TYRE
MARKINGS GUIDE
When replacing your tyres its important to make sure that you purchase
the right one. Brand names aside there still a criteria to meet. So
how do you know what to buy? Of course when you take your car to a
tyre fitter he can tell you but if you wish to do some research first
and compare prices etc then you need to know what to look for.
On the side of the tyre are some markings which can tell you all you
need to know. A handy one is the date of manufacture so that you can
see how well your current brand of tyre is wearing and how long they
are lasting you - Also you should never use a tyre that is older than
6 years old. Remember a softer tyre can give more grip but wear out
faster. Dont get a tyre that can not match the speed of the vehicle
and beware buying wider tyres just because you think that they look
better. Your wheel rims have a maximum tyre width that you should
adhere to. Just hold your mouse over the markings below to find out
what they all mean.
Check Tyre Pressures
Simply choose your car from the drop down lists below to find the
correct tyre pressures for your vehicle. Remember that incorrect tyre
pressures can affect the handling of the car, the stopping distance
as well as increasing wear on the tyres and increasing petrol consumption!
Vehicle wheels rims are usually described with a designation of something
like '13-5.5J' and this is decoded as follows. The 13 is the
diameter of the wheel in inches from edge to edge, measured inside
the flange with sizes ranging from 10 inch on the original mini's
to 23 inch on 4x4 vehicles. The second number is the width of the
rim, again measured in inches between the flanges.The letter, in this
case J refers to the shape of the rim. Rim contours are standardized
by the Tire and Rim Association, so that tires will fit.
