The Mercedes-Benz GLB is a compact 7-seat luxury SUV — Mercedes' smallest three-row offering. It shares the MFA2 platform with the GLA and A-Class. The GLB 250 and AMG GLB 35 use different wheel sizes. Tire selection should deliver the refinement Mercedes buyers expect with strong all-season performance.
Mercedes-Benz GLB tire sizes
The GLB 250 uses 235/55R18 on the standard 18-inch wheels (235/50R19 and 235/45R20 optional). The AMG GLB 35 uses 255/40R20 on 20-inch AMG wheels (235/50R19 and 255/35R21 also available). Verify on the driver door sticker.

Choosing the right GLB tire for West Georgia
The GLB splits into two personalities, and your tire choice should follow. A base GLB used as a comfortable family runabout is happiest on a refined touring all-season that stays quiet and grips well in the rain, while a sportier AMG version driven with any intent deserves a performance all-season that matches its firmer setup. West Georgia's wet summers make wet braking the number worth chasing, and the mild winters mean a standard all-season covers you nearly all year.
On budget, weigh cost-per-mile rather than the sticker. A premium tire that lasts longer and stops shorter in the wet often works out cheaper over its life than a cut-rate set, and on a Mercedes the refinement gap is noticeable. If you're torn between tiers or unsure which size your trim runs, a local shop can confirm the fitment and match a tire to how you actually drive.
Frequently asked
What tire size does the Mercedes-Benz GLB use?
GLB 250 (18-inch): 235/55R18. AMG GLB 35 (20-inch): 255/40R20. Verify on the driver door sticker.
How much do Mercedes GLB tires cost?
235/55R18: $150 to $230 per tire. 255/40R20: $180 to $280 per tire. A full set on 18-inch installed runs $600 to $920.
How do I choose tires for a Mercedes GLB?
Match the tire to the trim and your driving. The base GLB rewards a quiet, refined touring all-season that keeps the cabin hushed, while the sportier AMG version wants a performance all-season that backs up its sharper suspension. For West Georgia year-round use, prioritize wet grip. A 3PMSF all-weather tire is worth it only if you head to the mountains in winter.
Should I replace all four tires on my GLB at once?
The 4MATIC all-wheel-drive GLB prefers matched tread depths, so replacing all four together is the safe route to avoid stressing the system. Front-wheel-drive versions can be done in pairs, with the newer set on the rear. If one tire fails early and the others are near-new, a single close-matched replacement can work. Have a shop measure the depths first.
Where can I get Mercedes GLB tires installed near me in West Georgia?
Independent shops around Carrollton, Douglasville, and Villa Rica can source and fit GLB tires, though the sportier trim's larger size may need to be ordered in. A shop familiar with European fitments and the all-wheel-drive matched-tread rule is the one you want. We'll connect you with a nearby shop for free.
