Read the Owners Manual....That might help..
1957 Cadillac Eldorado Brougham
Look for a bicycle tire fill tube and tire ca.
Look at the sticker on the drivers door frame.......225, 75 R15
225/75R15's are stock Alternatively 235/75 and 235/70R15 will work.
tAake the freakin tire off and put another one
8 r19.5
Tire change? Depends on the tires. If its just to change a flat, depends on where you live. 10.00 to 15.00 max. If you mean a complete set of tires, It depends on what kind or brand you want.
No
Will a 305 40 22 tire fit under a 91 Fleetwood with adapters
20 inch is least likely to give you troubles 22 inch might give some turning issues. Both will fit just a preference on side wall height and tire comfort.
I believe a 24-70R-19.5 or a 22-70R-19.5.
My 2008 CTS didn't come with a spare tire. Not sure why?
