Title: Tire pressure for track day?
Post by: Cam3512 on July 11, 2016, 09:18:10 AM
 Doing my first track day in a couple weeks. It is my understanding that lower tire pressure makes for a better  cornering. What are the recommended pressures  for a closed track, front and rear?

What bike will be used at the track day?

Pressures are a personal deal.  When attending track days with my spine frame bikes, I didn't usually lower the pressures more than a couple pounds from normal solo street settings.

What you for sure don't want to do is start your morning with the pressure at sidewall stated max.  The tires won't warm up quick enough.  I've seen several low-sides at track days because guys were running 36F/42R on their radials.

If this is for your V7, what are you running on the street?  I've been running 35F/35R, and would probably start there if I took mine to a track day.

As Kirby stated above, remember it's not a race.  You're there to learn your machine and yourself, so change as little as possible in your setup, so your experience will translate better back to the street.

 Yes, taking the V7 special. I usually run about 34/36. I'll make sure I stay close to that.

 This is a "street" oriented track day.

 Thanks!

 Gotta agree with Kirby and Mike , the condition of the tires is more important . Leave the pressures close , or even the same as street use .

When I was doing Pridmore's CLASS days he recommended around 32 front and rear. Worked for me. Normally I would be using 36F and 38R on the street.
Check with the guys running the track day when you get there. There should be a compressor there.

Just to pile on and emphasize, this is NOT a race day in any way shape or form, it's a "Street Skills" class being taught ON a safety track.

Since the very essence of what we are learning is for street application, I would say we most certainly would not want to deviate at ALL from our street setup to make sure we're actually practicing skills with a bike that is behaving as it would on the street.

OK, If this is Jon D's deal then street pressures would be what you want. He specifically told me its not high speed.
As for track days not being high speed, thats up to the rider. All the ones I have been to are WFO bouncing the tach off redline.

On what bike and tires, Pete?

32 is a common recommendation for sporty radials, but may not really apply to a V7 with bias tires.

Jason Pridmore recommended the same thing (32/32) as a starting point at his STAR Schools I attended.

This on my '76 Lemans. Sporty bias ply. :grin: Maybe they assumed everyone was running radials. Only one time out of about 20 was my bike not the oldest, thats when a friend brought his '75 R90S.
