Some whack advice being tossed around here. Pizza cutters in a monsoon is a huge mistake:
1. Smaller Contact Patch = Higher Contact Pressure
Narrow tires put the truck’s weight over a smaller footprint. While this helps “cut down” into snow or soft terrain, in heavy rain the smaller footprint can’t channel away as much water per rotation, making it easier for the tire to lose grip and ride on top of the water.
2. Less Water Evacuation Capacity
Most hydroplaning resistance comes from tread pattern + channel volume.
A 255-wide tire simply has less tread width to evacuate water than a 275/285-wide tire running the same pattern. At highway speeds, water can build up faster than the narrow tire can push it aside.
3. Higher Ground Pressure = Earlier Lift-Off in Standing Water
Think of it like a water ski: higher pressure means it will “plane” sooner if the tread is overwhelmed. This is why very narrow, high-pressure tires (think compact spare tires) are especially risky in wet conditions.
The OE specs win, moderate, C rated. Although I do agree all you lead foots slow the fck down. Esp at a school zone. I live right by one, trucks agro as f during commute hour
