Shallow Tread Depth
When the depth of the tread on your tyres gets shallower than 3mm, they will no longer be able to gain enough purchase and friction on the roads to keep you safe. To avoid scary sliding and bad driving in wet conditions, you need new tyres with a deeper tread.
If your driving experience has started to become rather ‘shaky’ over time, then it might be down to the fact that your tyres are no longer even on all four corners. A fresh set that are all equal in size and quality will restore that smoothness that you would have been used to from before.
Visible Tyre Cracks
Small signs of wear and tear are normal in healthy tyres, but if you start to see cracks that are visibly deeper than normal, it is a clear sign to get rid of those and opt for a new batch. Those cracks aren’t going to go away or get better.
Bulges In Your Tyres
If there are any weird bulges across any area of the tyre, then it is a key sign that something has been damaged internally that isn’t going to fix itself. Time to get to the nearest garage!
