3 CLIMB TEST
We decided to deflate the tyres to 1.5 bar and to climb the obstacle – a long, steep incline that starts at 30 degrees and ends at about 40 degrees – in first gear, low range. The test started at a pressure of 1.5 bars, after which the tyre pressure was increased incrementally. If a tyre could climb the slope at 2.2 bar without losing traction, it was considered a 100% pass mark. To our surprise, all the tyres got it right. Which only confirms that most tyres have enough grip for most applications.
