Sidewall Punctures and Tyres Sizes Through the Years | Hometyre Mobile Tyre Fitting

As we progress through time, the average size of tyres is steadily increasing. In the late 90s the average size was 185/60R15. Through the 2000s, the size grew from 205/55R16 to 225/45R17. In this modern era with SUVs becoming more and more popular, we are starting to see a rise in 225/40R18 and even some 19 inch sizes becoming a factory default for certain manufactures.

As the size of the tyre increases, the sidewalls seem to be becoming slimmer and slimmer but nails and tacks somehow still seem to find themselves attracted to these areas. Unlike the main tread of the tyre, these areas are constructed of a multitude of thin chords that hold the pressurised air inside the tyre. If a nail enters this area, the chord is most likely damaged, and a puncture repair won't be able to save the tyre from a bulge and then an eventual blow-out.

This customer called in after their tyre had deflated overnight. After calling the office to choose a preferred date and time for their appointment, we ordered a replacement tyre and headed out to the customer's address. After removing the old tyre in preparation of installing the new Pirelli, we found that someone had attempted to repair this tyre on the sidewall in a previous life. It may have been sold to the customer under the premise of a 'nearly new' part worn tyre. Again, this is why we strongly advocate against part-worn tyres.
