How the job is done
A blowout on the A40: get safe first, then we bring the tyre.
Western Avenue carries traffic at dual carriageway speeds between the Target roundabout and Denham, and the Oxford northern bypass is similar between Wheatley and Wolvercote. A tyre that bursts there tugs the car sideways, often beside a coach or van. Hold a straight line, lift off rather than braking hard, and indicate for the exit: the A4180 for West Ruislip, Swakeleys for Hillingdon, Marston for Oxford. On the elevated Westway, stopping anywhere before Wood Lane is out of the question.
If the car cannot go on, keep out of the traffic, move behind any barrier and call 999, then TfL on the London section or National Highways on 0300 123 5000 on the bypass. When the car is parked at a safe spot, WhatsApp the tyre size and location. The fitter brings a new tyre and fits it, then inspects the wheel rim for splits and the other tyre on the axle for heat damage.
Our Brent Cross team also offers emergency mobile tyre fitting, flat tyre help and 24 hour tyre repair on the A40.
