The tyres on your car are the wrong size.

This is important because your speedometer is out, as is your odometer.

Standard size is 235x45x17.

By all means change your tyres, but do it properly and keep them within the tolerance on the dynamic rolling radius or get your car reprogrammed to match.

If you're asking for the correct tyre sizes to fit then anything that has a dynamic rolling radius the same as or +/- tolerance of 2.5% of the standard 235x45x17.

I have 235x35x19 on the front and 265x30x19 on the rear.

Check on these two sites if you want to see what they'll look like from the side or above respectively as these are visual comparative sites.
