The differences surprised us! Vehicles equipped with the 2/32 minimum tire tread depth took about 100 more feet to stop and were still traveling at about 45 mph at the same distance the vehicles equipped with the 4/32 deep tires had already come to a complete stop!
Therefore the vehicle's stopping distance increases. Although the legal minimum tread depth is only 1.6mm, independent research at MIRA shows that tyres with 3mm of tread have an average 25% better performance than those at 1.6mm-which represents an extra 8 metres stopping distance in wet conditions.
