Comparison
295/30 R22 vs 295/35 R20
Minus-sizing from 295/30 R22 to 295/35 R20 pairs a smaller 20-inch wheel with more rubber between the rim and road. This tire combination moves rolling diameter a touch off the original spec. Expect a slight but noticeable shift in indicated speed compared to the original tires. The taller sidewall adds cushioning over potholes and rougher roads, with a softer overall ride. Overall the swap sits inside the safe ±3% diameter window, so ABS, traction control and gearing behave normally.
TakeTypical choice for a dedicated winter or off-road setup where extra sidewall pays off.
Quick math: 295/35 R20 is 21.3 mm shorter than 295/30 R22, shifting the speedometer by -2.89%.
