Frequently Asked Questions
What are the current regulations for tyres in the UK, are my tyres legal?
A minimum of 1.6mm of tread in the central three-quarters of the tyre width, all the way around the tyre. The edge of the tyre may be worn down, but if any of the internal tyre cords are visible the tyre is illegal. Any bulges, deep cuts or cracks on the tyre wall or tread make the tyre dangerous and illegal.
How much does the level of tread on a tyre affect stopping distances?
Based on a car travelling at 50mph on a wet road...
- On 8mm tread depth, stopping distance could be 25.9m
- At 3mm the distance could increase to 31.7m
- With only 1.6mm the stopping distance could be a staggering 39.5m!
Do you have any advice for motorists about inspecting their tyres?
Inspect your tyres' condition regularly - pot holes & kerb contact may damage the tyre tread and walls. At the start of each day walk around the vehicle and visually check for tyre damage or low pressure on any of the tyres.
Why should I have my front wheels aligned (tracked) ?
The vehicle manufacture ensures that optimum handling, efficiency and tyre wear are achieved by engineering the suspension ‘set up’. Correct front wheel alignment should be maintained in accordance with the manufacturer’s specification. Wheel alignment can be disturbed by ‘kerbing’ and pot holes. If your vehicle ‘pulls’ to one side or the steering wheel is ‘off centre’ when driving along a straight road where there is neutral camber, or front tyre wear is obvious on one side of the tyre, then front wheel alignment may require attention.
Do You Have a Slow Puncture ?
Henley Tyres can find most slow punctures and repair them if the tyre is not damaged or when the puncture is not too close to the edge of the tyre tread. When ‘run flat tyres’ have been punctured they can not be repaired if the vehicle has been driven when the tyre is flat or has very low air pressure. Another reason why tyres may loose air pressure (normally aluminium wheel rims) is often due to corrosion on the inner side of the wheel rim, where the tyre seals onto the rim. Henley Tyres can resolve this problem and obtain an air tight seal in most cases.
Are all makes of tyre the same - black and round!?
Most certainly not! 'Branded' Tyres (eg: Bridgestone, Dunlop, Continental, Firestone, Goodyear, Michelin, Pirelli etc.) are manufactured with better quality material and are designed to offer maximum grip! Tests have proven that branded tyres could possibly stop your vehicle 13m sooner than 'quality' budget tyres. A branded tyre could possibly stop your vehicle two car lengths shorter in the wet when compared with a less-expensive tyre!
When should I change my tyres?
The UK legal tread depth limit is 1.6mm in the central three-quarters of the tyre - all the way around. If the edge of the tyre is worn with internal canvas showing, the tyre is dangerous and illegal!
Which brand of tyres should I put on the vehicle?
Henley Tyres recommends that tyres are replaced at 2.5-3mm of tread with the same brand and type as fitted originally to the vehicle. This ensures you continue to enjoy the handling and ride characteristics as when your vehicle was new. Alternative brands may be fitted, provided the tyre's specification is the same.
Why should I check my tyre pressures regularly?
Maximum grip, improved fuel economy and reduced tyre wear will be enjoyed if the tyre pressures are maintained correctly. You should check them regularly - particularly before long journeys. Vehicle manufacturers have tested your vehicle at different tyre pressures and consequently recommend the pressures for normal and full load use of your vehicle.
Why do I Need to have Wheels Balanced & New Valves Fitted ?
When a replacement tyre is fitted to a wheel rim the wheel should be dynamically balanced to prevent ‘wheel wobble’. The symptom is normally felt via the steering wheel which may vibrate / shake at certain speeds. If ‘wheel wobble’ is present the front wheels should be rebalanced. This will also prevent excessive wear on suspension and steering components. When new tyres are fitted always ensure a new valve is fitted (old ones can perish and leak air) and that wheels are ‘dynamically’ (not statically) balanced to ensure a smooth drive. Henley Tyres fit new valves and dynamically balance wheels, all within the quoted price.
