GMC R1500 Suburban Spare Tire

The GMC R1500 Suburban is often equipped with a full-size spare tire, which is typically stowed away in a designated compartment beneath the vehicle or in the rear cargo area. The size of the spare tire essentially depends on the model year and the original tire size that the vehicle was equipped with at the time of purchase; however, it is generally advisable to use a spare tire that is of the same size and type as the regular tires for the vehicle. The specific size can typically range from P235/75R15 for older models to P265/70R16 for more recent models. Nevertheless, in the absence of a full-size spare, one can also use a compact temporary or "donut" spare tire, which is smaller and meant for temporary use until the regular tire can be repaired or replaced, but the size of this type of spare can vary as well. It is important to note that the usage of the spare tire, regardless full-size or compact temporary, should adhere to the vehicle's manufacturer specifications and guidelines to ensure safety.

GMC R1500 Suburban models manufactured from 1990 to 1991 have tires with overall diameter of 28.9", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific GMC R1500 Suburban years and trims.
