Hyundai Equus: Tires and wheels

CAUTION

When replacing tires, use the same size  originally supplied with the vehicle. Using tires of a different size can damage the related parts or make it work irregularly.

✽ NOTICE

It is permissible to add 3psi to the standard tire  pressure specification if colder temperatures are  expected soon. Tires typically loose 1psi for every 12°F temperature drop. If extreme temperature variations are expected, re-check your tire pressure as necessary to keep them properly inflated.
