help. Tubular or clincher? How to tell?

Is it possible to tell if a tire/wheel is a tubular or clincher just by looking at it? If so, how? Can you tell me if this appears to be a tubular of clincher?

Can't tell from the photo you posted. Post another photo showing the juncture of the tire and the rim. Or just try to take the tire off. If the tire is glued to the rim and the tube is fully enclosed in the tire, tubular. If the tire can be removed with a lever and the tube pops free, clincher.

Unless someone can definitively identify the Araya label as being clincher or tubular, it's impossible to tell from the photo.

If it is a 27" rim or tire, it is a clincher because 27" tubulars don't exist.

The glue oozing out is a giveaway.. + if the valve stem has no threads on it,
for the ring nut.

Araya made both Keirin racers run tubulars , and that is a big business in Japan.

I've got tubes with no threads so lack of them isn't an accurate indicator.

That sure looks like a tubular to me due to the short sidewall of the rim but look at the photo at this link.
This a photo of a tubular on a rim, you will see the black rubber tread, then the tan colored sidewall and a white material. If you see the material backing then it is a tubular. This material is the part of the tubular that is glued to the rim.

Those are tubulars, there is glue in the rim. The easiest and dumbest way to know is try to unhook it from the rim and look at the rim, if you see something you have not seen before is because are tubulars

The easiest and most reliable way is to is to press your thumbnail, a spoon or a tire lever between the tire and rim.

On a clincher the gap between the tire and rim is radial, ie roughly parallel to the braking surface.

On a tubular the gap will be across and the spook will be roughly perpendicular to the braking surface..

Valve stem with no threads, that means noting. There are plenty of tubes for clinchers that are non threaded.

I think an easier way is seeing if the rim has a hook edge.

The difference between clinchers and tubulars is very obvious. If you try to seperate the tire from the rim (referring to the tire) you will see 1 of 2 choices. 1. you will see tire bead seperating from the rim (probably some inner tube as well) 2. notice that the tire is glued/taped to the rim and usually hard to remove. There are several other ways to tell if you have tubulars or clinchers. A seasoned tubular user can tell quite easy. Tubulars are so fun.
