Just the regular sealant? I'd use 1.5-2 oz. I use 2.5-3oz for my CX tires on wide rims, so definitely less than that.

Any run that doesn't include pooping in someone's front yard is a win.

One of the little red cups worth that come with the bottle should be plenty, without being overnkill.

I've always used half the bottle per road tire (1oz/tube). Easy to eyeball and nothing left over when setting up a pair of wheels. Much more sealant required for, say, tubeless mtb tires.

one of those individual use containers is plenty. I actually reuse that bottle and fill it from my larger container.

fwiw I've NOT had good experience at higher pressures (Road) and Stans. Orange Seal (my all around fave) and effetto mariposa "seem" to work better and (perhaps more importantly) don't create "boogers" - or add glitter to your stans to give it some substance. ymmv

I use Truckerco Sealant I buy off of E-bay... more similar to the Stan's Race Formula vs. Regular Stan's and pretty inexpensive. It comes with an injector too... a syringe with a tube, doesn't have to be fancy.

I use it more in my 29'er honestly.... but when I do put it in my TT bike latex race tubes I use about 1.5oz's.

At least 1 oz. 2 oz is the upper limit for a tire that small.

I agree with others that the plain Stan's doesn't do much except seal pinholes at road pressures. You (likely) won't be able to inject glitter through valve core either. If you haven't dumped it in yet, I would recommend Bontrager TLR, Effeto Mariposa, Orange Seal or Stan's Race instead.

On my race wheels, IE: Tufo Jet Elite 160 tubulars, i inject 1 bottle per wheel. Has saved me in a 70.3 race already.
