The 165/45R18 is an uncommon and highly specialized tire size that is not found on mainstream passenger vehicles. It may appear on certain lightweight electric microcars, concept vehicles, or highly modified compact cars where narrow, tall-profile tires on large-diameter wheels are specified. If your vehicle requires this size, consult your owner's manual or a tire specialist to confirm fitment, as availability is extremely limited.
At the budget level, options are nearly nonexistent for this size, so shoppers may need to consider any available brand regardless of price tier. Mid-range and premium manufacturers such as Michelin, Bridgestone, or Continental occasionally produce niche sizes for OEM contracts, but retail availability is not guaranteed. It is strongly recommended to contact tire distributors directly or check specialty importers to source this size from any reputable manufacturer.
Due to the very limited production runs for this size, it is advisable to purchase whenever stock is available rather than waiting for seasonal sales. Holding off for typical spring or fall tire sales may result in finding no inventory at all.
Due to extremely limited demand and production, prices for the 165/45R18 size tend to be disproportionately high relative to more common sizes, and availability can fluctuate significantly with little predictability.
