TYRE TIPS

If you get a puncture
If you puncture the 3 things that can let you down and leave you desperately stranded are:
Locking Wheel Nuts - If you have them fitted do you know where the tool is?
Jack - Most car jacks seize up because they are never used. Just once a year, lubricate the thread then wind it up and down to free it off.
Spare Wheel - When did you last check to see if it was legal & inflated?

Legal requirements
The legal limit for minimum depth of the tread on your tyres is 1.6 millimetres, across the central 3/4 of the tread around the complete circumference of the tyre.
For safety reasons it is recommended that you replace your tyres before the legal limit is reached. Many vehicle manufacturers recommend replacing at 3 millimetres. At 1.6 millimetres in wet weather it takes an extra car length (8 metres) to stop at 50 mph than if your tread was 3 millimetres.
Importance of correct tyre pressures
The main reasons for maintaining the right tyre pressures are:
* Safety - Tyres that are either over or under inflated do not have the same levels of grip as ones that are correctly inflated
* Economy - Tyres with the correct pressure do not wear out so quickly.
Also vehicles with under-inflated tyres have a higher rolling resistance which increases the engines fuel consumption
We do not charge to set tyre pressures
Space saving spares
'Mini spares' are designed to take up less room in your vehicle and to get you home, but not to be driven on for long periods. Many of the space savers can not be used at speeds over 50mph; consult your space saver wheel or vehicle handbook for specific details

Run flat tyres
Run flat tyres enable vehicles to be driven, at reduced speeds for a limited time until they can be replaced. These are specialist tyres with reinforced sidewalls allowing the tyre to support the vehicles weight even when all the air has escaped

General
It is preferable to have the same tyres all round - Or at the very minimum the same from side to side (same axle)
Never change a tyre on a motorway or busy dual carriageway especially if it's on the off side of the vehicle (driver's side)
