At this point, it has been drilled into your cranium that you need to install your vehicle with some new wheels come the winter season. Nothing is going to be reiterated for this question and, instead, we want to take a look at when you should install them. The sarcastic folks out there will say, “in the winter, duh.” However, in some areas, the fall season can bring with it colder weather, and this is the key. Once the weather outside is consistently under 40 to 45 degrees, you should have them installed. You should not wait for the first snowfall and should be proactive to install them before you ever need to drive with them and make sure they are properly inflated.
Along the same line, once the weather is warmer than 45 degrees consistently, you need to replace them with your summer tires for the reasons that have been documented in this guide.
