I just got my new tires in, and they pulled a switch on me. Not what I ordered.

I want to go to a 700 x 35 road tire, but I'm a bit confused on American equivelants. Is a 27 x 1-1/4 equivelant to a 700 x 35?

Not at all - 27" inch tires and 700 c tires fit entirely different rims. What you can check is the bead seat diameter, which should be impriinted on the sidewall of all bicycle tires. A tire that fits a 700C rim should have a BSD of 622, a 27" tire 630. See https://sheldonbrown.com/tire-sizing.html for full info.

If one was merely looking at width only then 35c is about 1 3/8, and 1 1/4 is about 32c (mm actually

Why not just reject them, and get the supplier to send you what you ordered?

You explained it perfectly. Thanks. I was doing metric conversions, but sites sorta kept lumping the 27's and 700's together, and it seemed like they were suggesting 35 and 1-1/4's were the same. It wasn't making sense.

I don't trust the supplier anymore, because they didn't follow up when they delayed shipping due to inventory issues, then switched tires on me to meet the delivery guarantee with Amazon. It was shady from the start. Beware of BikeWorldUSA.

I decided I'd rather have a 700x35 anyway, instead of the 700x38. Seemed like a good time to change it up.

I've bought from this place, biketiresdirect, and they were OK. Have michelin city tire. they come in 700c by 35.

I've had excellent service from them-
I just live about 70-80 miles down the road, but I've had tires delivered <24hours after ordering them.

Like CNY said: absolutely not. When in doubt, consult the guru: https://sheldonbrown.com/tire-sizing.html

FWIW: Biketiresdirect is a stone's throw from me. However, I've bought a few tires online from Universal: https://www.universalcycles.com/ because they are also local, and I can pick up an order at the counter. They also have shop cats.
