TYRE SAFETY

2 1 Most of us operate motor vehicle on a daily basis and hardly ever pay any attention to one of the most vital part of the vehicle which are our tyres. TYRE SAFETY

3 Did you know that tyres expire 4 years after the date of manufacture and this date is stamped on the side of the tyre? TYRE SAFETY

4 It is very easy to find out the expiration date of a tyre, if you check on the side of it, you will have a 4 digit number stamped on it, this number indicates the week and the year it was manufactured, the expiration date will be 4 years later. TYRE SAFETY

5 This number indicates that the tyre was manufactured on the 7 th month of th month of the year “July” Year of manufacture “2007” TYRE SAFETY

6 If we use expired tyres these are likely to burst and result in a very serious or even a fatal accident, it would be a good practice for us to check our tyres and make sure they have not passed their expiration date TYRE SAFETY

7 Another important point, at most of the gas stations they calibrate your tyres at 28 PSI and if you are going to travel in many cases they bring your pressure down to PSI because tyres will “heat up on the highway and the pressure will come back up”. DO NOT ALLOW THIS TYRE SAFETY

8 On the side of the tyre, you will also find the maximum allowable inflating pressure for that specific tyre, some tyres have a maximum pressure of 32 PSI some are rated at 44 PSI and some even at 50 PSI. Check your specific tyre to see what the maximum pressure is for your tyres, it is an acceptable practice to have your tyres a few pounds below maximum allowable pressure but not too much. TYRE SAFETY

10 Another important point to consider is the load we put on our tyres, many times we overload our vehicles without paying any attention how much stress this puts on our tyres, exceeding the maximum load rating on a tyre may also lead to tyre failure and could result in an accident. TYRE SAFETY

11 Attached table shows the load index and maximum load carrying capacity per tyre in pounds and kilograms. TYRE SAFETY

12 Load index 109 maximum load capacity 2271 lbs 1030 kg. TYRE SAFETY

13 The speed rating for which a tyre is designed is indicated by a letter next to the load index, adjacent table shows the speed ratings in Km/h & Mph. TYRE SAFETY

14 Many of us have bought tyres in the past and when they ask us the size of the tyres we just read it from the old tyre and give them to the person at the tyre shop but, what do those numbers mean? TYRE SAFETY

16 TEMPERATURE RESISTANCE The letters will indicate a tyre’s resistance to heat. Tires are rated from highest to lowest resistance as A, B or C Simbolo SymbolArea A Hot area Area Caliente B Normal Area Area Normal C Cold Area Area Fria TYRE SAFETY

17 TRACTION Traction is a tyre’s ability to stop on wet pavement. A higher graded tyre should allow you to stop your vehicle on a wet road in a shorter distance than a tyre with lower grade. Traction is graded from highest to lowest as ”AA”, “A”, “B” and “C” TYRE SAFETY
