34-35 strating seems a bit high for me,
4 laps of winton 2 weeks ago, I was slack started at 36 psi and had them at 44 by end. and car felt as shite as it should have by then.
normally I start around 32ish for warm up knowing I'll be around 18-40 after a good session then drop them to 36ish as soon as come in from first hot session.
then check them after each session to try keep around the 36 area.
end of the day adn I let them cool I'm around 28-29 but don't really recommend going out at that press on street tires, work your way up.
