I have it on expert authority (SSL) that 22psi is plenty for the front.
My first question would be how old are the tyres? Many people find a vast difference with new rubber, so if they are 8 years old or so, worth changing anyway as rubber hardens over time.
Also, exactly what do you mean by uprating the suspension??
One further thought, with the front jacked up, can you spin the steering wheel with one finger in the steering wheel spokes?
