    P Body with full sized spare

    My DD has a compact spare and I would like to replace with a full spare.
    It appears if I cut off the sheet metal prop, a full spare should drop in.
    Thanks for your thoughts

    Full size fit my Daytona and Omni just fine, are you sure it won't fit?

    I just tried it again with a smaller OD wheel and still won't fit. Thanks for the suggestion, BTW

    Re: P Body with full sized spare

    I removed that piece from mine several years ago to fit a full sized spare, a 185/70-14 fits perfectly. A few short 2x4 blocks wedge in there and hold it solid.

    Re: P Body with full sized spare

    My 90 shadow had a PERFECT condition 15" pumper with tire on it when I bought it used. I believe the old woman who originally bought the car purchased it with the car. I have had a 205/60r15 in there before, but you have to jam it down there. The bottom of the spare tire well had rotted pretty badly even before I picked up the car in about 01. Perhaps that is what gave it the room to fit better than what is being suggested in this thread.

    A 205/50-15 is smaller than a 185/70-14, A 205/50-15 is about 1.5" bigger.

    Re: P Body with full sized spare

    a couple of
    'blocks to wedge it in" isn't good enough the spare must be bolted down for safety

    I've found the LARGE (3x3?) plastic T nut thingy that came in some cars will work just fine as it will fit down into the lug nut hole in the wheel and thread down on the stud for the jack & spare
    (not refering to the small flater T nut (1x2) found in some cars)

    a 205 60 15 will fit a daytona's spare well but a 205 50 15 will NOT fit a charger well

    Re: P Body with full sized spare

    Well the prop is cut out and spot weld are ground flat and a the prep work is not drying.
    My 205 50 15 fits with lots of room, Now I need to look at my wheel inventory to see who goes with me
    Crabs? Pumpers? Turbo Star? Steelie?

    Don't read more into it than what I said. The tire is bolted down, the blocks serve as wheel chocks and keep any movement from occurring as that little prop shelf that is removed serve's in the same manner with the much smaller donut tire.

    Re: P Body with full sized spare

    If a person is in an accident bad enough to dislodge a spare tire from the well and enter the passenger compartment, a spare tire flying around is most likely not something one will have to worry about. As a matter of fact, I doubt an accident of that magnitude in a 30 year old vehicle would leave a person with a care in this world.

    Re: P Body with full sized spare

    Finally dry.....here is a 205 50 15 that fit perfectly using the stock hardware.

    I also tried a 205 60 15 but it was too tight just like cordes mentioned.
    Thanks to everyone for their comments/suggestions

    Re: P Body with full sized spare

    lol... don't be so sure
    stopping from 40-45 mph to 0 in about twenty inches will probably launch the spare if it isn't attached to the trunk floor

    stove in the side of the airostar van that pulled across in front of me about 16-20 inches - the same distance my first blue daytona took to stop
    that did launch the airostar about 30 feet sideways .. the whole van ..

    shortened the passenger front corner of my car about 2 1/2 feet , not counting the 4 inches the pass side frame rail moved back under the pass front feet and seat taking the floor with it ( A lot of stretching of floor pan)
    I caught the van on about a 45* angle as it tried to pull across into a driveway

    an 89 nose with no rebar dosen't make much of a bumper .. but it might work as an air bag if you pump it full of foam first

    .. I heard the nose go pop first .. before the almighty bang .. which was followed by the realization the windshield was "kinda cold" as I hit it with my head ..
    still just glad it wasn't kinda sharp too...
