When vehicle is driven, what pressure I should inflate the tires to?
One guy at tire shop said +3psi - so 38psi - the guy inflated said it will be bumpy. Mine is 2013 Mazda 5 - Factory says 35psi.
When I was on freeway (38psi) it felt as if I didn’t have the benefit of the tire (it was so hard) - car was not gripping the road. Besides stuff inside the car was giving resonating vibration.
So next day on this trip, I used my finger nails to release the pressure - measured it after driven on freeway and it was 36psi all around!
Should I inflate to 35psi regardless? What do you guys do?
I do not want the car to float on the road (this is what I felt at 38psi) - I like the car to hug the road as far as possible and not to have a vibrations. Same time, I do not want the tires to wear out unevenly - what is the optimum?
