Acura RDX Spare Tire
The Acura RDX, a popular model in Acura's lineup of luxury SUVs, often prompts questions about its spare tire availability and size - a crucial consideration for drivers aiming to be prepared for roadside emergencies. Traditionally, many RDX models have come equipped with a compact spare tire, also known as a "donut" spare, which is smaller than the vehicle's standard tires to save space and weight. This compact spare tire is typically stored in a dedicated compartment in the vehicle's cargo area or under the trunk floor, depending on the year and configuration of the model. It's important to note that the exact size and availability of the spare tire can vary by model year and trim level. In some instances, particularly in newer models, Acura has opted for a tire repair kit or run-flat tires as alternatives to providing a traditional spare tire, emphasizing advancements in tire technology and a shift towards weight reduction and fuel efficiency. Therefore, owners and prospective buyers of the Acura RDX are advised to check the specifics of their vehicle or intended purchase to understand the spare tire provisions, ensuring they are adequately prepared for any tire-related incidents on the road.
Acura RDX models manufactured from 2007 to 2025 have tires with overall diameter ranging from 28.1" to 29.2", 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 Acura RDX years and trims.
Listed below are compact spare tire sizes that can fit some Acura RDX vehicles based on acceptable tire diameter range of 27.3" to 30.1". Some RDX models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct Acura RDX spare tire size designated by vehicle's manufacturer.
