Morning Richard

Welcome to the Forum

When you say "maximum" tyre depth are you looking at the side wall (between the ground and the wheel rim) ?

Those tyre sizes are correct for the wheels you have, however depending on build spec and country 16" wheels fitted with 205x55x16 front 225x50x16 rear or 225x45x17 front 255x40x17 rear (Note both theses options also came as a set of 4 wheels same as the front size) 18" were also available in225x40 front and 255x35 rear

If you are considering a wheel change check care fully the the new wheels fit with the brakes on your car

If you are asking because you are finding the ride hard/harsh then there are some additional things to check Suspension starting with springs (are they stock) Shock Absorbers as they age they may harden in action Suspension Bushes these are rubber and again harden and crack giving a harsh jolty ride

Hope this helps not hinders 😁
