Would these tires fit on my 2001 mercury cougar V6?

I currently own P185/65R15 tires on rims from my previous car and im wondering if they would work on my current mercury cougar. The stock size on my cougar is 215/50R16. I used one of the online calculators and the results came to this:



Original tire

Sidewall: 4.23 in

Radius: 12.23 in

Diameter: 24.46 in

Circumf: 76.86 in

Revs/mile: 824.38



New Tire

Sidewall: 4.73 in

Radius: 12.23 in

Diameter: 24.47 in

Circumf: 76.87 in

Revs/mile: 824.25



Speedometer reading with new tire is 0.02% too slow.

When your speedometer is reading 60mph you are actually traveling 60.01mph.



The diffence between the two are very minor and im considering installing my previous car's winter tires

Now im just wondering if im missing anything important, like if the smaller rims can handle the load and etc...Would these tires fit on my 2001 mercury cougar V6?
Those tires may fit in the wheel well, but that's no assurance that they will fit.



The biggest issue would be bolt pattern, the Cougar uses 4 bolt spaced along a 108 mm circle, while other cars probably use a different bolt pattern, for instance the Saturn L200 used 5 bolts spaced along a 110 mm circle.



If your car was a Ford Focus, a Ford Contour, a Mercury Mystique, or another 99-02 Cougar you should be fine.



The next problem is that the V6 cougar came in several styles, most important here are the standard, and the sport model. The sport came with the 6 spoke 16 inch alloy wheels, rear disk brakes, and a larger front rotor (260mm vs 273mm), while the standard had rear drum brakes and the 15 inch 5 spoke alloy wheel and smaller front rotors. The problem is that the stock 15's do not fit over the brake caliper with the larger brake rotor in place. I have heard that some 15" steelies may fit, but alloy wheels are just too thick.



As to should they be able to take it, yes, they should, but only if they fit.Would these tires fit on my 2001 mercury cougar V6?
That's not much of a difference in tire size, and winter tires are always better for winter. 0.01 mph difference at 60 mph is nothing.....your speedo isn't that accurate from the factory!!



The wheels will fit (your car comes with 15", and you've got a set of 16" so they will have no problem) but it's the bolt pattern and back spacing that could be an issue. Check the bolt pattern for your car and the previous car....if they match, you're in luck.
