2006 Porsche Boxster Spare Tire

The Porsche Boxster does not come with a traditional spare tire due to its design and performance-oriented nature. To complement its sporty dynamics and to save weight, the Boxster instead comes with a tire repair kit that includes sealant and a compressor to handle potential punctures or minor tire damage when on the road. The use of a repair kit instead of a spare tire helps to maintain the car ' s weight distribution, enhance its overall performance, and save space. However, should Boxster owners desire a spare, they should note that the recommended tire size for the car is generally 235/35R20 for the front tires and 265/35R20 for the rear, but it drastically varies depending on the exact model and year, thus it is always best to verify with the car's manual or consult with a Porsche dealer or expert.

2006 Porsche Boxster comes with 3 OEM tire size options. 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 Porsche dealership to confirm the correct 2006 Porsche Boxster spare tire size.
