That is the same height tire. The 225/245 is the width
You're right on the width, but wrong on the height being the same.
Example: 225/50-16.....The first number is the width in millimeters. So 225 mm. The second number is the aspect ratio of the width. That means the sidewall is 50% of the 225 millimeters. Then obviously the last number is the wheel diameter.
So, a 225/50-16" tire is roughly 24.85" in diameter, while the 245/50-16" is roughly 25.64". The sidewall size is about .4" taller on the 245 versus the 225. Also, the circumference is roughly 2.5" more on the 245 versus the 225.
Just a little FYI for you, since you were trying to make Mike look like a dumbass.
Mike, my car, at the summer cruise when I met you, ran [email protected]
, with 10* of timing, on 17" street radial tires with who knows how much air in them, and ALL of the junk in the back of the car. I would imagine your car has to weigh a couple hundred pounds less than mine, but my car has more done to it as far as engine, heads, cam, intake, etc. My car has 3.55's though, versus your 3.73's.
I didn't make enough passes that night to find the sweet spot off the line. I think the best 60ft time I got out of it was 2.16 or so. It would either bog, BAD, or spin, BAD.
Don't know if any of that helps, but I just thought I would post my experience to give you something to compare to. And to point out that Mr. Smartass above wasn't as smart as he thought he was.
