Nose Tire

The choices depend on what size you have.

I recently went through a very extensive and expensive rebuild of the steering system on my 46 coup to fix a very bad shimmy, and there is a slight shimmy still, the IA said it's most likely the nose tire, and may very well be, as the coop sat for two years and there is a flat spot on the tire, the argument is this, what tire to get, what brand name and what tire works best, name, size and air pressure all come into play and there are more than one that's recommended, but whats the best tire for tye coop? which one works best? Some tires don't require balancing, other do and a lot, so... what works best and who sells it? Any ideas?
