증상
큰 휠과 저프로파일 타이어로 변경했을 때 타이어 공기압을 어떻게 설정해야 하는지에 대한 질문. 일부 운전자들은 포트홀 등 악조건 도로에서 휠 손상을 방지하기 위해 제조사 권장 공기압(예: 2바)보다 훨씬 높게(3~4바) 증가시키는 것이 좋다고 주장함. 휠이 타이어에 더 가까워지므로 포트홀 충격 시 손상 위험이 감소한다는 논리.
처리 내용
제조사의 휠/타이어 사양에 대한 공기압 권장사항이 있으면 그것으로 시작해야 함. 새 휠이 제조사 권장 크기보다 크고 타이어가 더 얇으면 직접 조정, 연구, 계산을 통해 최적값을 찾아야 함. 공기식 타이어는 서스펜션 시스템의 주요 언댐프드 스프링 역할을 하며, 타이어 내 공기량이 돌, 범프, 포트홀 같은 충격을 흡수하는 1차 방어선. 공기압이 너무 낮으면 포트홀로 인해 새 림이 휠 수 있음. 하지만 공기압이 너무 높으면 공기식 타이어의 이점을 상실하게 되며, 휠+타이어 서브시스템의 성능이 저하됨.

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
