Through a family friend have just picked up a mint WRX v limited on an M plate , low miles as was owned by a member of the military and he spend most of his time overseas , the car has been fitted with a set of sti 3 / uk turbo rims and have had expensive refurb and some toyo`s fitted .

As the car has been stood for approx 8 weeks , the tyre presures are all over the place 25 psi to 33 psi , i will be doing fast road driving to and fro to work and little bit of dual carriage way at legal (cough) speeds , what pressures do i need ??

Thanks guys
