Comparison
245/35 R19 vs 265/35 R19
Stepping from 245/35 R19 to 265/35 R19 keeps the 19-inch wheel but widens the section by 20 mm. This swap moves rolling diameter a touch off the original spec. The wider section adds contact patch and lateral stability, while eating into fender and suspension clearance.
Expect a slight but noticeable shift in indicated speed compared to the original tires. Diameter change stays inside the conservative ±3% safety window — an OEM-safe fitment on most vehicles.
TakeReasonable performance-leaning swap as long as fender and suspension clearance check out.
Quick math: 265/35 R19 is 14.0 mm taller than 245/35 R19, shifting the speedometer by +2.14%.
