Can I replace 37-622 tires with 28-622?
Can I replace 37-622 tires with 28-622?
Hello everybody,
This is a very urgent matter for me, so I appreciate anyone taking the time to read this. I have an older road bike which needs a tire change. On the current tires the markings are 28 x 1 5/8 x 1 3/8 (37-622). Imprinted in the wheel itself is 28 x 1 5/8. My question is, can these tires be replaced by 28-622 tires? Would there be any issues? Thank you in advance!

Welcome.
28-622 is narrower than 37-622:

The ride characteristics and grip might change. What surfaces will you ride on?
But the first thing to check is whether the new tyres are OK for your wheel rims. The linked article above includes a table titled "Which tire fits safely on which rim?".

Welcome to the forum.
The information you have given isn't enough to tell. It depends upon your rim size. And Jdsk beat me to it

Hi and welcome
Most likely, yes they will. As you have been advised above, to make certain you'd want to know what your rim internal width is as well. The Sheldon Brown table is a little conservative, I'd expect a 21mm width rim or narrower to take a 28mm tyre ok

Sorry, you've lost me with the figures.
28 x (anything) is a 28" wheel.
My sister had a bike in the 1960s with 28" wheels.
The "racing bikes" had 27" wheels, and I had that size right into the 1980s.
These days, we have 700c and they are 622 x (whatever width).
27" were 630 .............. and goodness knows what 28" ones were.

28" is used as a synonym for 700c......particularly by German manufacturers, eg schwalbe.Mick F wrote: ↑7 Sep 2021, 4:46pm Sorry, you've lost me with the figures.

Re: Can I replace 37-622 tires with 28-622?
28" is a term still used by many northern Europeans (especially Germans) for 700C (ETRTO 622) wheels and tyres. I have no idea why they insist on using an imperial measurement, but they do.Mick F wrote: ↑7 Sep 2021, 4:46pm Sorry, you've lost me with the figures.

Here for instance is a Schwalbe inner tube designed primarily for 700C (622) tyres. Note what number appears most prominently.
Re: Can I replace 37-622 tires with 28-622?
The OP did say it was an 'older' bike. If it's *really* old, there's a possibility that it is 635, instead, but that seems unlikely from the dimensions given.

I'd be cautious as the rims are 1 5/8"???MsMellie wrote: ↑7 Sep 2021, 3:12pm Hello everybody,

So a 28mm tyre is nominally 1 1/8" so the Rim is half an inch wider than the tyre width. Better going for 35mm tbh.

Re: Can I replace 37-622 tires with 28-622?
I doubt the rims actually measure 1 5/8" (42mm, or thereabouts)
Apart from anything else, a 37mm tyre won't fit a 42mm rim

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.

Re: Can I replace 37-622 tires with 28-622?
The OP ......... should he return .......... said that his tyres were marked 28".
Just to put the record straight regarding 700c.
Yes, no doubt the tubes by Schwalbe etc mention 28" on the box. No doubt the tube will fit 28", 27" and 700c and perhaps 26".
The tyres on my bike are labeled 700c x 23mm.
They also say 622 x 23.
No mention of 28, 27, or even 26.
The rolling diameter of a 700 x 23 .......... 622 x 23 .......... is 26.2".
Fact.

Re: Can I replace 37-622 tires with 28-622?
I am, apologies, but I had to go offline due to real life stuff. 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...

And the sooner we switch to using ISO sizing the sooner we'll have to stop puzzling over markings, looking up what the other person meant, and converting,
