cos of colder weather , i mean less +30 , as they dont heat up much when driving is recomended to keep pressure higher . im not in psi numbers , but would keep about 2.4 - 2.6 bar on low profile tires

have very good experience on this on few different cars . if with less pressure about 2.2 -2.3 bar , rear tires would wear bit from inside ,with perfect suspension components and tracking ,so after with higher pressure they wear ideally - perfect 100%
