The original size should be printed on the sticker of the driver door pillar.

Stock size is MOST LIKELY 235/75-15. Checking the door pillar, or owners manual should tell ya for sure though.

Don't forget that you can also buy a different gear for the speedo connection in the transmission to adjust for the mileage being off. Much better and cheaper than new wheels and tires.

The 96 uses a programable speedometer odometer module(PSOM). It gets its speed info from the RABS in the rear differential. You can reprogram your speedo to the correct tire size.
