Will someone please tell me what kind of car tire (by name) and size they have successfully used on the front of the trike please? I'm already convinced that this is what I want to do, so I don't need any advice in that area or a discussion of the +'s or -'s that have been bantered about. Just the facts please. What size (car tire nomenclature) and brand name and I do not want a radial. Thanks for your help in advance.............cd
