I was just trying to mess with you (GM stopped calling it a Positrac quite a while back), because even on a "positrac" rear end, using a smaller diameter tire for a short distance won't hurt anything.
I've owned 3 Vettes, so I know just a *little* about them.  |
I've owned 9 Vette's in my time and hang on a Corvette forum where one of it's members is "John Z". John was a Drive Line Engineer back in the 60's and worked under "Zora" on the Corvette.
The spare tire topic came up once and went thru 2-3 pages. Most guys now use radial tires on there Mid-Years..(63-67) Corvettes. The problem is that that a spare radial doesn't fit flush in the spare tire carrier under the car. It hangs down due to it's thickness and in some cases it's diameter.
Someone posted the question about using a tire that was smaller in diameter then what he had on the car. John addressed what I have typed in regaurds to damaging the clutches. In other words...
It's a Bad Idea.
Going a 100 feet or so might be ok, but remember...those clutches get hot fast and will burn up if the axle doesn't lock up.
When John Z talks..... Everyone listens..
