Posted by: Pete TITLE: BALLOON:   single tube tire substitute?
Does anyone know the actual mounted diameter of a single tube tire (28 x 1 1/2")as found on old clad rims from the 20~s or 30~s?
Also what would be a good substitute tire and rim size that would fill fenders properly?
Thanks.

Riding on the bare rims?
Well, that seems a bit extreme.
The bike~s lasted this long, 70 years?
Be a shame to ruin it now.

You probably could until your rim wore out. Before 1900, many bicycle wheels were either steel reinforced wood like a wagon wheel or all steel. But that was when bicycle paths or roadways were dirt and not paved. That~s where the term "boneshaker" came from.

I~ve been looking into this too. There are tubular mountain bike and cyclocross tires in larger sizes in both 700 and 27". Problem is which size. I~ve heard the 700~s fit the narrower track bike rims but have not tried them.

I have used 27 inch 10 speed wheels laced up to a coaster brake hub. 27 x 1 1/4 tires dont look too bad and fill the space in the fender. Fairly cheap too. I dont know anyone that makes a reasonable 28 inch single tube tire. Universals are heavy hollow core rubber and expensive at $120 each. I havent tried Harpers.

Sam,
At my LBS the owner did indeed mount a tubular on my clad rim. Unfortunately it looked a bit like a thong on the fat lady.
What I was originally looking for was the OD or outside diameter of a single tube to see if maybe one of the new style 28 or 29 inch rims and tires might be big and fat enough. Of course they~re really 700C rims with really fat tires. Balloon tires for the new age I guess.
I also looked into airless tires:

They don~t have anything since their tires need a real bead to stay on rim.
So in the end I think I should just bite the bullet and order the right tires.

The old clad wood American rims I~m told are the same size as 700s tubulars.Problem is finding one wide and tall enough.And the price of a wide tubular is 3/4 the price of a single tube.So might as well call Harper and order a set.---sam(in the same boat)

Aren~t those the clincher size 635mm by the new sizing standards? Not that wide though are they?
Something the tire companies ought to include is mounted diameter. I run into this with 700C on modern bikes, the wider it is the taller it is.
I~m kind of stuck betwen laying out the cash for single tube tires or finding a substitute.
If I have to buy new wheels and tires the money might be better spent just buying the right tire.
Going to bike shop today, maybe I~ll take my tape and measure some of those 29-incher tires.

On my wood rim bike, the outside diameter of the tire is 28 inches, the rim diameter is 25 1/2 inches. There were a lot of wheels for 28 inch tires used on British and Canadian bikes, and I have seen some of these being offered on eBay.
