Shopping for new tires can be a real challenge if you don't know what you are looking for. Fortunately there are lots of resources out there to help you find just the tires and get you back on the road again in no time. One of the most important elements when you are in the market for new tires is the type of tires. It's imperative that you have the right type of tires for road conditions in your area --rain tires, snow tires, or all-weather tires. But before you can choose the type you first need to know what size tires. When you are looking at tires it's good to know how to read tire size but it's not required. If you are looking online many websites tell you what size you need based on the make, model, and year of your vehicle. However, if you are considering purchasing a size different than what is currently on your vehicle understanding tire size can really help. To find out the size of your current tires you can look at your tires sidewall. If you can't find the information on your tire than you can also look in your vehicle's owner's manual. The manual should also give you information about what size tires will work on your vehicle. Calling the dealership can also give recommendations on what size works or don't work. Deciding to change tire size is not something to be done lightly. If the tires are too big they could rub on the wheel well and damage the tires and the vehicle. Also, if they are not adjusted properly it could interfere with your speedometer and odometer. It's always recommended that you take your vehicle in to the dealership or a local tire dealer to get your tires changed so that you know the transition has been made correctly and you can enjoy your new tires.
