i have seen many discussion on this, so lets see what collective wisdom (if there is such thing) will tell us ;))

36 front 42 rear all year round. I heard that low pressure is one of the causes of cupping.
I run 36 (F) 40 (R) for daily commuting.All weather.
I run 32 (F) 36 (R) for canyon play riding. All weather.
By the book, cause I don't know anything else yet. Once I get a few more miles racked up and the stock tires to the landfill, I'll experiment with the pressures. Does anyone here use nitrogen in their tires?
36 frt / 40 rear

It likes 40psi.I used to check it and put it to 42 and a few days later(no matter the season)it would be back to 40 and then stay there till I pumped it back to 42 ,few days later repete now I just leave it at 40.

Wierd but it only drops pressure if I put it at 42.It has been this way with at least the last two rear tires.
About 32-35 at 70F, and then just let it fluctuate with temperature.

i.e.
28-31 at 30F
34-37 at 90F
33 front, 37 rear

I like odd numbers better.
f36 r42 cold. If it rains then lower them by ~3lbs and go slower.

I've been sneaking over to your house and letting the air out. :balloon:

I usually run the max pressures (36/42), especially when touring. I will sometimes drop both 2 to 4 psi if I'm just backroading it.
This time I'm sticking to 36-42. I weigh 240 and took advise on lowering before to get a better ride with more grip and cupped the front bad. Next time you take off a cupped tire, try pushing on the tread after you remove the tire! It'll scare the crap out of you as to how thin it is.
36 rear 32 front
38r / 34f most of the time. If I'm planning some aggressive twisties I'll drop it to 36r / 32f. Seems to work pretty well carrying my 220 lb ass.

Whenever I drop it lower than that it starts feeling too squirrely for my taste when pushing it.
In the vicinity of 32f/36r (on Pilot Roads). I'll bump it up a couple of pounds for freeway runs.

When I take her to the track, I'll likely go down to 30/30 (and probably try mounting some Pilot Powers or Metzler Z6s).
"Does anyone here use nitrogen in their tires?"
we all use nitrogen in our tires. it's the majority of air.

9 psi rear, 30-38 front. hey! make yours a hardtail and keep it at 32psi...i ain't !

4400 miles on the oem michelin front. sure it's cupped, and sure it's such a hard compound that i sometimes push/skid my front end while trying to do my burnout...but a new one won't make me any quicker so it STAYS.

WOW .. NINE PSI ?? you are not kidding ? what kind of gas millage are you getting ? or is it for a dragstrip exclusively ??
Hello!! I don't need just the pressures! WHAT TIRES ARE YOU USING WITH THESE PRESSURES????
---- Something like this ----------------
I've stated this quite often -- the Pilot Roads love low pressures. Solo pressures rear 31 to 33, front 26 to 29.
Yeah I'm crazy, but this isn't evidence of it. They work brilliantly under all conditions, especially in the wet, and last a good long time. At placard pressures they are a disaster.
This applies to the Roads only!!!!!!!
------ There now, that wasn't so hard was it? -------

Bucky's one of them "straight-liners" so gas mileage is :poop:

But out of curiosity - How many passes would you say you get out of a tank, Bucky? Of course, you probably don't fill it up do ya?

Thanks for the input on the Pilot Roads, Rob. I'll try running mine a bit lower than the pressures I've been running (32f/36r), especially since I'm relatively light (160 lbs.) I've been very pleased with their wet-conditions reliability.
shinko 003, the harder of the two compounds. what was i thinking NOT going with the ultrasoft?

exclusively drag. i think i did less than 1 mile of street riding last year.

i've never tried to calculate my racing mileage. my used PCIII that i bought off ebay a couple of years ago appears to be a big reason why my bike can be VERY fussy starting. i believe that my hard starting almost perfectly coincides with that PCIII installation. so i've been letting my bike idle WAY too much between rounds, to avoid having to rush to the line, use ether, etc. naturally, all the idling will make it tough to calculate mileage. and i'm thinking this wouldn't be an option at race tracks with an air temperature over 70 or so. but i am curious what my actual w.o.t. racing fuel mileage is. no, i avoid filling the tank pretty religiously. okay, agnostically.
