Thanks, IWWT!



I´ve been wondering about the difference between MT90-16 and 130/90-16. From some manufacturer´s chart these two seem to have almost identical dimensions, so I was thinking MT90 was something special, probably for Harleys and such.



I have an almost spanking new Metzeler ME 77 130/90 on a spare rim, already, but may very well try a MT90, if necessary.



The front tire (3.25 - 19) has load rating 54 (212 kg) and the 130/90 rear has 67 (307 kg). Together they will be good for 519 kg, if ideally distributed.



The bike weighs in @ 220 kg, naked but filled. Me, m´lady, luggage and all will be at least 260 kg. Totally, with some margin, just under 500 kg. But - most of it will no doubt be carried by the rear wheel. Worth thinking about!



Sture

the MT90 and 130 sizing is just a change in the way tire man. designate sizes they are one and the same

I was just thinking that there probably isn't much diff between 18 & 16 inch tires on the cz's once u take into account the cross section of the tires the 16" is alot fatter so the actual heighth is nearly that of the 18... a person would have to set them side by side and check the differance, then u would know the actual gain in overall gearing....hmmmm ... now someone has to figure out how we can get one of the new 250 series tires on a cx!! ...any ideas?????
