Alaska Tundra Tires for Main Wheels:

We manufacture a magnesium adaptor for your 6 inch Cleveland wheels to convert them to a 10 inch wheel. This allows the use of a variety of 10” rubber, including the 8.50x10 and the 29x11x10. We have a shaved 4 ply version of the 29 inch tire that has a supple tread area with an appropriate amount of stiffness in the sidewall and at a good weight. These both give a significant increase in floatation and tire radius for rolling over larger obstacles and have proven very reliable.

Our main competition makes a good tire that fits the 6” wheel. They are quite soft and can potentially take frontal impacts very well with their tall sidewall and light, supple construction. The down sides, besides cost, is that they wear quickly and the sidewall is evidently too soft for side loads such as curved or off camber runways (beaches) or crosswinds. We have heard numerous first hand reports of these undesirable characteristics. The Alaska Tundra tire has a more appropriate rigidity to the sidewall, especially for 2000 lb Gross Weight and up size aircraft, as well as a huge improvement in shock absorption and floatation compared to stock tires or 8.50x6 tires. The competitions smooth tires are also much more expensive to buy initially as well as to replace and We have heard numerous reports from 180/185 and 206 customers that they wear very quickly compared to typical aircraft rubber. If you wear out the rubber or it gets cut or damaged prematurely for example, the 10” inch rubber for Alaska Tundra Tires is much more readily available and far far more affordable. ($500 versus $1500 for 29” tires as an approximate example) The versatility of being able to affordably change between tire sizes with the Alaska Tundra Tire system is a significant benefit as well.
