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 several years and since I switched to them I have never had a flat tire caused from anything external. I have had one inner tube failure caused by the a Mr. Tuffy tire liner which I have since removed as they are not needed and do cause flats internally such as I experienced. Before I use 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 33,000 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 … very flat resistant 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 diameter 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 the UK … Merlin Cycles They offer excellent service and free shipping if ordering a minimum of $75. With three or 4 tires that is easy enough to meet the requirement. I used to buy them from a company in Germany … bike-discount.de They are the second cheapest prices I have found. They also offer excellent service. I think a maximum of 4 tires can be ordered at one time for the flat rate shipping charge they have. Even with the shipping charge they have always been much cheaper than prices I have found elsewhere with the exception of Merlin Cycles. With this German source the best price per tire is had by ordering 4 at a time. I have found that the price per tire varies from time to time so sometimes I pay more or less than other times. Early on I paid $37 something apiece. Recently I paid $29.45 apiece. Again, the cost thru Merlin Cycles has been better.
I will readily admit that these tires are probably the most difficult tires to mount that I have ever encountered. However, there is a way which once known and followed make it much simpler. Once you learn how to do this it is fairly easy. Here is a video showing how to do it:
