I used a set for about 6 months and averaged about a flat per week on my daily commute until I wised up and replaced them with some Schwalbes. The tires I used ( I can't remember which model) were very light and supple. I felt like I was riding on clouds. But with no puncture protection, it wasn't worth it.

Ah thanks for that niknak to good to be true so, just thought i found the perfect tire.

IMHO, the best compromise between durability and cushiness is the Pasela Tour Guard. Halfway between the Schwalbes and Grand Bois in that regard. They're essentially Grand Bois with a kevlar belt. Good value for your money too...

I have some of the Gran Bois in 700x28c and 700x30c. They are certainly more delicate than some of the other tires available, but they are nice and fast. I had a flat the first time I rode them. I put them away for 6 or 8 mo. And since I have been riding them I haven’t had any more flats. I think they hardened up a bit with age. For comfort, I wimp out and favor Vittoria Randonneur Hyper 700x37c, but they also come in 32 and 35c for those who want something smaller. Recently I have been using Conti Gatorskins in 700x28c and 700x32c for a faster tire that still has puncture protection.

At my weight, I wouldn't think of using the Gran Bois for touring, any more than I would tour on sewups. They are too small in cross section and too delicate for me.

They are essentially a sewup with a wire bead. Nice and fast, but a bit delicate.

Light supple and such are a choice for the endurance Brevet riders ,
like those going, fast as they are able, Paris to Brest and Back to Paris.

for Touring I opt for puncture resistance and slow down and enjoy the scenery.

If you plan to tour with a load and use these tires, I hope you are quite a bit lighter than me. At my weight they are fine for unloaded, fast rides, but I feel they are too delicate for loaded touring, but you may differ.

Vittoria Randonneur Hypers are fantastic tires -- fast rolling, durable, folding, flat resistant, reasonably light weight and have reflective sidewalls. Available in a range of widths. I have 700 x 32s on my touring bike and they ride really nice, way better than Pasela TGs IMHO.

I wore out a Grand Bois Hetre this season. I had two flats. No more than I have with any other tire.

hmmm...well it's a randonneuring bike. You could tour on it. You could do group rides, but not race.

I'm not sure how it matters...I know lots of heavy guys on 23s, they don't get any more flats due to the tire's contstruction than anybody else. More pinch flats of course, but that's an issue of volume. There's nothing special about 'touring' as it relates to tires, so far as I can see.

well if i were to use them on my loaded touring bike they would be carrying a lot of weight but then again there are the touring tire of grandbios so should be well capable .
they reckon there as good as tubs which i rode for years, but the tubs are not great either for puncture protection .but i'm a firm beliver than punctures are down to just bad luck get one and you end up getting a dozen for no apparent reason.

I use them for both, road and touring. I weigh 160 and my loaded touring bike weighs 75 lbs.

For my road bike I use the 700x32 (Cypres). My touring bike has the 559x44 (26x1.75")

I've been averaging about 1 flat per 500 miles. Are they worth it? That depends on your riding style, road conditions, and your tolerance to the occasional flat. For me the slight decrease in rolling resistance is, for now, worth the trade off.

A lot of good advice has been given above. Tires, like everything else, are a personal choice.

1 flat per 500 miles is good going i'm thinking. my riding style is no different than anyone else's i reckon most of the time on tarmac seldom off road average speed loaded touring 12mph.
so giving that would you say there better than any of the other tires you have used.i would settle for a flat every 500 miles

I found the Vittoria Rando Hypers very easy to mount. I always use tire tools, if that makes a difference. In contrast, Continental Gatorskins were the hardest tire to mount that I have ever used, even with tire tools. I ultimately had to get my bike shop to mount them, which I had never done before. Maybe I just got a set with an extra thick bead.

My wife uses the Grand Bois Hetres in 650b on her Bleriot. Very prone to flatting until I put some SpinSkins liners in. No flats since and she still loves the way they ride.
