Picked my new Arona up 3 weeks ago & still cannot find correct tyre pressures. The sticker on the inside of the passenger door refers to 18inch wheels but mine has 17 inch wheels, so surely these do not refer to my vehicle. Checked the pressures today & they were 40psi in the front & 38 psi in the rear. No wonder the suspension felt hard! Does anyone have any idea what the tyre pressures should be for my model?
