it's nothing another later of rim tape didn't solve. They then went up with just a track pump and haven't given any issues since.

I use the 48mm HD version and to me it's faster than the WTB Vulpine 40mm which I found fast to begin with.

Haven't punctured yet so can't tell you how the HD variant is like.

It also doesn't have that firm feeling sidewall like the 40/44mm version which is a benefit for me.

I just ordered a set of Tufo Swampero HD 44mm in Black/Tan for my new gravel build, I am hoping to use them as a fit and forget for all surfaces / seasons (I live in the UK) and seems to me the HD should address some of the reported issues with puncture resistance.
I had wanted the Thundero HD, as they are probably a little faster in dry conditions, but not in stock anywhere apart from Tufo and didn't want to splash €200 (4 x tyres) to qualify for free shipping to UK, and the Swampero should be the better bet when things get wet/muddy here.
Once I have the new rig built up and I have been out on a few shake down rides I will report back, and they will get a good test at the 215km gravel event I have at the end of June, as will I, as I am currently not fit.

Given recent form, it's difficult to imagine a Hutchinson tire that doesn't have terrible RR.

Agreed. I hope they make a fast tire, but I doubt it. This tire reminds me a lot of the Vittoria Terreno Zero, only with slightly larger shoulder tread. While I liked that tire, it is for sure on the slower side (despite being almost smooth tread) and the lack of shoulder tread put me on the ground around a loose corner.

To my eyes it looks more like a Pathfinder. I can't say I'm a fan of these tyres with the slick centre tread and tread on the side, cornering on the tarmac can be a little sketchey at times.

Just received my Tufo Swampero HD 44mm in Tan wall, they are a fair bit over the 480g spec weight, as mine weigh 537g on my scales. I am not that fussed as 110g or so extra weight in the scheme of things is minor as I weigh 85kg, and I can (should!) lose around 5-8kg to be a bit nearer race weight.

One thing that I did notice is that the tread depth / tyre knobs are not as aggressive (high) as the pictures indicate, certainly down the middle section of the tyre, which for me is a good thing as they look like an even better all rounder tread pattern in the flesh. The tread also feels quite soft, grippy rubber, so all in all looking forward to getting them on the new bike.

Once my new rig is built and I can get some serious training KM's/miles in before my event in June, I will report back, as it wil be good to compare to the Pirelli Cinturato M (40mm) I have been using, and the 43mm Gravelkings I used previously.

I would post some images that are saved on my phone/PC, I am sure it used to be easy, but now seems difficult to find/see how to do so or you need to use an image hosting site, which seems a bit of a faff.

Based on BRR voting numbers it looks like their hot new road tire should get voted through this month, which means by the end of June we'll have some data on the best compund and casing technology they're currently capable of even if it's not a test of the gravel tire itself. Maybe I'll be interested in throwing my vote behind the gravel offering once I see the road results, but based on everything else Hutchison have released in the last few years my expectations aren't high.

I'd be really intereted to hear about them. I'm considering them for my commuter bike which does a fair bit of gravel as they'd basically be fit and forget tyres suitable nearly all year round.

Looking to buy them when my current tyres wear out which given they're Terra Speeds will be in a week or two :lol:

Looking at this way too closely-
I wouldn't run out and buy one, but Hutch made Pirelli's gravel tires for a bit (Pirelli has moved on, but the BRR tests are Hutchinson/France made tires).

The current Hutch tires have too much casing and maybe a slow rubber.
This is about the same casing (structure wise) as the Pirelli gravel H, while the prior ones ("Hardskin") were close to the reinforced "-X" Pirellis - about 1.5watts on BRR.
Looking at at the marketing they traded some rubber grip for rolling resistance. Hutch's rubber was about 25% more grippy than most of the faster rolling tires (harder compounds do better on the BRR test). The 11storm road rubber is about 2w slower than Contis GP5k rubber, and this says is 'better'.

Anyway, I predict this would roll like a Pirelli gravel H or slightly better. This might be a good mostly road, converted railroad trail, travel tire.
