Infiniti Q40 Spare Tire
The Infiniti Q40 doesn't come standard with a spare tire, instead, it is equipped with run-flat tires which are designed to resist the effects of deflation when punctured. Essentially allowing you to drive at a reduced speed to a safe location where the tire can be changed. The decision to not include a traditional spare tire is common in many new vehicles due to weight reduction, increased storage, and cost. However, should you decide to purchase a spare tire for Infiniti Q40, you would need one that matches the original tire size, which is commonly 225/55R17. It is always advised to check your specific vehicle model specifications for the accurate spare tire sizing. Also, it's important to note that the Q40 does not come with a dedicated space to store a spare tire, so you may need to consider this when choosing to carry one.
