Are 18 inch tires good for snow?
The taller sidewall of the 18” winter tires, compared to 20” will be better for winter driving in snowy and slippery conditions. Practically useless in 4 inches (10cm) or more snow/slush. Poor performance in icy conditions. Summary: The tires are great in dry conditions and does have good/tolerable performance capabilities on wet roads. These are decent in light snow conditions only.
What is the 3% tire rule?
The 3% rule states that when replacing tires, the new tire’s diameter should not differ from the original by more than 3%. This guideline helps maintain proper vehicle performance, safety system functionality, and speedometer accuracy. As a general rule, you want replacement tires that are within 3 percent of the diameter (height) measurement of the tires originally on your vehicle.
What tire size is best for snow?
For this reason, selecting a skinnier winter tire option that fits on the original wheels and vehicle is the preferable option for wintry weather. Better yet, downsizing wheel diameter when purchasing a winter tire and wheel package can amplify this benefit. The 7 7 rule for tires provides a simple temperature guideline for timing your seasonal tire changes. Install winter tires when daily temperatures drop to 7°C (45°F) or below for seven consecutive days. Remove them in spring after seven straight days above 7°C.Matching the right tires to the right season When the seasonal temperature falls below 7 °C (46 °F), it’s time to switch to winter tires. Winter tires perform well in all cold weather conditions, ranging from snow and ice to wet and cold dry roads.Average Lifespan of Winter Tires Summer tires usually last between 20,000 and 40,000 kilometers, and all-season tires can go from 40,000 to 80,000 kilometers. But winter tires typically only last 30,000 to 50,000 kilometers. This is because they use softer rubber to grip in cold weather, but it wears out faster.Rubber: Winter tires are made with a special rubber compound that stays flexible in temperatures below 45º F. This means those tires can grip the snow and road better. In contrast, all-season tires can become rigid in colder temperatures, reducing grip on the road.
Should tire pressure be higher in winter?
The Proper Tire Pressure for Winter Driving Typically, it is best that your tires are three to five PSI (pounds per square inch) higher than in non-winter months. Because winter tires have a more aggressive tread to keep traction on snow and ice, they can have a slightly reduced responsiveness. Each vehicle has its own specifications for tyre pressure, but most fall between 28 and 36 PSI (pounds per square inch) however this could be greater especially if you carry extra load in your vehicle or run on larger diameter wheels (there is usually another pressure recommendation for these or the placard).No, for most cars a tire pressure of 40 psi is too high. You might find 40 psi suitable for some vehicles, especially if they’re carrying heavier loads or if the manufacturer’s recommendation is close to that figure. However, it’s generally too high for most passenger cars, which usually recommend between 30-35 psi.The recommended tyre pressure for 225/40 R18 tyres can vary slightly based on the manufacturer and vehicle. However, a general guideline is to maintain the pressure within the range of 32 to 35 PSI (pounds per square inch).Recommended tire pressures vary with the size of the car and its tires. Based on normal tire sizes for each segment, small-sized car are usually 30 psi, medium-sized cars are 36 psi, and large cars are 42 psi. Keep in mind that warm tires normally exceed recommended cold tire pressures by 4-6 psi.
What is the 7 7 rule for winter tires?
The rule of thumb is 7-for-7: wait until there are seven consistent days at 7 degrees Celsius. The reverse is also true for transitioning to winter.

Based on the weather: It’s time to install your winter tires when nighttime and early morning temperatures stay at or near 40º F. Yes, it’s okay if daytime temperatures hover in the upper 50s. You won’t ruin your winter tires overnight, but they will wear out faster as temperatures rise.
