Dear all,I have been having this problems with my 2 front rims for the past months until now cannot bear with it anymore......Every 2 - 3 days, my tyre pressure of both the front tyres drop from 220 to 130 , and the steerling feels damn heavy naturally, so every 2-3 days must "pump" my tyres. btw, I am using 195/50/15.I had no problem with these 2 tyres/rims previously when I was using Good Year tyres, until before CNY, I changed to Continental, that's where the problem starts.I had even sent my rims for repair and do some skimming , but still can't solve the problem.Anyone had a better solutions for me or can recommend a good Rims Repair shop ?Am thinking of using those tyre rescue solution .............. :unsure:
