Can I replace 37-622 tires with 28-622?

[Mick F]

Very old and the tyres say 28 inches?
Same tyres from back then too?

I said earlier that my sister had a bike with 28" tyres in the 1960s. They were bigger than 27" tyres, which are bigger than the modern metric 700c.

I honestly did not expect such quick answers, although I must say I am more confused then I was when I got here. To clarify for some, the bicycle is very old and the 28' notation was used back then a lot and is equivalent of today's 700C. That was never my issue (the diameter) but rather the rim width so that I would know is that 28-622 would fit...

I'm not surprised that you're confused. The early answers were relevant to your question, but then the thread went somewhere else.

Do you follow the recommendations up to the need to discover the width of the rim of your wheel?

Then you can use the table of compatible widths to see if that 28-622 tyre is OK for width.

Yes, I see that's a measurement I can't avoid doing. That mark on the wheel is sure confusing. Sadly, I can't go and take the tire off to measure the wheel right now, but I will be able to get back tomorrow. Thank you for the help.

[Jdsk]

That's what I'd do.

MsMellie - When you measure your rim width, it's more relevant to measure internal as opposed to external width, like this:



Optimum tyre width is 1.8 times the internal rim width, with anywhere between 1.4 and 2.2 times still being ok. There can be a lot more leeway than that, though, before the rim/tyre widths become unsafe, as you'll see from the chart below.

If your wheels came with 37c (37mm) tyres (they're probably a little under that - most tyres are purposely undersize - it's less problematic than oversize), your internal rim width is probably somewhere around 17mm or 19mm or thereabouts. Either would let you fit 28mm tyres, but narrower than 17mm might still be ok:

Hello everybody,

This is a very urgent matter for me, so I appreciate anyone taking the time to read this. .....

ARE YOU STILL THERE? There is a long tradition of people posting once and never being heard from again, particularly when they post on several fora at the same time.

Are there other forums?

Os this the Cof E cyclist forum and I'm a Baptist!!!

No wonder no one's interested in dura ace wheels lol!

Cheers James

I said earlier that my sister had a bike with 28" tyres in the 1960s.

My Auntie Mary had a canary, but thats also unimportant from the point of view of this discussion.

The OP has a bike with 37 x 622 tyres. The question is will their rims which take 37 x 622 tyres also take 28 x 622 tyres and the answer is....MAYBE!
Some rims which fit 37mm tyres are too wide for 28mm tyres, some will be OK.

Just use the ETRTO tyre sizes, forget all the other nonsense written on the tyres and rims.

Agreed x3, although I'm taking your word for it on the canary.

[Mick F]

The OP said his tyre said 28".

Not 27 x 1 1/4 or 26 x 1 3/8 etc.

[tatanab]

The OP said his tyre said 28".

For example, note 622 bead seat diameter.

[Mick F]

Yes, I know what the cardboard label says.
I'm willing to bet that that tyre in the picture from Cordo will say 622.

OP said his TYRE said 28" and that it was an old bike.

In my innocence I thought it was Sister Mary bought a canary to the tune of Catcher in the Rye.

Sister Mary bought a canary
From the butcher's boy.
She hung it up within the dairy
Where it was her joy.
But the bird would never whistle
And she wondered why.
Till she saw the sparrow's feathers
Coming through the dye.

I had two Aunty Marys. .............. or is Maries? What is the plural of Mary?
Or is it that I had two Aunties Mary?

Dad's brother's wife, and the other one was Mum's brother's wife.

Mick also has a parrot.
