72 Judging tire question

[Gary Schisler]

Good morning to all of you. After reviewing what I saw at Carlisle I went into the 70-72 TIM & JG, but I am still a bit confused. I found five NOS Goodyear Custom Widetreads (not Wide Tread) and it looks like there is a 40% deduction for a original bias tire (non-repro) that is a repalcement tire. Is this correct? The JM mentions "current day service replacement tires" but would the same language apply to a non-current day replacement tire, ie. and NOS tire?

Secondly, I have run into four slightly used, but still very good condition, Firestone Wide Ovals in the correct F70 X 15 bias tires. The only problem is tha they are Redlines. I didn't even know that Firestone made Wide Oval red lines but obviously they are not an original tire. How does the JM deal with a correct tire in all categories except the red line? Not very clear in the book. I have to go see these first but they are less than a 30 minute drive.

If there is a 40% deduct for these tires, then I will keep my radial service replacement tires and take the 50% deduct.

Re: 72 Judging tire question

This is a place where the companion book, NCRS Judging Reference Manual, can shed some light. Bear in mind with the number of permutations of original and service replacement tires (markings, font, placement of font, mfgr & DOT legends, specific tread width/pattern and sidewall specifics), it can be a 'jungle' to both judges and owner as to what's correct and to what extent the 'correctness' extends....

In Section 4, Standard Deduction Guidelines, Rule 3, Tires; there's a table for originality deductions on tires that transcends the JG books cross all divisions of Corvette for judging. It reads:

Deduct 10%--Reproduction OEM brand and size tires with differ from original only because of Federally required DOT markings.

Deduct 20%--Reproduction OEM brand, type and size tires which differ slightly from original in design, construction, material, tread width, tread pattern, white (or colored) wall width, style lettering or pattern.

Deduct 30%--Reproduction OEM brand, type and size tires which differ considerably from original in design, construction, material, tread width, tread pattern, withe (or colored) wall width, style lettering or pattern.

Deduct 40%--Reproduction tires of non-OEM brand having correct size and sidewall specifications.

Deduct 60%--Current-day OEM brand, service-replacement size, bias or radial ply tires or corrent equivalent sizing designation and correct whitewall width.

Deduct 75%--As above, non OEM brand.

Deduct 100%--Orignality and Condition, all other or those with whitewalls mounted inboard.
--------------------------

The use of the term 'Reproduction' might be a little confusing here because there's always the possibility of a tire NOT being a 'reproduction' but being from the era that exhibits identifiable differences in the areas mentioned due to supplier running changes over time and/or model differences (e.g. 'Custom' vs. 'Deluxe Custom').

Re: 72 Judging tire question

Thanks Jack. I have the JRM, just didn't think to look in there. Duh!

As I see it using the JRM, depending on the difference from original, these Redwall Wide Ovals MAY be a 20% or may be a 30% deduction then. I will go over that once I see these tires. Thanks.

Gary -

The latest (sixth) edition of the Judging Reference Manual describes the eight categories of tires and the standard deductions for the seven categories that aren't original; any tire that isn't "original" is either categorized as Reproduction or Current-Day. The Goodyears you describe appear to fall into the 30%-deduction category ("OEM brand, type and size tires which differ considerably from original in design, construction, material, tread width, tread pattern, white [or colored] wall width, style lettering or pattern"); if they were considered to differ only "slightly" instead of "considerably", the deduction would be 20%. There is no category for an NOS (non-DOT) tire that differs from the "original" tire - only for Reproduction tires.

The Firestones you describe may fall into either of the same categories outlined above, depending on how the call is made on the redline feature.

Radials (of correct service replacement size with correct colored wall width) get a 60% deduct for OEM brand, or a 75% deduct for non-OEM brand.

I don't pretend to be an authority on how these judgments would be handled - just repeating what's printed in the Judging Reference Manual. I just got the Judging Reference Manual a couple of months ago from the NCRS Store, and it's the Sixth Edition, copyright 1999; the "Driveline" ad for the Store now shows a Second Printing, Spring 2000, which may be different (I would have thought they'd send me the Spring 2000 Second Printing two months ago, not an old one.. ).
