Default Original factory tires

Hello everybody good morning and happy new year. Thank you in advance for your help regarding this question. I have a 2004 Lemans edition and was curious what are the original tires from the factory?

ChatGPT is telling me this Eagle F1 GS EMT for the brand and type of tire. I understand the sizes and have those on record. This is merely for judging consideration.

thank you

That is the correct tire for a non-Z06.

For NCRS 1975 and later:

Deduct 10%---OEM brand and size tires which differ from original only because of markings or other minor differences.

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

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

Deduct 60%---OEM brand that is of the extended mobility type (run flat) on a car that does not have WY5 in the list of RPO’s on its Service Parts Identification Label or OEM brand but tire is not of the extended mobility type (run flat) on a car that does have WY5 in the list of RPO’s on its Service Parts Identification Label.

Deduct 75%---Non-OEM brand, with correct size and lettering.

Deduct 100%---Originality and Condition for incorrect size or those with white letters mounted inboard or outboard.

Default Date coding

Thanks again so much lucky for all the assistance. The question I have is let’s say they’re the correct tires, correct size but the DOT date is incorrect. Does that fall under the 10% deduction category. I can live with 10% versus 100%.
