Here in PNG we're all metric.
But I still pump my tires to 30psi
I am 5'11" tall, (not 180cm's)
but I am 100kg's not (i think) 220lbs
I tigten my nuts in foot lb
I ride in kilometers per Hour (regularly above 160)
160klm per hour is still the magic tun!
& my Duc manual is all in Bar, Newton Meters & Milimeters
Boy am I confused!!!
Hey that's a great trick about the +/- 10%, must check it out.
I ride with a couple of Harley boys, 2003 V-Rod & 2003 Electraglide Ultra, (only cause i have to) & it seems there is a lot of variance in Tire pressure.
The Duc agent in Australia told me 30/30, & that's what i run in Metzler 170/70x17 & 120/70x17.
The v-rod has a 180/55x18 on the rear & I think a 120/70x18 on the front & the reccommended tire pressure from Harley is 36 front & 38 rear.
After a long run up the hyway the rear tyre on the Harley is noticably hotter than mine, is their some relationship between Pressure & Temperature in Tyres?
And if so wouldn't it be better to run the higher pressures to get hotter stickier tyres?
