What is the legal minimum tyre tread depth in the UK? +
The legal minimum tread depth in the UK is 1.6mm across the central three-quarters of the tyre, around its entire circumference. However, most motoring organisations recommend replacing tyres at 3mm, as braking performance drops significantly below this level. Driving on tyres below 1.6mm carries a fine of up to £2,500 and 3 penalty points per illegal tyre — so four bald tyres could mean a £10,000 fine and 12 points.
How old can tyres be before they need replacing? +
Even if the tread looks fine, tyres degrade over time as the rubber compound hardens and loses grip. Most manufacturers recommend replacing tyres after 5 years of use, and no tyre should remain in service for more than 10 years from the date of manufacture. You can check the age using the DOT code on the sidewall — the last four digits show the week and year of manufacture (e.g. 2319 means week 23 of 2019).
Can I get tyres fitted at my home or workplace in Bicester? +
Absolutely. Mobile tyre fitting is one of the most popular services in Bicester. A fully equipped van comes to your home, workplace, or any safe location with the tyres you need. The fitter brings a hydraulic jack, wheel balancer, torque wrench, and all necessary equipment. Most jobs are completed in 20 to 30 minutes per tyre without you needing to leave the building.
What should I do if I get a flat tyre on the motorway? +
Pull onto the hard shoulder as far left as possible, switch on your hazard lights, and exit the vehicle from the passenger side away from traffic. Do not attempt to change a tyre on the motorway hard shoulder — it is extremely dangerous. Move behind the crash barrier if there is one, then call a mobile tyre fitter or breakdown service. If you are on a smart motorway with no hard shoulder, stop in an emergency refuge area.
Do I need to replace all four tyres at the same time? +
No, you do not need to replace all four tyres at once unless they are all worn. It is best practice to replace tyres in pairs (both fronts or both rears) to maintain even handling. The newer tyres should always go on the rear axle for stability, even on front-wheel-drive cars. Mixing tyre brands on the same axle is not recommended but is acceptable across different axles.
Can I get tyres fitted on a Sunday in Bicester? +
Yes, many mobile tyre fitters in Bicester operate seven days a week, including Sundays. Some garages also open on Sunday mornings. Weekend availability is especially useful for working professionals who cannot take time off during the week. Expect the same pricing as weekday fitting in most cases.
