The standard load indexes of these two tyre sizes are different, so the 45 aspect ratio tyre needs more air pressure to support the same weight as the 50 aspect ratio tyre.

 

The 205/60R16 tyre size on the Kamiq has the same load index as the 215/50R18 tyre size on the front wheel drive Karoq...as shown in the chart below.

 

Standard Load index of tyres

205/60R16 92(630kg)

215/45R18 89(580kg)

215/50R18 92(630kg)

 

Those weight figures are at 2.5bar.

So it doesn't make much sense that that's the normal pressure for Kamiq, and the pressure label on the car suggests even higher for a fully loaded car.  Baffling.

For the 92 LI tyres, the 630Kg is also at 2.5bar.  Karoq label says normal pressure is 2.1bar, which is 550kg.

It's a slight oddity with XL tyres, but something to aware of it you replace standard tyres with XL tyres, that their rated load capacity is at 2.9bar.  At lower pressures their load capacity is bit lower than standard tyres at the same pressure.
