Slow down when it’s raining to maximise grip on wet road surfaces

GEM supports Tyre Safety Month 2016 with the first in a series of straightforward safety reminders: Slow down when it’s raining, to maximise grip on wet road surfaces

GEM Motoring Assist is supporting Tyre Safety Month with the first in a series of simple safety reminders. We advise that grip on wet surfaces reduces as a tyre gets older, or as water depth increases, and the safest course of action is to reduce speed in wet weather.

Neil Worth, road safety officer for GEM, commented: “Tyre treads are designed to give the best possible grip on wet roads.  However, levels of grip generally decrease as a tyre gets older and its tread patterns wear down or as the depth of water increases. We urge drivers to take this into consideration and reduce their speed accordingly in wet conditions.”

Keep your tyres in check

Regular checks on tyre tread depth are vital for safe driving, according to Neil. “A car’s tyres must have a minimum tread depth of 1.6mm across the central three-quarters of the tyre, all the way around.  Few drivers have a tyre gauge to hand, so instead GEM suggests using the 20p test. “

The outer band of a 20p coin measures exactly 1.6mm, so place the coin between the grooves of your tyre and if the outer band is visible then your tyres need changing,” adds Neil.

“Tyre tread grooves are vital in wet weather as they assist in removing water from the area where your tyres are in contact with the road. Lack of tread depth compromises your ability to brake, steer and accelerate effectively, so your risk of aquaplaning and crashing increases.

Neil concludes “It’s not just a good idea to have adequate tyre tread. It’s the law. Drivers whose tyres fail to comply with the minimum tread depth requirements risk a fine of up to £2,500 and three penalty points for each illegal tyre.”
