2 x new pilot sp installed 30 days ago !!! :-(

highlander777 · 12-20-2006, 03:56 PM

I had 2 x Pilot Sports Run flats installed about 1 month ago. I have noticed that both have lost a lot of air so I put more in 3 days ago.

So I put 2.7 bar and today they have both gone down to 2.45 and 2.4. This seems like a lot. I am wondering if the tyres were installed incorrectly.

Can anyone offer any advice?

The most common installer caused leak will be from the valve stem. The other will be a tear on the bead seat, but the leak is typically more dramatic.

Check the valve stem and also search for nails. Or simply bring your car to a local tire shop.

conversion: leak decreased psi from 39.15psi to 34.8psi

Yea, have a reputable shop put a tire in the dunk tank. Should easily find the cause if you are losing 5psi a day....
