    My 1960 cj5 came with four B.F. Goodrich Trailmaker Silvertown tubeless 9.5-14 tires. Before I got it, the Jeep was last registered in 1985 in the state of California. The tire sidewalls have cracks in some areas. All the tires hold air. My question is what do you think about driving on old bias ply tires? Just short slow trips around 30mph. Mostly want to drive it to a truck show a few miles away. I know that the newest they could be is 1985, but they may be older.

    Ask your Life Insurance carrier, Auto Insurance carrier & State Vehicle Inspector! ;)

    I'm in farm country & rural roads--if I ever chose to use questionable tires I'd give them a controlled torture test, which would give some confidence.

    Life has its risks--you need to decide the unnecessary. I have old tires on my hay wagons.

    Personally i would (and did) drive tires like that on local roads with slow speed limits.

    Probably not a good idea to get on the freeway.

    Caution is good. But IMHO older tires were/are far more durable than recent ones.

    New tires seem to "sun crack" is no time at all. (However this doesn't mean the cords will rot like they did in Model T days when they were made of cotton!)

    I have a number of vehicles/trailers with tires near 50 years old and still holding air. Hell, the spare on my jeep still has the OEM 1956 air in it.

    From my days 07-11 the roads in the western NY that were not highway had a good wide shoulder. I wouldn't go any faster than hi 2nd. Might even find an old implement to drag there or just poke along with hazards on.

    I'm assuming you are looking at something this weekend but you should look for some road wheels.

    The ones that i have on my cj5 have a little dry rot. Nothing major. I drive on them quite often and have never had an issue. Just keep an eye on them and for me personally, i keep them coated in tire wet. 1 for the obvious reasons and 2 to help soften the rubber up as much as possible. Mine was sitting for an unknown amount of time before i bought the Jeep. Long enough to grow moss on the entire body. Either way, its your vehicle and you know it better than any of us. I wouldnt go flying down the interstate in it but just around town, i wouldnt be puckered up too bad.

    You Jeep has 14” rims? Postal wheels?
    I wouldn’t drive on public roads with tires as old as you say they are. If you got into an accident, I wouldn’t want the liability of old tires. Also, If roads are wet, old tires have little to no traction due to hard rubber.
