증상
타이어의 하이드로플래닝(수막 현상) 발생 가능성이 타이어 공기압과 어떤 관계가 있는가? 과도한 공기압 또는 부족한 공기압에서 하이드로플래닝이 더 잘 발생하는가?
처리 내용
NHTSA 자료에 따르면 하이드로플래닝 발생 속도 계산 공식: 하이드로플래닝 속도 = 10.35 × √공기압(psi) 예시: - 30 psi: 시속 56.7 mph에서 하이드로플래닝 발생 가능 - 25 psi: 시속 51.8 mph에서 하이드로플래닝 발생 가능 - 20 psi: 시속 46.3 mph에서 하이드로플래닝 발생 가능 결론: 공기압이 낮을수록 하이드로플래닝이 더 잘 발생한다. 주요 원인: 1. 저압 타이어는 노면과의 접촉 면적이 크므로 타이어가 노면에서 들뜰 때 필요한 수압이 낮아진다. 2. 저압 타이어는 노면에 오목한 형태로 접하므로, 타이어 아래 갇힌 물이 타이어 중심선을 향해 흐르면서 물을 배출하지 못한다. 반대로 고압 타이어는 낮은 접촉 면적으로 인해 물을 더 효과적으로 배출할 수 있다.

Almost my entire car history, three trip reports from Euro road trips and and a tale of love and heartbreak featuring a black R8 can be found in this previous thread:https://www.pistonheads.com/gassing/topic.asp?h=0&...Then we bought a black Porsche Cayman 981 GTS and did another Euro trip:https://www.pistonheads.com/gassing/topic.asp?h=0&...But...I got bored and started idly searching for alternatives. I've gone into details in that thread; the Porsche was lovely but just not putting the sauce on my chips. So once again in order of importance, must haves were: Not another furking black car

Friday and the first time I'm out for a drive by myself. BBB was hanging with the famalam in Hereford and then meeting me at the narrow boats down in Llangattock, so I was exploring South Wales via all the two lane B roads I could find. I hope you're ready for some Audi Porsche Aston on a mountain moor pictures! https://maps.app.goo.gl/FxSVcrKpmJVQ5G4v9?g_st=acFrom Hereford I went via the B4352 which was nice and twisty with no traffic. I was building speed, warming tyres and trying to get used to the car. 3rd gear was the one and I was loving the oodles of torque compared to the Porsche. And
