1968 red line tires

[Gregory M.]

My 68 was ordered with F70 15 red lines. The judging manual says Goodyear Speedway are the correct tire but I see an original unrestored 68 spare on ebay with a Firestone wide oval.

Would the Firestones be accepted for flight judging?

Re: 1968 red line tires

As I remember Firestone made a service replacement. NOT ORIGINAL supplier. They made tires for the oil companies [ Shell , Chevronn Atlas etc] also in those days. I sold them in my first Shell station and toured the Firestone plant in San Jose in 1967. Try KELSY TIRE http://www.kelseytire.com for a good OEM replacement reproduction.

I know Kelsey has Goodyear but considerably more than Firestones from Coker. ..does anyone know if Firestones are accepted for flight jufhing?

Direct quote from the JG:

White- or Red-Striped Tires
Striped Goodyear tires have a 5/16-inch-wide stripe one inch from the rim. Firestone tires have a 3/8-inch wide
stripe 1 7/8-inch from the rim. Uniroyal tires have a 5/16-inch-wide stripe 1 3/8 inches from the rim.

Re: 1968 red line tires

I wonder if those measurements are from the outside of the rim edge with tire installed, or distance from the bead of the tire?

Re: 1968 red line tires

Question still remains: will firestone wide ovals result in a deduction when flight judged? My judging guide ( 3rd ed) say s the goodyear speedway is the Red line tire.

Re: 1968 red line tires

Typically, Firestone tires will get a larger deduction than Goodyear tires. The reproduction tread pattern on Firestones is 5-ribs, where the original is 7-ribs. They are easily detectable as replacements.

Goodyear reproductions are a much closer reproduction, with just a few very minor differences.

The DOT date code is detectable on both tires. But, we are not suppose to judge date codes.

OK, so I will bight the bullit and go for the Goodyeer Speedways...so the repops don't have the same 9 rib pattern as original?

Also, I thought the judging guide said that tires after Jan. 68 did have a DOT marking?

Re: 1968 red line tires

Any reproduction tire you buy, whether it be Goodyear or Firestone (Uniroyals are not reproduced for Corvette,) will receive a deduction. A repop Firestone can be spotted from a football field away. A Goodyear is very nicely done but will still receive a deduction.
There is always the option of buying original tires for judging. Of course, it goes without saying, driving on them would be ill advised. If one goes the original tire route, you still have to be careful to find a proper date.

Re: 1968 red line tires

Original tires are an interesting concept, but a bit rich for my blood...I have to start balancing the price of correcting certain items, versus the point deductions to be gained, in order to determine where best to spend my limited resources...where can I find a sample of the judging sheet?

At the top of the page are the words: "ON-LINE PUBLICATIONS"
left click on that and a window will come up with a white box. Below the white box are three columns of hot links. In the far right hand column is "Judging Score sheets". Another left click will get you a page with the years and area of the score sheets. Choose your poison from that page.

To make it easier (but you will never learn how to find it on your own):

Edit add: Judging of tires follows a table in the Standard Deduction Section of "The NCRS Judging Reference Manual." If you are going to pursue NCRS Judging that is a must-have book for your library (along with the appropriate TIM&JG). Those books are available from the NCRS Store. Link to that is ont he top line above.
