“When the tread depth reaches 3mm, take care to monitor the tread depth that remains since tyre grip on wet roads is markedly reduced below this depth.   Ideally replace your tyres soon after the tread depth reaches 3mm.”
The AA Foundation for Road Safety Research and the County Surveyors' Society - 2004

“If the Government and the Police change before reaching 1.6mm, it makes you wonder why that’s the legal minimum.”
Kevin Delaney, RAC Foundation

“These findings show for the first time how dramatic the reduction in braking performance can be between tyres with 3mm and 1.6mm of tread at motorway speeds in the wet…”
Chris Wakley, TyreSafe 

“You can dramatically reduce the likelihood of aquaplaning by changing tyres when they reach the 3mm level. At the legal 1.6mm, you’ll have little or no wet weather performance.”
Drive & Survive, Oxford based driver training company

“You can feel it shake a bit and basically you’ve got no control. It’s floating around like it’s on ice on 1.6mm.”
Matt Watson, Features Editor Auto Express magazine

“I think I’ve got fast reactions but I didn’t realize how long it would take to stop. I was amazed… it felt like it was on ice almost. I felt completely and utterly out of control.  It doesn’t bear thinking about if this happened on the road, if you had kids in the car or something. It’s quite shocking. I’m certainly going to change my tyres more regularly and put some nice fresh ones on if it’s going to make that sort of difference and I am going to keep my distance from other road users for definite now – it’s been quite a lesson.”
