\nAnd not forgetting the all-important wedding ring. Check!<\/p>\n

It’s down to the last few days before Duncan and Petunia tie the knot, and it’s vitally important that everything runs smoothly. Duncan is on a mission to collect Petunia’s wedding ring from the jeweller when he realises that he needs to change his tyres<\/a>, especially after their last risky encounter<\/a>\u00a0on the roads.<\/p>

<\/div>\n

Without the slightest idea of where to begin, Duncan pops into his local Dunlop Zone one day on his way home to Germiston for some advice on replacing his car’s rubber.<\/p>\n

“Just as your wedding ring indicates that you’re married to someone, the markings on your tyres tell a story too,” the Dunlop Zone expert explains.<\/p>

<\/div>\n

Duncan notices the following series of numbers and letters on his tyre:<\/p>\n

225 \/ 45 R 17 94 S<\/h3>\n

“What do these markings mean?” Duncan asks.<\/p>\n

\"duncan-the-dunlop-tyre-guy\" Tyre width – 225<\/h4>\n

Simply put, this refers to the width of the tyre in millimetres.<\/p>\n

\"duncan-the-dunlop-tyre-guy\"<\/p>\n

\"duncan-the-dunlop-tyre-guy\"\u00a0Sidewall height – 45<\/h4>\n

This isn\u2019t an absolute measurement, but instead indicates the sidewall height as a percentage of the tyre width.<\/p>\n

\"duncan-the-dunlop-tyre-guy\"<\/p>\n

\"duncan-the-dunlop-tyre-guy\"\u00a0Radial-ply construction – R<\/h4>\n

Radial-ply construction was first patented in 1915 and is now the standard tyre design for wheels on passenger vehicles, as it allows for better fuel economy and ride comfort, as opposed to other tyre designs.<\/p>\n

\"DUNLOP_WEEK_4_4\"<\/p>\n

\"duncan-the-dunlop-tyre-guy\"\u00a0Rim diameter – 17<\/h4>\n

Wheel rim sizes range anywhere from 14″ right up to – believe it or not – 40″. Duncan’s wheels clock in at the reasonable end of the scale at 17 inches.<\/p>\n

\"duncan-the-dunlop-tyre-guy\"<\/p>\n

\"duncan-the-dunlop-tyre-guy\"\u00a0Load index – 94<\/h4>\n

The load index can also be considered a ‘weight rating,’ as it determines how much weight the tyres are able to carry. A load index of 94 means that Duncan’s tyres can carry up to 670kgs.<\/p>\n

\"duncan-the-dunlop-tyre-guy\"<\/p>\n

\"duncan-the-dunlop-tyre-guy\"\u00a0Speed rating – S<\/h4>\n

Last but not least, the speed rating tells us the speeds that the tyres are capable of achieving. In perfect conditions, Duncan could go up to 180km\/h, with his tyres rated ‘S’. Remember that despite these speed ratings, you are still required to observe the national speed limit of 120km\/h.<\/p>\n

“Think about sidewall markings as unique identifiers, similar to the identification numbers that you and I possess,” the Dunlop expert says.<\/p>\n
