Ideal Tyre Pressure for Upsized Santro Tyres?
I have a 2001 Hyundai Santro and I changed its tyres a year ago. The previous ones were Pirelli P400 Aquamile P155/70R13 75T, which may also not have been the original set the vehicle came with (I don’t remember).
The ones I am now using are Hankook Optimo H418 175/65R13 80H Tubeless tyres, and two of them have had tubes inserted in them. The sticker on the car’s side pillar suggests maintaining 30 psi on all tyres, and that’s what I’ve been doing so far, but is that ideal anymore, now that the tyres have been changed?
