I have the same size tires

I go with 37 front and 35 rear for street driving and 38 front and rear for track/fun driving. It does depend on the car though. Is this for your TT? The weight and balance of the car is very important to the equation.

Not sure.

What size tires did the ZX come with in stock form? Stock size on the TT is 225/45/17 and stock pressure is 36 front 33 rear. I would compare those pressures to the stock pressures for the ZX. If they have different tire sizes (I expect they do) it would be hard to compare.

Like I said,

it is very hard to know if the same pressures would work for both cars because of weight differences, suspension design and other factors. I would say try 36 all round and adjust from there. Take both cars through a few turns and see how they feel.

Take the Manuf. recommendations....>

And add 2 lbs as a start. Adjust to your liking from there. Chassis/suspension geometry, weight distribution etc. are all factored in to arrive at a recommendation for THAT car. All will be different.
