I looked at the wrong lines. I didn't know how accurate the info would be since there are too many variables to nail down a consistent weight reference for all wheels.

At widest variation, you have a .5 pound swing from lightest to heaviest. If the late offset phone dial also has a .5 pound swing, some of those wheels could be as much as 16 pounds, over a pound more than the cookie.

Did some weighing of wheels tonight. It was only with a digital bathroom scale with me holding them, so not the most accurate but enough to get a feeling. I re-base lined my own weight after taking a pee in the back yard due to too many Moscow Mules. I hope that doesn't muddy my purely scientific results.

My one set of late offset phone dials in 15x7 came in between 17.2-17.6 pounds. They are mid 87 castings and have been repainted once before I just painted them with some black rattle can.

The one set of early offset cookies I have unmounted came in between 15.2-15.6 pounds. These are just about perfect "barn find" quality I found on ebay with a perfect finish and very little abuse.

Even if my scale if off, I was hoping for a closer margin. Even just by feel I could tell the phonies weighed more.

I've always liked numbers, so I thought I would share the "like". If numbers are not your thing, it's good "put you to sleep" reading.





Assuming I did the math right (a math minor was a gift that came with the requirements for the engineering degree) and keep in mind these are NOT engine torque. What is important to note it the delta between the two sets of data. The first two lines represent the torque required to accelerate wheels that are half a pound different. The next two lines represent the torque required to accelerate a 225/50 R15 and a 205/50 R15 Toyo RR. I had to assume the 225 was 22 pounds and the 205 was 2.2 pounds less. Anyway, you see the differences.

NOTES: I assumed 12 seconds to go from 60 and 100 MPH

Hmmm, looks like I will need to find a set of cookie cutters, especially if they will give me a second per lap advantage There are cookie cutters that fit early offset cars, correct?

Go back to my link with wheel weights, then find the heaviest wheel on the chart. That's the one you get to run next season!
