Then you go out on the road and drive around for a while until your tyres are hot, then check them with one of those little Run Flat Tyres Penrith pressure gauges - presuming your car even comes with one! The pressure is often at least ten per cent lowYou may have seen these gauges before, but they look pretty complicated to use, so you never got used. Well, now's the time because it could save your life...Many believe that over-inflating tyres do not improve mileage or reduce rolling resistance. The correct tyre pressure depends on the type of tyre, its design and shape, but also factors like weight (load), wheelbase (wheel track) and axle location (tyre friction circle). Over-inflated tyres are more rigid - like a balloonThis increases lateral forces when cornering which will transfer more load to the outside wheel, reducing grip on that wheelAt the same time, under-inflation gives less rigidity (more deformation of the sidewall) allowing better grip across the whole tread faceLateral forces in corners will cause under-inflated tyres to roll onto their outer edges increasing wear on those areas;In contrast, over-inflation causes them to wear more along the middle of the tread pattern.Many people fear over-inflation because the Run Flat Tyres Penrith look 'bumpy' or stiffer to drive on. This is usually caused by incorrect tyre pressures, either too high or too low. The optimum tyre pressure level will give you a smooth ride and maximum grip around corners. It does not make any difference whether your tyres are under-inflated, over-inflated or at the correct pressure about each other (if they're directional tyres)Whether they're radial ply, diagonal, bias-belted or tubeless makes no difference either; but what's important is that your car was designed for those types/brands/models of tyres - it's your responsibility to ensure this when you choose which ones you want mounted on your wheels.Under-inflated tyres :;Under-inflated tyres are the leading cause of most tyre failures on modern radial-ply tyres, driving too fast for conditions and cornering hard. Under-inflation adds to the effects of sideways forces in cornering causing excessive heat build-up in the affected areas on either side of the tread pattern which eventually leads to failure.This is often caused by people filling their cars at 'The $1 Shop' because they can get four pounds off a full tank and it only takes five minutes if you put air in all four tyres to suit. Drive around like this for several tanks of fuelYou'll probably be lucky enough to make it home alive after an incident caused by one or more under-inflated tyres (or by not using a tyre pressure gauge and checking them regularly).What are the ways to choose a tyre pressure gauge?;We recommend the slim analogue type if you want to test your tyre pressures. Digital gauges give readings about ten per cent off as they cannot measure air accurately in psi unitsIf you use digital gauges it's even more important to keep records as these gauges will only tell you if one or all of your tyres is under-or over-inflated, but won't tell you which one(s) until the worst happens - then it may be too late!;The most accurate digital tyre pressure gauge we have tested so far was a Topeak Pocket Pro which came with a five-year warranty. For less money, they sell an analogue Topeak Pocket Pro which is still very accurate and comes with a generous three-year warranty.What to do after using a tyre pressure gauge?;After use, the tyre pressure gauge should be thoroughly cleaned to remove any oil from your fingers that may contaminate future readingsThe best way to clean them is to use methylated spirits (denatured alcohol), or even lighter fluid available from service stations or garagesThese chemicals evaporate quickly leaving no residue behind, but beware of sparks from open flames when using these in unventilated areas - alcohol has an extremely high flashpoint so you don't need to worry about fire hazards outside!;Cleaning instrument parts in-situ can sometimes cause more problems than they solve, whatever method you choose just make sure the Tyres Penrith pressure gauge is completely dry before use.Recommended average car tyre :;An average car Tyres Penrith has a load limit of around 100 psi, so there's no need to inflate your tyres beyond that with ordinary pump gauges. Use an accurate analogue or digital tester if you want to know exactly how much air pressure your tyres are running at - that way they'll still give excellent performance without being overloadedDo not forget to check spare tyre inflation pressures when you have finished with all four wheels! If you measure the cold inflation pressures on any of these, make sure you allow for the warming up as per our 'cold vs hot tyre pressure' article aboveMake sure you re-check your tyre pressures every month or two during winter months, especially if you live in a colder climate where it's common for tyre pressures to decrease by as much as 1 psi (6 kPa) every month." ]
