[quote=1speedbike;13023678]Same as with any other car with regular tires. A spare, a goo kit (I personally don't use them because I think it ruins wheels and goo plugs are never as strong as patches), or AAA / All State Roadside Assistance / BMW Assist / etc for an easy tow to a dealership or shop.[quote]
Actually a number of cars do without spares or RFT tires - BMW M models and Porsches come to mind among others which have mobility kits that don't steal the space a spare does.
I carry a compressor + plug kit with both RFTs and non-RFTs and have only gotten two minor punctures over the past 5 years. Inflating the tire en route allowed even the RFT nail to be safely repaired.
