PLUS 1, 2, ETC.
PLUS ZERO
If you want to leave your wheel diameter the same, you can still change to a wider tire. (Note: You may need a wider wheel as well.) An example is going from a P195/75R14 tire to P215/65R14 tire. What this means is that your tire width will be wider (195 millimetres to 215), your aspect ratio will be smaller (75 to 65) but the wheel diameter stays the same (14 and 14). Why do this? A wider contact patch on the road can mean better grip and handling.
WHAT IS STAGGERING
A staggered fitment is when you put larger wheels on the back of your vehicle than the front. This specification comes from the vehicle’s manufacturer, and is designed to improve performance on vehicles with rear-wheel-drive. A dramatic example of staggering is a drag race car.
VERY IMPORTANT PLUS-SIZING LEGAL:
BFGoodrich Tires does not recommend up-sizing due to safety reasons. If wheel diameter is increased too much, (from 14” to 17”, for example), or if a staggered fitment is used, then your anti-lock brakes, speedometer and stability system may not work properly. Some manufacturers have already tested and approved multiple wheel diameters, so be sure to ask your authorized BFGoodrich Tires dealer on any sizing needs. (To find one close to you, use the Dealer Locator on this web page.)

5 QUESTIONS TO ASK YOUR DEALERS
When it’s time to buy tires, the last thing you want is to feel intimidated. So make sure you do a little homework before you go.

MIXING TIRES
There may come a time when you replace two new tires instead of four. If you decide to go that route, be sure that your new tires are the same size and tire type as your current tires, and that your dealer always installs the new tires on the rear axle of your vehicle (as shown in the pdf below).

ALL ABOUT PERFORMANCE TIRES
If your car is high-performance, doesn’t it make sense to have tires that are just as high-performance? The main benefits of performance tires are higher speed* capability, improved handling and maximum dry road grip. (The negative is lower tread life.) But you need to know that all performance tires aren’t the same, which is why many high performance car owners own multiple sets of tires. (They often switch to all-season or winter tires in the fall and winter for improved winter grip.)View more -
SEASONAL TIRES
Some tires are created with a unique tread for specific weather conditions, while others are built to handle year-round conditions. Some excel in winter, some in rain and some off-road. There are positives and negatives for each tire, so be sure you understand them.View more -
TIRE WEAR AND DAMAGE
How worn is too worn? There are several ways to check for wear without even getting your hands dirty: You can either look for visible, excessive wear, you can perform the Quarter Test to check proper tread depth, or you can check if the tread is worn down to the wear bar indicators (typically located in the circumferential grooves of the tread).View more
