Highlander · Post by **Highlander** » Tue May 17, 2005 12:36 pm

hi im lookijng to get Pirrelli Dragon Supercorsa Pro Race tyres for me bike, but my current tyre sizes are -

120/60ZR/17TL
160/60ZR/17TL

However I cant seem to find anybody that does the front tyre at that size...they all appear to be 120/70ZR/17TL... would this fit. if i remeber correctly the first par 120 is like the rim size like 17inches etc. is the 60ZR the diammetter of the tyre, ?? thanks

120mm = width of the rim

60mm = the height of the tyre from the rim

17inch = is the rim diameter

Why they put all of that in metric and then the diameter in inches i dont know

a quick search on google turned this up...

http://www.universal-tyres.co.uk/motorcycle.htm

but they don't do the 160 rear? .....TBH I don't really think a 400 would benefit from such a tyre- when you've only got 60 brake to lay down a tyre like that isn't really necessary

I've heard a lot of the racers say they switch to the 120/70-17 front tyre cause it gives a faster turn-in.

Whether you'd feel much difference on the road is another matter...

As far as i know it will fit fine without scraping the front mudguard or anything daft!

so very very wrong im afraid. check on MCN!

120 is width in mm, 60 is in fact 60% of 120mm thats is the profile and 17 is inch wheel. sori the middle number is a percentage . check in this wenesday mcn for proof or at mcn.co.uk
