Best Tire Pressure

Tire pressure is all a matter of comforability and ones opinion. To me, i am most comfortable with 36f-38r. Plus, it all depends on the riding that you do.
 
I made a quick profile view so you can see what kind of contact patch you will get. Now this is generic and tires are made differently but you get the basic idea.

hope it helps

Yeah 32 32 should be perfect for the street and maybe a pound or two less for the track.

Your 200 probably is a little bigger than your gonna need but like you said your not in the AFM and you shouldn't be ricky road racer on the street and having said that like you said it just looks cool. So not to worry. If you start getting serious into track days look at something a little different.

Holy crap 36F 42R cold. Thats high even for a heavy guy. I would feel like I'm riding on ice. I'm only 135 so when I rode my qualifiers at the track I was running as low as 28 28 cold. 35-35 would be about my max on those tires for the street and the track would be maybe 31 31 for the track for you. I haven't rode street in a very long time but qualifiers I don't believe have changed in the past two years but thats the pressures I was running a while back for qualifiers.

Schweet, I'm gonna go adjust my pressures and head out here in a few minutes to test it out

I guess what I'm asking is, it's not going to be BAD, right? I just don't want to have that "oh shit I just spent 200 bux on somthing stupid" feeling.

And in regards to the pressure, 32/32 sounds like what I'm hearing, right?

not stupid

ok

but that also depends on lap times and how the tires looked afterwards

and were they 100% cold? im talking setting the pressure inside your garage after sitting in there all night long (cold). even having your tires sit in the sun on the trailer ride to the track will effect the pressure. it only takes 30 min of a tire sitting in the sun to have a warmer temp by about .5 lbs to 2 lbs

Well again, I had a 190/55 with a screw in it, or a 200/55 right then, installed in an hour, and I was off riding again, I took the option.

Thanks for the advice, I've tried to get an answer for this question a few times, and you know how it is on BARF, a bunch of ADD-tards. HAHA like me.

Ok for real this time, I'm gonn go putt around at 32/32 before it gets dark to see what it feels like.

no your cold pressure effects carcus flex and friction which determins how hot the tire gets and how much rise you get in the tire.

Wish some of the professionals would step in here I am getting ahead of myself.

so if you put in 36 on your rear and it got hot and say we have the +6 here, that is 42 and at the max listed on most tires.

me, i run 32(front) , 32 sport, and 32, 34 sm for the twisties. 36/36 slab touring.

general rule is more pressure cold = less heat put into the tire. so that means you start at higher pressure you get less rise..

It is all greek tome I am just reguritating what I have been told :laughing
 
I don't know about races, but for me, once the tire has a few hundred miles, I run bike manufacturer's specs. Try this on a track/section of highway that you know well: run it at specs, then run it at whatever, and tell me what the bike does.
 
To the OP, I have the same tires on my new 1000RR and I ran this same question past Supertireguy, because I haven't run street tires on a bike in a while. I had originally run 30/30 on them and they felt okay, but STG suggested slightly higher pressures, no lower than 33R/32F on the street. They feel fine at those pressures. The dealer had set them at 37R/36F new and I didn't care for the feel at those pressures.
 
I'm a nub to bike tire pressures. What is the benefit of running higher pressures? I know on the car, you can dial in F/R traction by going higher or lower with the pressures. Not sure how that changes with only 2 wheels on the ground

Higher pressures equals, generally, taller tire, slightly smaller contact patch, and less flex in the tire, which means less heat. Less heat, plus smaller contact patch, means less wear. Downside is smaller contact patch and, generally, less grip, though it depends on the tire, it's optimum heat ranges, etc., etc.

Lower pressures generally means a slightly larger contact patch, more flex in the tire, more heat, grip and wear, slightly slower turn in, yada, yada, yada.

However, you need to remember that different tires, constructions and compounds behave differently at different pressures, so the above is not an absolute at all. It's most applicable if you're talking about a street sport tire like a Qualifier, Power, etc.
