Rene Herse Juniper Ridge Actual Width (44.5mm instead of 48mm)

Does anyone have experience with Rene Herse Juniper Ridge (650 x 48) tires? How wide do they measure?

I just mounted them on my DT Swiss R500 rim which has a 22mm internal width and at 30 psi they're only 44.5mm. I was hoping to replace my Panaracer Gravel King SKs 650 x 48 which at 51.5mm are too wide and don't leave much frame clearance. 7mm difference between two tires spec'd as the same width, the tire industry needs to get their act together!

I've told Jan to hurry up and make these in 2.1", which might end up at 48mm or so

Maybe you can return them?

Width/height measurements are now provided assuming the tire is pumped up to the maximum PSI, while being used tubeless, on rims at least 25mm wide. This coming from the posts about tire width by company representatives for Rene Herse/Compass, that I've seen online the past few years. Something to keep in mind.

I've reached out to Rene Herse for their help.

While I wouldn't normally quibble about a few mm, the reason I went with a 650 was to get 48mm over the 42mm max of the 700cc width.

If you haven't ridden them or put in sealant you can probably return them. If you've used them, they are undoubtedly yours to keep. Seems obvious but may save you some time.

Compass/Rene Herse tires are known (and expected) to measure small when first mounted.

And like Spoonrobot pointed out, they treat the nominal width as a maximum. Jan has defended this in terms of making sure a tire will clear a frame under worst case circumstances. For that matter, are you measuring the width at the casing, or where the knobs stick out at the sides?


P.S. As a data point, my Naches Pass tires are advertised as 44mm, but even after two seasons of riding still measure 42-43mm. If I pumped them up to the maximum, they might reach the full 44mm, but I'm happy that I don't have to, and 42-43mm is plenty.

My Rat Trap Pass tires measure between 57 and 58 mm at 30 psi. This is about 1mm less than advertised. I've had them mounted for about 5 months - with tubes - on 39mm internal width rims.

Rat Trap Pass actually get advertised - sort of - as inflating to around 2.1" in most use cases. The "2.3" labeling is apparently something that Panaracer's engineers opted for because the casing width is the same as Panaracer 2.3" knobby MTB tires, so that their workers wouldn't use the wrong silicon bladder when vulcanizing the tires in the mold.
While it's possible to mount an RTP on something with 39mm internal width, such wide rims are usually targeted at plus or fat use cases; for instance, the Velocity Dually claims to be suitable for tires from 60-80mm in width. I'd imagine that the vast majority of bikes using Rat Trap Pass tires have rims from 17mm to 30mm internal width.

If they mount up to nominal size in your case, this is more coincidence than intention.

Those are great tires, if I had some 650b rims they would be my first choice. Loving the Steilacoom 700c version.

Maybe I’m in the minority, but I don’t think wiser is always necessarily better. Really depends on the terrain and how aggressive a rider you are.

The reason I'm quibbling over a few mm is because I chose a 650 wheelset over 700c for an extra 5mm of width (my frame can do 700 x 42 or 650 .x 47). But if I'm only getting an extra 2.5mm of width, I'm not sure it's worth the additional bottom bracket drop and increase of pedal strikes.

I'm measuring at the casing which is the widest part of these tires.

Seems as if WTB has a couple of 650bX47. Might be worth a try.

haha... just realized my spell changed “wider” to “wiser”!

yeah.. I hear ya. The jury is still out for me on 650B. I definitely can see the benefits of added volume, but is it worth the handling changes?? Especially when your already happy with the handling of 700c. Some folks swear by it though. Need to borrow a set one of these days.

You gonna return those tires or give ‘me a try??

I love the handling of my bike with 700 x 35. I wanted more volume, so I tried 700 x 44, but found the changed steering geometry makes the handling too slow. I then tried 650b x 2.1" Schwalbe ThunderBurt (which has the same outer diameter as 700 x 35) and the steering is more nimble, plus I have huge volume. The tyres are bigger than I need for the trails I am riding, so I've just fitted 650b x 1.95" Maxxis to see if that is a further improvement to the handling/agility while still giving good air volume.
