Comparison
265/35 R22 vs 285/35 R22
On the same 22-inch wheel, 285/35 R22 grows the section width by 20 mm versus 265/35 R22. This alternative fitment shifts overall diameter slightly from OEM. More tread on the ground tends to improve dry grip and stance, with a small fuel-economy and clearance tradeoff.
The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. 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: 285/35 R22 is 14.0 mm taller than 265/35 R22, shifting the speedometer by +1.88%.
