OK, I have to ask because all these different tire pressure figures being used are not helping one little bit with the Whys! & Whats! to do.
The factory pressure is 34F/42R. This is what I've been using because Triumph recommend it for their bike.
Corners runs a whopping 10psi less on the rear and 2 less on the front. G3 also runs these pressures when on Sunday rides, but drops another 6 psi on the rear and another 2 on the front when on the track.
So to help can you answer these questions - PLEASE
Are you running these reduced psi when going through the twisties and on the track because you will be generating more heat and want to compensate for this by running lower pressure or does having a lower pressure give you a better contact patch when lent over in the corners?
What's the difference with the handling characteristics of the bike with the lower pressures to the standard pressures - are you less likely to go wide with the lower pressure?
Does more pressure give the tires a longer life but less performance if you push it through the corners?
I've never given tire pressure much thought before (other than sticking to the factory settings) so your help is appreciated.

Higher pressures do give you more life. It also depends on how you ride. The pressures given by Triumph are for maximum wear but ***** feel and decent grip. Tires are part of the suspension equation. Your feel of the road will change at different pressures... I have picked the combo I use for everyday riding for wear and feel. I find the front finds every nook and cranny at lower pressures when there is not much heat generated. I lke the feel of the rear as it's not too harsh.
The other pressures have to do with heat and contact patch. For Sunday rides, the overall stress on the tires is not as great as on the track, so to get good grip AND decent wear you find the middle ground...
On the track, all bets are off. It's all about how well you stick... Thus the lower pressures to fully maximize heat and stick as well as contact patch. The other side of this is generating too much heat and making the tires TOO soft, thus slick. It depends on the tire really on how far you can push this envelope. Some tires do better at higher pressures, others at lower.
The pilots are great tires but I didn't like the tall profile of the front. I use Sportec M3's and love them. The pressures run pretty similar...
Overall, on the road... it's pretty academic. At the stock pressure you can still run a good clip in the canyons and be fine... It boils down to personal preference and needs...
