27 x 1 Tires

I've got a '84 Shogun 600 with ruddy tires. They aren't horrible on the road, but I recently tried setting the bike up on a resistance trainer, and the uneven rubber gives nasty vibration on the machine.

There are two rims:
- Araya 27 x 1; the tire says "27 x 1 to fit rim 27 x 1 1/2"
- Araya 27 1W

Both existing tires are actually about .8" rather than 1". (Is this something like lumber where a 2x4 isn't literally 2"x4"?)

I can't seem to find "27 x 1" tires online - and definitely not for a trainer tire. Is there possibly a modern size that would work?

Thanks!

Rim width, in general, won't limit your tire width. 27 x 1 1/4 or 27 x 1 1/8 will be fine if you have room under the fork crown, under the rear brake bridge, and between the chainstays. I recommend Panaracer Pasela Protites. Get Folding tires because.

The Panaracer comes in a 27x1 if you want to keep a similar tire width as you have now. Im running them on one of my bikes and really like them

there are several companies that are bad about misrepresenting size. i like to pick on continental, particularly. i bought some 700x38c tour rides once, they were more 32mm in width, though. called the company and they insisted they were correct on sizing

i think it was sheldon brown that wrote about the very issue. so, yeah...tires frequently don't measure true in sizing. otoh, there also many that do. WTB is good about it, ime

You might want to hop on this deal if you want some 27x1" Paselas. There aren't a lot online in that size that I could find easily. It's a pair for $65 shipped and include two schrader valve tubes.

27x1 Paselas are nice on the road but not very easy to find lately (27x1 1/8) Urban Max are good too, but I don't know how nice either would be for training, probably OK.

Protites (especially folding 27x1 1/8) are nice on the road too - but maybe too nice for training - you might wear them quickly depending on how rough your trainer is on tires.

You might want to get a cheap pair of 700c wheels for training, then you could get dedicated training tires. Or you could use 27x1.25 Gatorskins on you current wheels - trainers can be hard on tires (at least my rollers are - don't know what you're using) - FWIW - I've always found Continentals to be larger than advertised. In 27 you could also use Super Sports (tough but heavy dogs) - or Ultra Sports (less tough). Some people love to hate Gatorskins, but in 27", in my opinion, they are often the best choice.

Sheldon Brown's advice on rim vs. tire width: https://www.sheldonbrown.com/tire-sizing.html
"Which tire fits safely on which rim? ...Although you can use practically any tire/rim combination that shares the same bead-seat diameter, as already noted, it is unwise to use widely disparate sizes.

If you use a very narrow tire on a wide rim, you risk pinch flats and rim damage from road hazards.

If you use a very wide tire on a narrow rim, you risk sidewall or rim failure. This combination causes very sloppy handling at low speeds. Unfortunately, current mountain-bike fashion pushes the edge of this. In the interest of weight saving, most current mountain bikes have excessively narrow rims. Such narrow rims work very poorly with wide tires, unless the tires are overinflated...but that defeats the purpose of wide tires, and puts undue stress on the rim sidewalls."

He recommends a tire width approximately 1.4 to 2 times the inner width of the rim.
