But are all of you 100% sure that tire pressure doesn't affect grip? Anyways, I've read that tires with high pressure tend to wear down faster from the centre than from the sides. Do you strongly recommend me inflating my tires way further than those recommended by the manufacturer? (I think maximum PSI for my tires is 50. Must check).
It's quite strange that I don't lose any grip with a higher tire pressure.
So, what pressure would you recommend me, if my car weights a total of 1370 kg + 55 kg (me)?
Keep in mind that sometimes I'll carry up to 5 people + charge in the trunk (+350 kg)
