You should address getting ready for winter just like we prepare for a race. First, check your car or truck mechanically. Check the fluid levels. Look for obvious problems and signs of wear. Replace items like belts and hoses according to the schedule in the owner's manual.
Preventive maintenance is better and cheaper than fixing what breaks.
Next, check the tires. Whether it's in turn three on the race track or on a wet, icy road, the tires need to be at their best. Watch for cuts, uneven wear or objects lodged in the tread that can cause a puncture. Tire wear can tell you a lot about your car or truck. If there is uneven wear or cupping, it may indicate a problem with the tire or suspension alignment.
