See, what sent me off on my tyre-measuring nerd phase was a MBUK review, in which the learned Doddy proclaimed:
“I’ve been running the huge Eskar 2.3s, which… look more like 2.5s.”
So I thought, hmm, I’ve got a set of Eskars, they’re not that big. Measured them and they were just a hair under 2.3! I think everyone knows some tyres are undersized and oversized but to say an accurate one is oversized because it’s bigger than the undersized ones boiled my piss slightly.
An Eskar really does look like an old Maxxis 2.5, say a Highroller, because Maxxis tyres used to all be gigantic fibs. Which I thought was weird because the Highroller 2.6 I had measured 2.5, and the Minion 2.5 I had measured 2.35, and the Minion 2.35 I had measured about 2.15. I never did get to measure a Highroller 2.1 to see if it’s also one size small.
Such things turn normal people into caliper-wielding tyre nerds.
