How we ranked these tires for the Mercedes-Benz R320

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 R320?
The all-season touring slate above ranks the top options for the 255/50R19 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 R320 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 R320?
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 R320 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 255/50R19 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 R320?
Plus-size and minus-size alternatives within ±3% overall diameter are typically safe per the ETRTO standard. See the 255/50R19 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.
