One of the great things about this time of year is the cooler weather and enjoyable time that can be spent outdoors. It's a great time to hitch up the trailer and head out of town for a long weekend and enjoy the changing season . While spending more time driving and on the road, the possibility of experiencing a flat or other tire malfunction is increased. It might even be tempting in a stressful situation to consider putting a trailer tire on your vehicle or vice versa, but that could be risky decision. At the most fundamental level, vehicle tires and trailer tires are built differently --from the sidewalls and tread to the ply and structure. Yes, they are both tires but their functions and the duties that they perform to keep you on the road are different. Truck or car tires are made to be on a lead vehicle. They have thick tread to maintain traction on slippery road and sharp turns. They are also designed to handle the higher speeds of highway driving. Trailer tires, on the other hand, are designed to be on a following vehicle. They have thicker sidewalls to handle debris and other objects that maybe projected at them. The tread is not as thick as car tires and they are not as capable at maintaining traction. In fact they are specifically designed to accommodate the sway that trailers typical experience. Because it is not recommended to drive above 80 miles per hour with a trailer, trailer tires can not handle speeds much greater than 80. If your vehicle and your trailer have the same size tire, it is strongly discouraged that you share tires between them. Both keep you moving down the road smoothly, but they perform different functions that really can't be interchanged. If the price is what is causing you to consider this the Internet is a great place to look for tires. There are a lot of great deals for car tires online . Safety should never be sacrificed for price. Before heading out to enjoy the nice fall weather and start of all the holiday traveling, check all your tires air pressure to make sure that it is at the recommended psi. If you don't already have one, make sure that you have properly inflated spares for both your car and trailer. Doing so will help ensure that you have a fun, safe, and stress free season.
