Tyre

Hi, any advice why my 6 months old CSC 5 [all 4 pieces] always loose pressure? I pumped 220 and it can become 190 after 1 week!  :-(

 

If only we could loose our weight that easily......

Might got crack on your tyre. My csc3 also always air leak within 3 days. 280 to 200-190 dash ring liao

check your tire valves too

If you pumped the tyres after driven the car for more than 15 min(estimate) and checked when the tyres are still cold, then likely the pressure would be lower.

What happened here is that you topped up air to the tyres when they were hot....

For W204 stock 17" wheels, the preferred tyre pressure for CSC5 is 30PSI for frt & 33PSI for rear. The correct way of topping up air for the tyres is to compensate an extra 2-3PSI, depending on how hot the tyres are. The longer you drive till the tyre kiosk, the hotter it gets, hence the higher the pressure. The next morning before driving off, use your tyre pressure gauge to check the pressure when cold....usually you'll need to bleed a little air to achieve the right pressure. Always monitor the tyre pressure in the morning consistently.

Buy an electronic pump, connect to ciggie lighter and pump yourself in the morning when cold. Then you will have the correct pressure. Check every week to make sure no leak.

There are cracks internally... you will not see them unless u remove the tyre from the rim... I guess it's only one tyre?... common case with CSC... that's y I don trust them anymore. ...
