Beside 225/50/16 what other size can fit a 2002 Mercury Cougar
Your best choice is to use the DiscountTire.com website and use the optional tools available. You can enter your vehicle and the site can be made to do alternate tire sizes.
There are some choices on the left side of the home screen and you can even find out the true road speed versus speedometer readings if you use an optional tire upgrade.
Now there are several ways to change things. Width and sidewall profile both contribute to Revolutions per mile. My Mercury car came with 60 Series tires, changing to a 65 Series of the same width gave me a 5% boost in fuel mileage with a corresponding speedometer error.
You do have some limits, wheel rim width will not work on extreme tire changes. Different width wheels would be needed. You have to consider clearance issues between the tire and frame of the car on turns. Both the inside edges of the tire must clear the frame.
The total tire height reflects 1/2 the distance change below and 1/2 the change above the wheel rim. So ride height would change and wheel opening clearance would change.
You have many choices of tire size. In sidewalls, they make 55, 60, and 65 Series tires. In width, 225,235,245 and P metric. Use the Discount Tire site, maybe the Tirerack site and work with the numbers.
Go to a Tire shop and have then pull a 50 Series, 55 Series, and 60 Series.tire in the same width. You will be able to see for yourself what the numbers mean.
I would feel comfortable saying an upgrade to a 55 Series would be no problem. You should have a Label on the doorjam to show tire sizes and inflation rates.
Please rate my info.
