    Has anyone thought about using space saver spare rims and tire for trikes?

    I haven't looked at one for a while but I think they're DOT approved tires. Finding DOT tires for narrow tired motorized vehicles that qualify as motorcycles is a major issue, since bicycle tires don't qualify.

    They also have flat tread sections so they have a great contact patch with the road. Motorcycle tires have near hemispherical treads which don't provide a great contact patch for three wheelers.

    Space savers come with steel or metal rims which were meant to hold up a 1 ton to multi-ton vehicles. They're not going to flex when cornering on anything we're likely to use them as primary tires.

    They're rated up to 50mph. A speed motorized bikes are not likely or legally supposed to come close to achieving.

    In college in the late 80s I had a 1980 Datsun 200sx, it had 185/70-14s and had a space saver which I think was 90/170-18. It's been a long time.

    The only problem might be finding a pair of the same size if they're from really old vehicles.

    There are a few fellas who have used space saver wheels and tires on their cycle cars. They seem to have worked out really well. Used with a differential rear end from a garden tractor and they should be great.

    Trouble is finding the old garden tractors with a differentials, and you need 2 to get the long shafts, so have long on both sides. Or you can get this one,and is the same. http://www.northerntool.com/shop/tools/NTESearch?storeId=6970&ipp=24&Ntt=Kart+differential
    With the differential both wheels pull, and when you turn one will slow and other speed up. With stander-ed trike only one wheel pulls, usually the right. When you pedal it pull to the right, and when you brake it pulls to the left. I have a heavy duty Worksman and does that without a motor, i sure wouldn't put a motor on without a differential. Just my experience....Keep in mind the wider the tire the harder to pedal, more contact .......Curt
