2020 GLE 450 4MATIC
Wheel size variation coding
My 2020 GLE 450 came equipped from factory with 19" wheels and 255/50R19 tires. The previous owner had 20" wheels (non-OEM), which I replaced with AMG 20" wheels with 275/50R20 tires.
By using a VIN decoder I found the variation in my car is 9U4 Control code, wheel diameter, standard (size 750/760).
From another car with original 20" wheels and 275/50R20 wheels, the variation is 9U5 Control code, wheel diameter, medium (size 790).
I connected a scanner to code the correct variation for tire size and found the following :
Instrument Cluster (IC) → Variant Coding → Wheel Size
with these options
Wheel Size 1
Wheel Size 2
Wheel Size 3 (this one already selected, I left it unchanged)
Does anyone know which tire sizes correspond to each option? Was my car already coded for the right tire size?
