Using Different Tire Sizes
courtesy of Bob, The Auto Answer Man
I just discovered that my S-15 Jimmy, which I purchased used about six months ago, has a different tire size than what is specified on the certification label. The certification label lists tire size as P205/75R15 and what's on the vehicle is P215/70R15. I understand this to be a wider tire with a lower aspect ratio than that recommended by the certification label. Correct? I'm not sure that a 205 width is good for a high center of gravity vehicle of this type so I would sooner stay with the 215. However, 70 series tires seem too low for a "Blazer-type" vehicle, even though this one is a two wheel drive. What size would you recommend to optimize ride and fuel economy?

If you run through the calculations, there is only a difference of 6 millimeters of total height difference. Not that big of a deal. I also like the wider tires for that car.
