Hi,
Anyone wishing to know about recalls , get in touch, my car has had so many warranty jobs on it. Its been rebuilt.
Any problems with your own cars I can probably help, as its already probably happened to mine.... :(
It doesn't sound as if you're far from optimum if you managed 28K, but I'd still be tempted to try 38 psi in the fronts as well and monitor the wear pattern. If you start to get more wear in the centre of the tyre then knock it back a little. The wear you get will also depend on the average journey you do. What's your typical journey? Long duration motorway or short duration mixed roads?
