Punto E+, stock tyres, 36500 kms done so far. I saw this damage on the front right side tyre yesterday. No air pressure loss, no wobbling, no pulling to left/right. No other problems so far. How serious does it look and is it safe to drive with this tyre for the rest of its life (may be another year or two) ? I can see some threads in the damaged area. Will there be problems in future when water/moisture goes into this damaged part? Please suggest what can be done to fix this problem.
