Compact spare tyre
Tyre Size
T125/70 R18
If your vehicle is not equipped with a compact spare tyre, your vehicle will be equipped with a Tyre Mobility Kit.
NOTICE
• It is permissible to add 20 kPa (3 psi) to the standard tyre pressure specification if colder temperatures are
expected soon. Tyres typically lose 7 kPa (1 psi) for every 7°C (12°F) temperature drop. If extreme tempera-
ture variations are expected, recheck your tyre 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 tyre pressures in advance. If necessary, inflate them to a proper level
(Air inflation per altitude: +10 kPa/1 km (+2.4 psi/1 mile)).
• Must do not exceed maximum inflation pressure shown on equipped tyre sidewall.
When replacing tyres, use the same size originally supplied with the vehicle.
Using tyres of a different size can damage the related parts or make it work irregularly.
