I tried to look up the weight of those Firestone Firehawk SZ50 runflat tires but they don't seem to be made in those sizes.

P245/45ZR17 89Y Y BW 080489 7.5-9.0 8.0 25.7 9.6 7.4 11.9 10.0 811 504 29 340 AA A

I think they are factory C5 tires.

Hmm. Added those tires, but maybe we can get some clarification on Scott's.
Scott: are you sure those aren't Wide Ovals? They make that tire in those sizes.

Interesting to have the tire weight, subtract it and see how accurate other wheel weight posts are.

If I recall correctly, they discontinued the SZ50's that I have about 2 years ago. The sizes that I gave are correct...but they are not run-flats. The rears are labelled SZ50 EP's, but that's the only change from what I stated before.
Rear knuckle assy with hub - 23.46 lbs.
Toe rod assy - 6.64 lbs.
"C" beam for M6 - 7.86 lbs.
LT1 A/C condenser - 8/44 lbs.
Base '95 Vert rear spring, code "NYR" - 7.30 lbs.
Short "dogbone" - 1.28 lbs.
Long "dogbone" - 1.36 lbs.
Weight saved by using Z28 direct thottle cable - 5.80 lbs.

'89 should be close to this page I saved on my '88.
Mine was 3150 IIRC with A/C but the spare tire and radio/speakers removed. Quarter tank and no driver. I'll reweight it soon now that A/C is gone.

re '88 A/C system (all parts) - 50 lbs, that is all the parts put in a box, even the bolts. A/C compressor, condenser, evaporator, lines, accumulator, bracket, et al.
Also of note the C5 thin spokes are shown at 20 lbs IIRC in the C5 thread but I weighted them several times and keep getting 18 on my bathroom scale. I included the part number in the other weight thread in case weights were compared for a different/same part number. IIRC there were several makers for the wheels and there may be different part numbers with different weights.

You should note the weight by year.
Also you should ask for this to be moved to tech, and made a sticky.
