Hi; the sticker on the inside rear door of my `92 Grand Marquis GS states as follows: standard package- 215-70R15 handling package- 225-70R15 hope this helps!!
For a 1992 Mercury Grand Marquis : From the factory it came with the ( 4.6 liter / 281 cubic inch ) Single Over Head Cam ( SOHC ) V8 engine that was made in Romeo Michigan ( the 8th " character " of the VIN is a " W " )
The 4.6 liter is 281 cubic inches
Which ones?
28 in. diameter tires
15 inch
According to the 1999 Mercury Grand Marquis Owner Guide : # 16 is a ( 20 amp fuse ) for the cigarette lighter
( 20 U.S. gallons )
Should be 4x6. 3x5 is the other size.
MGM's usually understeer, if thrown into a corner too fast. Is your question why yours oversteers instead of under ??? Are front tires the correct size ??

The Mercury Grand Marquis is a nice big car, especially those from 1986, very roomy for those who are tall, with long legs. The original tires size for this vehicle is 215/70-15. There is no other size suggestions for this vehicle.
