Anyone on here know how much air should be in my tyre?

 

I have 255/35 zr18 90w writtten on the tyres wall.

 

There was 30 in them when i got back from the garage after having one repaired.

 

Is this too much? I have no idea where to find out!!

I have two sets of wheels stock 17's and 18s with 10.5 inch rear running 285 at the rearand 9 inch 245 fronts.

 

I have used 33 psi rear and 34psi front for about four and a half years. I have used 3 sets of fronts and 5 sets of rear tires and all have have shown even rates of wear acoss the tire surface. No issues with grip, barring the usual wet high power RWD in the wet type stuff.
