    I guess he thinks its worth that much because it came off a Mopar??. :Dou: :spank: :spank:

    Polyglas

    For 200 bucks, I'd buy a repro and pocket the extra $800. I think I can sleep at night knowing that the DOT number doesnt match the build date of my car. C'mon guys I think this is getting a tad ridiculous :rant: :rant:

    Wow, people must be taking some good drugs these days. :laugh: Too bad he took it off the rim, it would have still had the air in it from 1971. :Dou:

    I have one of these tires, it is a "JCDL" G60-15 that was the spare tire from a 70 GSX. It also has never been on the ground, and has the stenciled writing on the treads.
    Glad to know what it's worth today.

    Jason,
    I hear ya, but it doesn't really matter. I have the quote NOS, or should I say "NOG" (never on the ground) :laugh: tire for my spare, and 4 nice originals for my 71 GSX.

    2 are either "JCDL" or "JCDM" tires, which are off 70-71 Buicks and 2 are "MBUF" tires. I always wondered where the "MBUF" tires came from, and now I know.

    Of course, if someone gets real crazy, and offers me stupid money for my original tires, I may take the cash and buy a set of repro's.

    I guess I got lucky years ago and bought 2 complete sets of the G60 x 15 P'glas' tires. All are excellent and original, even with the little titties on the rubber. Course the price was right in those days, so I didn't feel too "crazy".

    The never been on the ground P'glas from my conv. is still mounted with air from '69 (early build date car). The colored stripes on the tread still clearly visible. It now resides in the shop and may one day end back up in its original spot in the trunk. I can't imagine driving on those old tires, but mounted for show purposes only would most likely work. Some of those prices are clearly illusions on someones part, or should I say dillusions. Glad I stocked up on parts when things were reasonable.

    tires

    Wow, don't want much, do they. I have 8 of those of 3 diffrent sizes still with the little rubber nibs on them. Maybe I should try to sell them to a Mopar guy :Do No:

    Going back to my Goodyear Tire store days, I think the first two digits of the DOT number is the manufacturing plant of the tire. I dont think the MBUF correlates to Chrysler per se.

    Jason says,
    "I think the first two digits of the DOT number is the manufacturing plant of the tire." Yeah I knew that, but wanted to see what plant the "mopars" were buying them from. That "MB--" tire was from the Goodyear Akron plant, and may have been a replacement tire.

    Two of mine are "MB--" tires, the other 3 are "JC--" tires and are originals from 70-71 Buicks.

    I could actually use 1 more nice tire, 1 of mine has a mark on one of the letters and I would like to find a better one.

    Anyone have a single they would like to sell? I also have one with curb rash on the front, that would be good as a spare, being they were mounted upside down.

    Duane-

    In concours class, is running radials a deduction?? (I'm assuming yes)

    Ken- I would have to assume the car would need to have to have the original equipment tire- ie. Ployglas's or Wide Ovals for concours competition. If your thinking about a set, they're really not that bad to drive on. Ive gotten cought in the rain and was somewhat impressed with the grip for a fiberglass belted tire. And they really do "make" the car. Gives it a vintage look that you just cant get with a radial.

    My question is this- If the repro G60s are perfectly acceptible in concours, why would you spend mega bucks getting the original date coded tires? Bragging rights? Do you get extra points for original tires? I could see spending the extra coin on an original spare maybe. At least the stampings in the tread wont wear out in the trunk :pp Why would you want to risk driving your car on 36 year old rubber? Unless the car is going to be garage jewelry, I wouldnt do 60 mph on them.

    Jason;
    I guess the one polyglas tire I sold you for $50.00 was a steal!
    What was I thinking :Dou:

    Ken asks,
    "In concours class, is running radials a deduction?? (I'm assuming yes)"
    Well the answer is yes and no. Certain size radial tires were available during the 67-69 model years. These sizes are listed in our judging sheets and would require no deductions, however NO 70-72 Buicks came with radials, so if you put radials on your car, it would be a deduction.

    Jason asks,
    "Why would you want to risk driving your car on 36 year old rubber?"
    Well that's a good question. For the Concours/restored classes, as they are currently set up today, there is no reason to use them, as both the repro and original tires are accepted. BUT, there are 3 reasons to use them;

    1. the repros do look different
    2. If you want to put your car into a "Platinum" class judged event, any reproduction part would get a 1/2 point deduction, so original parts are important
    3. Some owners want to be "mega correct" with their cars, and just like them.

    Then there's my reason, I had them, I like them, and it's saving me +$1000 from having to buy tires at this time.
    Duane

    PS. There is one Concours car out there right now with original sneakers, Brads White GSX, and when my car is finished there will be two. I don't think that's too bad company to be with.

    If its any consolation Brian, the bidding only reached 9.99 for that G60. I thought 50.00 bucks was market value. The only reason I bought a used tire is that I didnt want to spend 230.00 for a spare. Plus, I gave it a good home in my 71 GS :pp

    Duane- I can appreciate your answer. The repros are a little pricey arent they? Hmmm...that would make a good tech article. Reproduction vs original tires.

    Speaking of repro tires- Heres a set of H70-15 Firestone Wide Oval white pinstripe tires I picked up over the summer. Found them in the back room of an old Firestone dealer. One of the perks of repairing automotive equipment is poking around old repair shops! The guy had 5 of them. 3 of the 5 still had the stickers! And theyre in remarkable condition. They look like they were made yesterday.

    It should be noted that H70-15s are NOT reproduced and are the optional size for a 68-69 Riviera GS. I think I paid 125.00 for the set.

    You couldn't pay me enough money to put a mid 70s Firestone Tire on my car. I went through hell on my 77Z28 with Firestone 500s that the belts slipped on. Soon after purchase, the car never ran right again and it was all down to the tires. After a couple ditch incidents I sold it. I'd like another shot at it with good tires.

    say what???

    It didn't run right because of the tire's? :confused:

    I remember my uncle telling me how bad the early steel belted radials were. Maybe thats what Mike had on his Z?. Belts would shift all the time. I remember the Firestone 721 fiasco. Tires were blowing left and right. Around the same time, Pintos were found to explode when hit from behind. I remember there being a joke about Pinto's with 721s.

    An excerpt from Wikipedia...

    During the 1970s, the Firestone 500 steel-belted radials were known to separate from the tread, usually at high speeds, due to water seeping under the tread, which caused the belting to rust and the treading to separate. Joan Claybrook, who was the Administrator of the National Highway Traffic Safety Administration (NHTSA) stated before the Transportation Subcommittee United States Senate Committee on Appropriations on September 6, 2000, that, "there was a documented coverup by Firestone of the 500 defect, spurred by the lack of a Firestone replacement tire."

    In March 1978, NHTSA announced publicly a formal investigation into defects of the Firestone 500. Firestone first asserted that only 400,000 tires produced at the Decatur plant were defective. But the NHTSA investigation found that the tread separation defect was a design performance defect affecting all Firestone 500's. After forty-one deaths, and after Firestone initially blamed consumers (improper repairs, rough use, or under-inflation), on October 20, 1978, Firestone then recalled ten million tires.[3][4]
