2019 Buick Regal TourX Spare Tire
The Buick Regal TourX, being an advanced and luxurious wagon, is designed to offer an enjoyable and secure driving experience. The issue of a spare tire for this vehicle, however, isn't straightforward. The TourX doesn't come with a traditional full-size spare tire or compact spare (also known as a 'doughnut'). Instead, it comes with a tire inflator kit. The kit is intended to temporarily seal punctures and inflate the affected tire, allowing the driver to reach a service station. However, if an owner decides to opt for a spare tire replacement for additional security during long trips or remote travels, it's important to note that the original tire size of the Buick Regal TourX is 235/50R18. Therefore, a spare tire, whether full-size or compact, should be compatible with this size specification.
2019 Buick Regal TourX 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 Buick dealership to confirm the correct 2019 Buick Regal TourX spare tire size.
