How we ranked these tires for the Mercedes-Benz GLC-63-S

We started with the latest model-year's OEM tire size — 265/45R20 — and filtered our catalog of 22,000+ tires to those offered in that exact size. From there, four parallel rankings:

Best all-season ranks on a weighted score: tire type matches SUV segment, season is "all-season", premium brand bonus (Michelin / Continental / Bridgestone / Pirelli / Goodyear / Nokian).
Best budget ranks on cost-per-warranty-mile — the lower the better. Premium brands get no bonus here.
Best quiet ranks on the EU tire-label dB rating; lower is quieter.
Best winter filters to tires marked 3PMSF severe-snow rated or all-weather class, with a small premium-brand bonus because winter-compound R&D is capital-intensive.

SUV-specific tire models (CrossClimate, CrossContact, Defender LTX) have reinforced sidewalls designed for the chassis mass and often a wider tread for better wet traction at higher curb weight. Use the side-by-side comparison above to weigh the trade-offs against your specific driving — highway-heavy, winter-state, performance-oriented, or budget-constrained.

FAQ

What's the best all-season tire for the Mercedes-Benz GLC-63-S?

The all-season touring slate above ranks the top options for the 265/45R20 OEM size. The leader is selected by matching mercedes-benz-segment fitment, all-season compound class, and premium-brand quality bonus. For most Mercedes-Benz GLC-63-S owners, the all-season touring pick is the best one-tire compromise — long warranty, low noise, reasonable cost per mile.

Should I get a cheaper tire for my Mercedes-Benz GLC-63-S?

The budget slate above ranks tires by cost-per-warranty-mile, ignoring brand premium. The budget pick is genuinely competitive on durability metrics — the trade-off is shorter warranty and slightly higher cabin noise, not actual safety risk. If you drive less than 15,000 miles a year, the budget pick will outlast your replacement window regardless.

Does the Mercedes-Benz GLC-63-S need winter tires?

If you see more than 5 snow days a year or drive at sustained temperatures below 7 °C, yes — winter compounds stay pliable in cold where all-season rubber hardens, which translates directly to shorter braking distances. The winter pick above is 3PMSF severe-snow rated and works for the 265/45R20 OEM fitment. Storage cost is real (4 extra tires somewhere), but the safety margin in winter conditions is substantial.

Can I run a different tire size on my Mercedes-Benz GLC-63-S?

Plus-size and minus-size alternatives within ±3% overall diameter are typically safe per the ETRTO standard. See the 265/45R20 upsize options for the full categorised alternatives table with verdicts.

Where can I buy these tires?

Each tire links to its detail page with live pricing from our online retailer partners. Out-the-door cost (including mount, balance, TPMS service, and disposal) varies by state — use the install cost calculator for a realistic estimate.
