700x45 Tubeless for Pavement ?
 
Looking for new 700x45 tubeless for riding on pavement only .
Not looking for gravel grinder .
I want this specific size .
Thanks .

As a last resort , will consider non-tubeless supple tire with puncture protection , if that exists .

Rene Herse Snoqualmie Pass is listed 700x44, although they supposedly tend to run 1 or 2 mm narrow. Soma Supple Vitesse is available tubeless in 700x48.

I can understand needing to not go larger than 45, since its often a frame fit issue. But you snagged me in- super curious why you 'really need' 45s specifically? Two tires totally identical except for being 43mm and 45mm just isnt a difference I could see mattering.

Can't go larger than 45 .
Your right , 43/45 no real dfif , but e-bike mileage sensor is sensitive to tire size .

The size imprinted on the side of a tire does not mean that every tire of that size will have the same outside circumference which is what your mileage sensor is estimating. Basing tire choice without an actual physical measurement of the circumference of the tire in question makes no sense. Most bike computers are programmable, is yours not?

Good points , I'll check .

Think how much wrong it could possibly be - about 0.2% per mm - and then decide not to worry.

Maybe someday someone will invent a speed sensor that shoots a laser at the ground like computer mice do.

I have been using the "rollout" method to calibrate my speedos, it has been super accurate when compared to GPS.

WTB Riddler (45mm), WTB Byway (44mm), Panaracer Gravelking SK (43mm).

Any tire will be wider on wider rims. Tubeless will run wider than tubed. Tires with same width will have different height. Rolling circumference will vary with load and with tire pressure. If the tire does not noticeably sag when loaded pressure is too high. The whole point of wide tires is to utilize the speed and comfort a bit of sag gives.
