Ford F-250 Ranger tires

No. 8.75-16.5LT/E and 8.75R16.5LT/E are separate documented designations and should not be merged. Both appear for the 1980 and 1981 Ford F-250 Ranger and both pair with a 16.5x6.75 wheel. Their shared nominal dimensions and wheel size do not establish interchangeability, so retain the complete designation when matching the original fitment.

Yes. Both years document 8.00-16.5LT/D, 8.00-16.5LT/E, 8.75-16.5LT/E, 8.75R16.5LT/E and 9.50-16.5LT/E. The 1980 model also documents 7.50-16LT/D, 7.50-16LT/E and 9.50-16.5LT/D. Comparable configurations can differ too: 4x2 GVWR 6350 has five documented options in 1980 but three in 1981. Verify both the model year and configuration.

A 4x4 designation alone does not determine one Ford F-250 Ranger tire size. For 1981, 4x4 GVWR 6700 documents 8.00-16.5LT/D, 8.75-16.5LT/E and 9.50-16.5LT/E, while 4x4 GVWR 8700 documents only 9.50-16.5LT/E. The 1980 4x4 configurations also vary by GVWR and cab style. Match the full 4x4 configuration and GVWR shown on the year page.

The Ford F-250 Ranger uses several documented LT tire sizes tied to model year, drivetrain, cab style and GVWR. The 1980 options range from 7.50-16LT/D to 9.50-16.5LT/E, while the 1981 model documents five 16.5-inch sizes. For example, the 1981 4x2 GVWR 6350 configuration lists 8.00-16.5LT/D, 8.00-16.5LT/E and 8.75-16.5LT/E. Select the exact year and configuration rather than using one model-wide size.

The documented Ford F-250 Ranger fitments use 16- and 16.5-inch wheels. The 7.50-16LT sizes pair with a 16x6 wheel. The 8.00-16.5LT sizes pair with a 16.5x6 wheel, while the 8.75-16.5LT, 8.75R16.5LT and 9.50-16.5LT sizes pair with a 16.5x6.75 wheel. Wheel diameter alone does not establish fitment; the wheel width, model year and exact truck configuration must also match.

The Ford F-250 Ranger has several tire sizes within the same year because its documented fitments vary by drivetrain, cab style and GVWR. In 1980, 4x2 GVWR 6900 includes 7.50-16LT/D and several 16.5-inch options, while 4x4 Super Cab GVWR 6950 includes five different 16.5-inch designations. The year alone therefore does not identify one correct size; choose the configuration that matches the truck.
