I'm still running the stock 16" size but I put Michelin MXV4 Plus tires on mine. I think they are around $100 a tire but I don't know for sure since I got them at an employee price. They are all season tires but have good performance too.
As far as wheel sizes go, the closest you can get to the stock size in a 17" tire is a 205/50/17. Now the size will vary depending on how wide your rim is but in general the dimensions are a match. This size would give you the same 205mm (8 inches) width of the stock tire and a similar overall diameter of 637mm (25.1 inches).
Of course most people want wider tires so they would probably go with a 215/45/17 or a 225/45/17, both of which are nearly identical to the overall diameter of the stock tire. For those of you who want to know how to calculate this I will post the formula below.
The formula is two basic steps but there is an additional step at the beginning if you want to convert from metric to the american system. We'll use the size listed below for the example:
225 /
45 /
17
The
section width,
225, is in millimeters so you can convert it to inches by dividing it by
25.4. This will give you
8.858 inches.
Next you calculate the
section height by multiplying the
section width by the
aspect ratio percentage. For this tire that would be
8.858 *
.45 which equals
3.9861. Make sure to put a decimal point before the aspect ratio or your calculation will be way off.
Lastly to calculate the
overall tire diameter you multiply the
section height by
2 and then add the
wheel diameter. For this example that would be
3.9861 *
2 = 7.9722 +
17 =
24.9722.
As you can see this tire is very close to the stock diameter also.
