Hi. i have a Range Rover Vogue 2003 L322 and i recently fitted two rear Hankook 285/35 r22 tyres and i was wondering what the correct tyre pressure is.

I've done some searching but i keep seeing people recommend between 30-40 psi and was hoping i could narrow it down.

 

Recommended tire pressures can be found on a chart located on the driver's door or on the B-pillar below the driver's door latch. These are recommendations and what you choose to run can be either the pressure listed on the chart or about 85-90% of the MAX pressure listed on the tire itself.

These recommendations are for city and highway in good conditions. In poor conditions such as mud, snow, rocky mountain passes, etc. some drivers lower tire pressure to as little as 5 PSI to gain traction, but of course this is not recommended for continuous high speed driving. Some drivers choose to go above recommended pressure to increase fuel economy. There are really no rules regarding tire pressure except one: NEVER exceed the MAX pressure listed on the tire sidewall.

Also, why only two rear tires? If the vehicle is full time 4WD or AWD and there is a significant size difference is tires, expect driveline and transmission problems in the future. 4WD and AWD vehicles should have tires replaced in sets of 4 in one of the stock sizes and if the size is different than stock the spare should be matched to the new size as well.

 

does tyre width affect the pressure?
