Will these tyres fit?

Ax

I've gone and got myself all confused with tyre sizes!
My current tyres are 37-622 but need replacing. I have a spare pair of 35-622. Can I safely replace the 37-622s with the 35-622s or will I have to buy some new ones?
FYI there are no size markings on the actual wheels but it's a 2005 Dawes Galaxy if that helps.
Any help greatly appreciated, thanks.

They'll be fine, just 2mm narrower widthwise.

Thanks very much for that - Seems obvious now!
I think I got confused by looking at the 28 x 1 3/8 x 1 5/8 type measurements which appeared totally different for each tyre (One was a fraction the other decimal).
I'm guessing I should be a bit faster on a narrower tyre? Although I think it's heavier so maybe not!

2mm wont make much difference.

Actually, I'd have thought not but looking at some 25mm tyres Vs 23mm tyres the 25mm seems well chunky to me compared to some 23's :shock:
