About this generation
This generation of the GLS runs on 19-inch or larger wheels in some trims, which means short-sidewall tyres that handle precisely but are less forgiving on rough UK roads.
Mercedes-Benz fits run-flat tyres on many GLS models, paired with tyre pressure monitoring and no spare wheel. If your car was supplied with run-flats, replacements should typically also be run-flats.

The GLS uses 19" or larger wheels — what should I know?
Larger wheels mean lower-profile tyres with shorter sidewalls — that means firmer ride, more pothole sensitivity and shorter tyre life on UK roads. Premium tyres usually repay the extra cost on cars with 19"+ wheels.
