2018 Nissan GT-R Spare Tire
The Nissan GT-R is known for its advanced and high-performing features, but it's worth noting that its original configuration does not include a traditional spare tire due to its high-performance nature and lack of space due to the design and configuration of the vehicle. Instead of a spare tire, the GT-R comes with a puncture repair kit to temporarily seal minor punctures, allowing the driver to reach a service station or repair shop. However, if a spare tire is necessary, it's recommended to use the same type and size as the original tires. For most GT-R models, the optimal tire size is 255/40ZRF20 for the front wheels, and 285/35ZRF20 for the rear wheels. Having the same size and type of spare tire ensures optimal performance and safety of the vehicle. But, due to the GT-R's unique tire and wheel setup, many owners conduct thorough research or consult with a professional before purchasing an additional spare.
2018 Nissan GT-R comes with 1 OEM tire size option. Select the original equipment the tire size installed on your vehicle to see all spare tires that have roughly the same tire diameter and can be used as a temporary replacement in the event of a flat tire. Remember that load carrying capacity of the spare tire must be the same or higher than the load carrying capacity of the original equipment tires in order to safely support the weight of your vehicle. Refer to vehicle owner's manual or contact Nissan dealership to confirm the correct 2018 Nissan GT-R spare tire size.
