265/35 R22 vs 295/35 R20
Going from 265/35 R22 to 295/35 R20 is a minus-2 setup that adds sidewall on a smaller 20-inch wheel. This setup swings rolling diameter far enough to feel on the road.
Indicated speed will drift far enough that recalibration is worth considering. The wider section adds contact patch and lateral stability, while eating into fender and suspension clearance. The smaller wheel is also lighter and easier to find affordable winter rubber for. The 3–5% diameter gap puts this in caution territory: doable on many cars, but verify clearance and consider recalibration.
TakePractical direction for winter wheels, chains, or rougher pavement where cushioning matters.
Quick math: 295/35 R20 is 29.8 mm shorter than 265/35 R22, shifting the speedometer by -4.00%.
