Tire dithering: My Turbos are toast. I have some lightly used Vittoria new hotness and some unused Open Corsas. Am I in for more thin-tire commuting grief if I use them? Should I just buy GP4Ks? I have some Schwalbe Ones to tubeless but my dynamo front wheel isn't tubeless so I've been holding them, should I just tubeless the rear?

Also: actual lols about the new & improved Jan/new & improved tire meta

These are vastly improved.

But yeah. Or the regular Grand Prix as a good compromise.

except for the 42mm WTB those are all teeerrrrible choices for Mig

all will be the same ~53mm size as every other XC MTB tire labeled 2.1" or 2.25"

My business partner switched from the BG to the Compass. Almost identical width, with the Compass a tad under its claimed width. He's on wide rims, but I forget which model on that spencer.

ShartQ: I've been googling actual tyre sizes a bit lately and keep coming up with results from www.bicyclerollingresistance.com
As far as actual tyres size measurements go i don't think it could be toooo controversial but his results seem to fly in the face of the accepted wisdom (and more importantly the Tarck LLC database) when it comes to real world speed/rolling resistance. i.e. the supposedly fast rolling Schwalbe Kojak is apparently crap and SB8's are teh worst?
Should i place any importance on his rolling resistance numbers or are they largely irrelevant in the real world (esp for gravel/off road?)

note i don't have a specific tyre/application in mind just curious

I reckon it's interesting, but probably wouldn't correlate to real world use but is at least comparing apples with apples in a repeatable experiment. His stuff is interesting in comparison to Heiney's "real world" blind rolling tests which give predictably favourable results to his fave tyres.

he is absolutely correct

the Kojak is dramatically slower and harsher IRL than the Marathon Racer (and a few other nicer Marathons that don't have a cm of blue foam under the tread)

the SB8 is also a piece of shit compared to almost any XC WC MTB tire regardless of treadway or protectionway

Heiney has a stick up his ass about how testing on rollers favors the wrong inflation pressures, and can't get over it

but that guy's rankings definitely model real-world speed and comfort at real-world pressures

This is completely anecdotal: Byways roll faster than Horizons. Hell yes.

This is factual: Byways measure out to 44 on an i23 KOM. What the fuck?

They performed beyond expectations today on tough 85 mile ride with pavement and a wide range of different off-road surfaces. 10/10 will schralp again.

This is approximate: Byways and Hetres didn't seem to have a gigantic size difference, as judged my my eye. The byways were obviously wider, but not as much as I expected. Does this mean the hetres are wider, or that the byways are narrower? I'll have to get the calipers out.

I can get you factual numbers for byways on an i25 KOM once I dig out the calipers.

Someone, can't remember who, reported that the newer horizons as well are several mm narrower than labeled. The 1st gen, which I have, seem to be sized exactly

That was me. My first-generation Horizons were 47mm, my second generations seemed significantly heavier and measure 44mm.

Due to concerns about thunder butts not fitting on my La Cruz, I ordered a pair of Panaracer ne Pacenti Quasi-Motos. Two questions. 1) have I made a huge mistake? 2) they're nominally not tubeless. Is it even worth trying to set them up as such?

No, Quasi is not a bad tire. Before Compass 48s I used them cause they were so fast + voluminous.
BITD Pacenti was the only 650b trail tire, tons of folks did them TL. I would keep the pressure ≤30psi.

Five-foot drops at speed on unstable terrain? Yep.

Awesome, good to hear they don't suck. Definitely keeping pressures on the low-end of things if I can get them to set up.

My 42s are 355g each.

they're almost identically sized to the Thunder Burts

but not having full corner knobs means the Quasis will clear stays/fenders a little easier

Cool, I'm tight on clearance with SBHs so I was nervous about the side-knobs on thunderbutts. This pic has Quasimotos mounted to the same frame I have, so I _should_ be alright. My frame's beat to shit as it is, so a little tire rub won't kill it (I hope).

FWIW I ran both the Quasi Motos and Thunder Butts on my Orange Elephant with fairly tight clearances:

I vaguely remember the ThunderBurts being slightly narrower than the QuasiMotos but I might have been comparing stretched out QuasiMotos to brand new ThunderBurts

They were probably confusing the gravel king with the pari moto, which is easy given that they look like the same tire, although the gravel king is supposed to be tubeless and has that awful breaker, which makes it 340 g or so whereas the pari moto is 300g
