Tire Size Question

Re: Tire Size Question
Hi Dave,
To keep something turning takes more horsepower the heavier it is,
that's why the drag racers use a thirteen pound aluminum flywheel and
lighter rims and tires. Of course, that flywheel also stores energy,
that will made the stock V6 buick power CJ with it's fifty pound
flywheel easily crawl over rocks that would easily stop a couple of
hundred more horsepower in a 350" Chevy V8. I know taking your hundred
pound girlfriend with you down the drag strip will cost you a tenth of a
second. As far as sprung and unsprung weight, all I know is it makes a
great deal of difference in their ride and cornering ability, like road
racers need independent suspension to win.
God Bless America, ßill O|||||||O

Re: Tire Size Question
When I tossed the stock tires on my 2.5l, I was surprised at just how fast I
could move.
Once I get these 4.88s in, I'm hoping to get back to that point. Not that I
need to be darting everywhere lifted this high... :-)

Re: Tire Size Question
The reason you use a 13 pound flywheel is to allow maximum ACCELERATION
of the engine. The reason for lightweight tires is to allow
