As far as I am concerned the very best bicycle tire money can buy is the Schwalbe Marathon Plus. I have been using them now for a couple of years and since I switched to them I have never had a flat tire. Before I used to deal with a lot of flats. I joke about these tires being nearly bullet proof and I think they come close. They are indeed quite amazing!

I personally ride a Catrike Trail recumbent tadpole trike. Here is a picture of me on it.

It is a blast to ride and extremely comfortable. Many compare riding a tadpole trike to driving a go cart or sports car as they handle so well. I have ridden this trike over 23,000 miles. Before I bought this trike I made one similar to it although it was made out of mild steel. My Catrike is made out of aluminum.

Over the years I have tried various other Schwalbe tires on my trikes. All of the various types of Schwalbe tires are quite good … among the very best made in the world, but the Marathon Plus out does them all … flatless and long wear. I highly recommend these tires. I run the 20 X 1.75 406 size. They also come in 20 X 1.35 406 as well as larger sizes for those who have a larger size rear wheel. By far the best price I have found is ordering them online from a company in Germany. They offer excellent service. https://www.bike-discount.de/ Even with the shipping charges coming from Germany they are far cheaper than any other source I have found. A maximum of 3 tires can be ordered at one time for the flat rate shipping charge they have. And, of course, the best price per tire is had by ordering three at a time. Otherwise it probably would be as cheap or cheaper to order them elsewhere.

I will readily admit that these tires are probably the most difficult tires to mount that I have ever encountered. However, there are some secrets which once known and followed make it much simpler. Here is a video showing how to do it:
