    my tire shop advises that they cannot put an internal patch on 12" 5.3-12 tires.

    1) has anyone else encountered this?

    2) has anyone been told that internal patches cannot be put on 13" radial tires? (my tire guy says that they can be internally patched)

    I ask because I am still considering the switch to 13" rims if my side clearances are adequate in practice ( not just in my driveway).

    I have sceen places that will not do it. And then the landscapers/constrution guys that do it all the time. For me i would replace the tire. Not worth it failing.

    $60 to replace the tire would be my choice. Not worth messing around with those small tires.

    12" tires seem to not be worth patching at the cost of labor to patch, and the cost of new tires.

    at the 99% confidence limit, I am moving up to new 13" rims and tires. I sure hope it all fits (discussed in a separate thread)

    For what it is worth, the resistance to fixing 12" tires has more to do with tread width than diameter, although I can't imagine it being easy getting the buffer / grinder into the 12" hole.

    Reason being due to legal liabilities, most companies that patch tires will not perform any repairs from within about 3/4 of an inch from the shoulder of the tire and down the sidewall. I know most of the tiny trailer tires are awfully narrow.

    Many of the small imported cars ran 12" tires in the '70s. They fixed the tires then. Those tires may have been a little wider, but not much.

    Which ones? Most of them were 13's. 12s have always been an odd duck size... I think the Mini and the Honda 600 might have had 12s, but other than those I can't think of any cars running that small of a tire.

    well, IF I can successfully upgrade to 13" radials, I won't care anymore about 12" tires. It will take a couple of weeks to work thru the upgrade:
    1) check fit of wheel spacers, adjust if necessary (now in hand and they fit OK)
    2) check probable fit of 13" radial tires using new 13" rims with +1/2" offset and a cardboard tire "template" (shipped)
    3) get the 13" radials and then truly find out if they fit as I expect
    4) test drive around corners etc and see if I get rubbing on sides of wheelwells

    Good cars for people that can't parallel park. Most were small enough to drive into a parallel parking space, or just get it close then manually put it in.

    My family had a couple of first generation Ford Fiestas. They were great cars. They were nothing to get excited about, they were just simple, dependable transportation. They went great in the snow.

    Any car I could pick up and shove in the trunk of my Malibu is more like it.
