It's a solid starting point to see how things are responding.
Hector,

As Tojo mentioned above, some do still set their pressures cold due to various reasons (not many). Like you, I find it better to set hot off the warmers and then check each time as soon as the bike comes in (adjust if needed). Again, that's just me and others have their reasonsing.

My post was more of clearing the air with someone who didn't read the thread completely and/or was just wanting to argue.

Maybe someone like the OP who doesn't have warmers and wasn't going to be using warmers.

For the OP, they don't really check tires at tech. if they are shagged, they will mention it. They assume racers and riders will swap tires at will over a weekend of riding.

10 years on the track and I have never crashed from a tire losing grip. For the record, I've never crashed on a big bike. Been down on the 250's twice (minis don't count...like crashing on a skateboard) due to being hit once, and a shift fukk-up mid corner due to a recently crashed bike. But never, ever, from a loss of grip. I trust my tires. And the fastest I ever run is 4 - 5% slower than track lap records.

My method is easy.....Set cold in the AM using JOHN HUTCHISON's (SCRC) recommendations, check after one easy session, adjust, check hot off the track 2-3 times throughout the day. They don't change that much and people get pretty worked up about a couple of PSI that doesn't matter one bit until you are 5% off race pace. Some tire vendors won't tell you cold recommendations. That's why I ask John, regardless of what tire it is.

Tire manufacturers have to set a baseline everyone can start with. Take 392's advice and figure it out with the pros in the AM. Get a tire plan together, AND WRITE THAT DOWN on duct tape on your rim or the bike so you won't bug everyone all day long.

Like on my 250 and 500; Rims say: F 27C, 30H. R 26C 28H

Bridgestone says:

BT003 Ride Smart Track Day Tire
(+/- 2 lbs.)
Cold ----------- Off Warmers -------- Hot Off Track
29F / 27R ------ 31F / 29R ----------- 32F / 31R


R10 DOT Race
(+/- 2 lbs.)
Cold ----------- Off Warmers -------- Hot Off Track
26F / 26R ------ 29F / 30R ---------- 31F / 33R

But on my 250 and 500 I can't get 5 pounds of heat in my front r10 cause we can't brake much, so I start a little higher, and the growth is less, so I get closer to recommended PSI....for a 425 pound bike. But since I'm on a 375 pound bike I run with a little less PSI...smoothes out the bumps and has more flex in the sidewall.

Just a little example of what thought process goes into what you do with your tire plan.

I can't imagine an inspector looking to see if a Level one rider has a few cold tears. They are trying to weed out Hyabusas with squared off OEM tires and Ninja 250's with armor all on the tread. Seriously.

Unless you've posted in a public forum and they are looking out for you. Worst case, a good takeoff for $50 will cure the issue.

most of the "race tires" are DOT look alikes and no one would know the difference unless you looked up the compound number and knew exactly what the tread was on it vs the street version it's suttle difference in tread design but MAJOR difference in compounds.

let P1 do your suspesion unless you know what your doing you are just going to end up crashing or messing your bike up big time. not to doubt your abilities or skills but if your still riding LVL 1 trackdays chances are very high you are a track noobie (not putting you down we all started there so no worries or no offense ment by it) and do not have the knowledge to know what 1 click of rebound/ compression or sag would even feel like to know what to change.

ya $30 is well worth a novice who is doing track days to get your bike setup for you. For $30 will it be perfect probably not but will it be good enough for a lvl 2 fast guy yes for sure so lvl 1 your good. as you progress and get faster and faster you'll eat race tires for breakfast and buy more before you go to sleep every night and your wallet will become very thin as you spend money on: race tires, race gas, built suspension, built race motor, tons of seat time, more expensive gear, more expensive women who dig bikes etc..... is it worth it??? YA lol
