BT 003 RS Pressures

08ninja250 · June 4th, 2011, 09:42 PM

Hey Guys,

Im running a 110 front and a 150 rear on my race 250. What pressures are recommended for a hot tire?

V2Neal · June 4th, 2011, 10:06 PM

Pretty sure Stick told me 28/28 hot off the track.

08ninja250 · June 4th, 2011, 10:10 PM

Ok thats what I thought and what Ive been running

Thanks!

Yeah I've been running between 26-28psi in the rear tire depending on the track & temp. Found that dropping the pressure helps a bit when the track is bumpy or slippery but the higher pressure makes it a little more predictable.

ztrack157 · June 5th, 2011, 10:49 AM

I set 25 and 25 cold and leave it

08ninja250 · June 5th, 2011, 12:27 PM

Rexbo, is that hot or cold?

hot... measured either on the warmers (before they got stolen) or right after comin off a session.

Funny thing is, with my pirelli front tire, it works best at like 23-24 psi hot, guess they're all a little different

ztrack157 · June 5th, 2011, 07:49 PM

Steven that lower than the pirelli recommended pressure of 31 hot I run 29 hot with the pirelli which is what my champ runs what works for him must work for me. I will note that you probably don't push the tires to the limit as hard as him or Bartlow does those tires are uber sticky

Maybe... I started out at the 30psi but the front tire would keep chattering at chuckwalla, so I gradually aired it down and it just kept feeling better and better. It didn't feel nearly as planted at buttonwillow though, so maybe airing it back up would have helped there.

ztrack157 · June 5th, 2011, 09:05 PM

That chatter is suspension related not the tires. We will get it fixed when your up here next month.

ratlab · June 13th, 2011, 12:27 AM

25-25 cold for bt-003rs -that's only 3 degrees hotter coming off the track-on my 1000 i run 19-30 cold -dunlops- i am clueless about this little bike stuff-this forum is great

JS73 · June 15th, 2011, 08:42 AM

Yep, 28/28 hot off the warmers.

sowega · June 15th, 2011, 03:47 PM

26.5 on both, fresh off the warmers.

SPG · June 20th, 2011, 03:41 PM

Holy crap! I have been running mine around 28/29 cold or 34/34 off the warmers. I had no idea I could run them that low.

Are you guys running the 28 or 26 hot pressures experiencing any negative side effects? I like stable and predictable (who doesn't in a tire), but my stable predictable bike just chattered it's front tire off of the track last weekend and I'm looking for ways to avoid it in the future.

Running 110/140 for what it's worth and the tires have about 12 track/race days on them.

Could be the fact you got a lot of track days on them, could be that you're running psi too high, or your front springs are too soft (bottoming) or too stiff (not enough travel), then maybe its the bridgestones (I don't like them) and possibly your rear shock is too soft. Lots of options

Bridgestone rep down here in Texas recommends 29f/26r hot.
