Hi all,
tring to make sense of the tyres i need for the mtx....
the old ones are maked front 2.75 x 18 & the rear is 4.1 x 18.
what does this convert to?

110/100/18?

thanks for that....
i cant see a 4.1 rear though, so i presume i just pick the nearest to it?
which is 4.00/4.75 = 110/90?
would i be ok with a 110/100/18? as this seems to be a more common/cheaper size?
cheers,
GAZ

It goes:

Width/Profile

So the first bit is mm, the next as the percentage hight relative to width.

so 4.1 = 110/90 or 100 or whatever
