I know this may be an endless debate like oil but I did call American Honda Motorcycle tech support (866) 784-1870 and they say go by the manual which according to them (don't have in front of me) it states "recomended". I called Michelin and they say go by the manual or sticker (if their tires are the same sizes as OEM) which both state the same as the maximum full load on the sidewall. OK, so according to my '05 (says the same for '06) Honda CBR 1000 owners manual (pg 138) it syas 36-F/42-R. I have tired lowering 5lbs and the difference is night and day (it sucks). I know other bikes list different numbers for suggested and maximum as well as autos but this is what Honda is telling us. Unfortunately they have not tested the Michelin's even though they are a MotoGP sponsor and their stickers are on my Repsol. They told me they tested Pirelli, Dunlop and Goodrich and recomend the same tire pressure for those.
Yeah Im confused too, I took it into the shop for some adjustments under warranty and they said my tire pressures seemed low and felt sluggish, but I was running 36 for front and rear. So, they dropped the front to 34 and the rear 42..... I just feel the 42s seem too high. Oh and Im running Corsa III's, but the Honda tech says it doesnt matter. sigh.
On my SV1000S I was told to run them at 28-31front and 32-34rear cold.
I ended up, after playing with geometry, 31Fr & 33 Rr.
Keep in mind the back was a 180/55-17.
Hope this helps.
And before I forget, the guys at SafetyFirst racing (4&6 tuners I believe), we're saying the Power Race tires were folding over at less than 34Fr at BlackHawk Farms and Kansas/Topeka Speedway. They were running 34-36Fr cold...
^ track and street are different and it feels sluggish and heavy with low pressure. I don't think canyon carving will heat up the tires anywhere near a track day or be any different then a long freeway ride.
