Winter, because there's mire heat and pressure in the Summer.
Winter tires have a deep and differing grip pattern on then which is designed to push snow and slush awy from beneath them. Summer tires are more designed for basic wet and warm conditions
The tires build up heat and become softer.
actually bicycle tire or for that matter any kind of tire does lose air, the heat in the summer causes the air in the tires to expand. That's why is not a good idea to fill your tires to the max in the summer time.
There is no such thing as car rims for winter. There are however car tires for winter which are called winter tires. They have a much more agressive tread design that will grip better in snow but they wear faster on dry pavement and are noisey. Some people mount these snow tires on another set of rims and change them out come winter removing their summer tires/rims.
The type of style for wheels and tires depends on what you want to use it for. For summer, tires should be more efficient for the road, but for winter, there should be more traction for ice and snow
Tires leak a little over time, so if you haven't ridden during winter you will need to inflate them in spring to compensate for what's been lost over winter.
There are winter tires that are very good to have if you live in an area with a lot of snow and ice. Winter tires provide more traction and are more flexible than all-season tires, so they give you more control on the road and are more durable in the cold.
Both Winter and Snow tires have a more aggressive tread pattern and are made of a softer rubber that grips better in cold weather. I believe that snow tires have a still more aggressive tread pattern than winter tires.
It is very important to have the correct car tires for the season. There are some car tires that are meant for the summer, with less tread, that promote faster speed and better gas mileage. There are other car tires that are meant for the winter, with deeper tread for gripping the snowy roads. There are even tires that are designed to work well in the water, with special tread that pushes the water from puddles off to the sides of the tires so that the car will not hydroplane and crash. Since all of these are so different, and so adjusted to do exactly what they need to do, it is crucial to have the right tires for the weather that you are driving in. The problem with running a car with summer tires in the winter -- something that many people do to save money, unknowingly putting themselves in a lot of danger -- is that the car tires for the summer do not have deep enough tread patterns to grip in the snow and ice. This can lead to a number of problems, such as your car failing to brake when you depress the brake pedal. The tires will stop as they are supposed to, but they will just slide along over the ice after they have stopped. You car will also be more prone to spinning on the highway, or to losing traction in the slush and plunging off the road. This can easily be fixed by having different car tires for different seasons. It is not so much of a problem to run a car in the summer with winter car tires, at least not in terms of danger to your life. The biggest reason you would not want to do it is that the winter tires are expensive, and you will be wearing them out on the summer roads. This is a waste of the investment, and means also that the winter car tires will not be in their best condition when the winter comes around. Therefore, it is best to have a set of summer car tires and another set of tires for the winter.
It is dangerous to over inflate tires at the end of winter because they could be damaged more easily. Over inflated tires can be damaged going over potholes or leftover debris in the roadways.
