Would a 1971 Corvette equipped with a Goodyear tire have the designation "DOT" appearing on the outer sidewall? There are no digets following the DOT designation and the tire appears date coded to one month prior to the cars build date. The tires are RWL F70-15s. Thanks.

Re: 1971 Goodyear Tire
I recall 1971 when the "DOT" was introduced but thought it best to run your question by John Kelsey (Kelsey Tire) who reproduces Goodyear tires. Others with better recall may be quicker with a responseTom Russo

DOT started on 1/1/68Comment

Re: 1971 Goodyear Tire
DOT markings started sometime during the 1968 model year. The week/year (last 3 digits in the long code debossing) began during in the first half of 1971 calendar year. The date coding is in the XYZ format where XY is the week and Z is the year. Example 171 = 17th week of 1971.Comment

What's on the opposite side of the tire?Comment

Re: 1971 Goodyear Tire
Mike,
Not sure I understand your question.
There was a thread a couple of weeks ago about debossing on both sides of the tire. Some felt the debossed code was on both sides. I don't
recall that on original tires but I will check when I get a chance.
Does that answer your question.??Comment

Re: 1971 Goodyear Tire
Typically the complete DOT code is only on one side of the tire as I understand.Comment

Re: 1971 Goodyear Tire
In response to Seth's question...John Kelsey wrote:
John's is pointing out that the "DOT" regulation was phased in. Production lines were not stopped immediately and fitted with the code. Rather, as the lines (tire clam shells) went down, than they were upgraded to reflect the new regulations.Not unusual and completely accurate. When the D.O.T. was in its’ formative stages in ’68 we knew something was going to be required in the way of tire registration. We did not know exactly what the format sequence would be at that time. In addition we did not know if the registration alpha numeric continuum was to be on one side wall or both. A brief note here. A given plant system, and their were several, manufacturing tires to be sold in North America could not be placed in the extreme position of complete shutdown of production of tires for highway use due to non-compliance once the regulation became law. As you might imagine. The time period involved for tire manufacturers and D.O.T. to arrive at the uniform TIN sequence we use today as well as its’ location involved many meetings and hearings etc. over a long period of time.
Once the decision was taken. The tire factory systems with active lines containing DOT on both sides were not going to take these molds out of service to weld up the “un-needed” three letters. Think or the internal plant disruption. The factories would simply tap the respective molds for two screws, insert the serial TIN and continue with the manufacturing process. They did not present a negative marketing or legal impact. It just so happens that the Goodyear F70/15 used on the ’68 thru ’72 Corvette used a Goodyear tire with initial work taking place in late ’66 and early ’67. As we all remember, ’67 was to be the ’68 style. Thus do not be surprised should you find a car with and without the DOT engraving. Tom, several details could still be mentioned. This should suffice. If not, just let me know.Tom Russo
