If you would like to use mx-tyres you will find that most of the manufactures only make them in 18" or 19" so a conversion will give you more tyres to choose from.
I use MT21 (17" - high profile) and find them good but if I have had 18" I could get used tyres (of many types) cheap from a mx-shop.
In some countries (Malawi, Kenya,...) they drive mx/enduro but not big bikes and then 18" it's easier to find then 17".
Yes, it's true that mx-drivers start to use 19" (often with a lower profile) but the enduro drivers still stick to 18" and a higher profile.
Most bikes today come with 17", but eg KTM uses 18".
Is it worth it? I don't think so but you might.... :-)
