Find the right tyre size for the 2014-2020 Mercedes-Benz GLA — match against your sidewall before booking a fit.
About this generation
Mercedes-Benz fits run-flat tyres on many GLA 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.
This generation of the GLA 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.
Chassis code: X156. Use the chassis code to confirm you have the right generation when ordering tyres.

Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
Do I need SUV-rated tyres on the 2014-2020 Mercedes-Benz GLA?
SUV-rated tyres carry a higher load index for the extra weight and ride height. Match or exceed the original load index. If you do mild off-road, all-terrain (A/T) tyres trade some on-road grip for better unpaved performance.
Are all-season tyres suitable for the Mercedes-Benz GLA?
All-season tyres carrying the 3PMSF snowflake symbol are a sensible choice for UK Mercedes-Benz GLA drivers who don't want to swap between summer and winter sets. Confirm the size and load rating match your OEM spec.
What do star/OEM markings mean on Mercedes-Benz GLA tyres?
Mercedes-Benz approves specific tyres for many of its models, marked with a star (BMW), MO (Mercedes), AO (Audi), J (Jaguar) or similar. OEM-marked tyres are tuned for that car's suspension and don't always come from the major brand-name fitter as a stock item — they may need to be ordered.
What wet grip should I look for on the Mercedes-Benz GLA?
For UK driving conditions, prioritise an EU tyre label wet-grip rating of A or B. Wet grip directly affects braking distance — the gap between A and E ratings can be more than a car length at 50 mph.
Did the 2014-2020 Mercedes-Benz GLA come with run-flat tyres?
Many Mercedes-Benz models in this era were supplied with run-flat tyres from the factory. If your car has tyre pressure monitoring and no spare wheel, replacement tyres should typically also be run-flat. Verify on the existing sidewall — look for "RFT", "ROF", "ZP" or similar markings.
