Sorry for the newb question.

 

I have a chance to get a set of 4 slicks from a champ car that was used for a test session for a 150 shipped to my house.  Is it worth it, Will my car even be able to warm the tires?  Would they be of any use for me at auto-x's track days.  I don't even know whether it's worth it or not.  

 

They're "240/600R15" I assume he means 240/60 unless I'm missing something with slick tire sizes.  I'd be using them on an 8" wheel.  The car weights around 2300lbs and has around 110 hp.  So I definitely won't be spinning them.

 

Cliff Notes:  Should I get a set of champ car slicks for cheap or just save and buy some R comps 

 

The tire size means they are 240mm (9.45") wide and 600mm (23.62") tall.  A Champ car front tire was 10/25.8R15, width and diameter in inches.  I doubt they would work for solo.  They would not be legal for Stock, Street Prepared or Street Modified.  They should be used with 10" wide wheels.  This tire size was used on the pro Formula Atlantic cars and not Indy or Champ cars.

Waste of time and money. you will never generate enough heat in those tires to get them to their effective operating range.

 

When the American Indy Car series was running (Indy and CART cars, a few seasons old, running on small ovals and road courses) the most effective tires for a number of seasons were Hoosier tires designed for Sprint Cars. Soft sticky rubber that got to operating temp easily, and lasted 100 plus miles.

 Even those would not work on a car that is only 2300 lbs and such low power. And as Lynn mentions, the sizing would not work for you either.
