Hyundai Ioniq (AE): Specifications, Consumer information and Reporting safety defects / Tires and Wheels

NOTICE
- It is permissible to add 3 psi to the standard tire pressure specification
if colder temperatures are expected soon. Tires typically loose 1psi (7kPa)
for every 12°F temperature drop. If extreme temperature variations are expected,
recheck your tire pressure as necessary to keep them properly inflated.
- An air pressure generally decreases, as you drive up to a high-altitude
area above sea level. Thus, if you plan to drive a high-altitude area, check
the tire pressures in advance. If necessary, inflate them to a proper level.
(Air inflation per altitude : +2.4 psi/1 mile)
NOTICE
When replacing tires, use the same size originally supplied with the vehicle.
Using tires of a different size can damage the related parts or not work properly.
