The 325/40R13 is an uncommon and highly specialized tire size that is not found on standard production passenger vehicles. This size is occasionally used on custom-built vehicles, certain kart racing applications, or heavily modified show cars with aftermarket wheel setups. If your vehicle requires this size, it was likely fitted during a custom build or significant suspension and wheel modification.
At the budget level, options are extremely limited due to the specialty nature of this size, but some smaller regional or import brands may occasionally offer it at lower price points. Mid-range buyers might explore brands like Maxxis or similar performance-oriented manufacturers that sometimes produce non-standard sizes for custom and racing markets. For premium applications, sourcing from specialty tire suppliers or custom manufacturers who can produce made-to-order tires may be the most reliable route.
Because this is a niche specialty size with very limited availability, seasonal sales and timing strategies that apply to mainstream tire sizes are less relevant here. It is advisable to purchase whenever you find this size in stock, as supply can be inconsistent year-round.
Due to extremely low demand and limited production runs, prices for the 325/40R13 size tend to be higher per unit than comparably sized mainstream tires, and availability can cause prices to vary significantly between suppliers.
