help with tyre sizes

Post by smudger2000 »

Hi
Can anyone give me some advice re tyre sizes please
My bike has 26x2.125 (57-559)
I have some spare tyres in my garage one is 26x2.0 (50-559) and the other 26x2.10 (54-559)
Would either of these fit

They all fit a rim with a bead seat diameter of 559 mm, so they should all fit - especially as they are much of a muchness in width - 50 to 57 mm nominally.
