The Mercedes-Benz GLA is the entry-level compact crossover in Mercedes' SUV lineup, a stretched version of the A-Class designed for five passengers and modest cargo. It's available in GLA 250 (base), AMG GLA 35, and AMG GLA 45 S. The GLA sits on smaller wheels than mid-size and full-size Mercedes SUVs, with base 18-inch fitments and optional 20-inch AMG upgrade wheels.
GLA Tire Sizes by Trim
The GLA 250 ships on 235/55R18 tires on standard 18-inch wheels. Optional 19-inch wheels use 235/50R19, and a 20-inch option uses 235/45R20 — all square setups allowing full rotation. The 235-series width is narrower than most performance SUVs in this class, keeping the GLA light and fuel-efficient.
The AMG GLA 35 uses a wider AMG-specific wheel/tire package than the GLA 250 — always verify the exact size on the door-jamb sticker for your specific build.
The AMG GLA 45 S ships on a low-profile 20-inch AMG wheel/tire package (verify the exact size on your door-jamb sticker) with torque-vectoring AWD. The low-profile tire gives the AMG 45 S very responsive steering feel at the cost of ride harshness over rough surfaces.
The Mercedes-Benz GLA is based on the same platform as the CLA and A-Class. In practice, the GLA 250 uses similar tire sizes to the CLA 250 and A-Class 220, so tire options for those models also apply to the GLA 250.
Best Replacement Tires for GLA 250
For 235/55R18: the Michelin Primacy Tour A/S is the top comfort-priority all-season in this size — quiet, long-wearing, and well-suited to the GLA 250's everyday comfort mission. The Continental PremiumContact 6 is the European-spec equivalent.
For 235/50R19: the Michelin Pilot Sport A/S 4 brings UHP all-season performance appropriate for the GLA 250's sporty pretensions without sacrificing too much comfort. The Continental ExtremeContact DWS06+ is the value alternative.

Best Performance Tires for AMG GLA 35 and GLA 45 S
For the AMG GLA 35 (verify your exact factory size — an AMG-specific package, wider than the GLA 250's): the Michelin Pilot Sport 4S is the premium summer tire choice. The Continental SportContact 7 in the same size is a strong alternative.
For the AMG GLA 45 S (verify your exact factory size — a low-profile 20-inch AMG package): Michelin Pilot Sport 4S and Continental SportContact 7 are the leading choices. The low sidewall means pothole impacts transmit directly to the wheels and curb damage risk is high. Urban driving with the AMG 45 S warrants extra wheel and tire attention.
Winter tires are worth considering for AMG GLA owners in areas with genuine winter weather — the 35-profile performance summer tires lose compound grip quickly below 45 degrees Fahrenheit.
Frequently asked
What size tires does the Mercedes GLA use?
GLA 250 standard: 235/55R18. GLA 250 optional (19-inch): 235/50R19. GLA 250 optional (20-inch): 235/45R20. AMG GLA 35 and GLA 45 S use AMG-specific packages that can differ — always verify with your door jamb sticker.
Can you rotate Mercedes GLA tires?
Yes — the GLA uses the same size on all four corners across all trims. Full front-to-rear rotation is possible. Rotate every 5,000 to 7,500 miles.
What are the best tires for the Mercedes GLA 250?
Michelin Pilot Sport A/S 4 in 235/55R18 or 235/50R19 for a balance of performance and all-season usability. Michelin Primacy Tour A/S for comfort priority. Continental ExtremeContact DWS06+ for value-tier UHP all-season performance.
Does the Mercedes GLA use run-flat tires?
Many GLA trims ship with extended mobility (run-flat) tires. Check your tire sidewalls for MOExtended or similar run-flat markings. Run-flat tires cannot be repaired after a puncture and must be replaced. If you want to switch to standard tires, a portable spare kit or roadside assistance subscription should replace the run-flat safety net.
