Though not strictly historically correct, I've long thought a tall, skinny high-performance radial might be a good idea on something like a special or speedster. Generally, the tall radials out there tend to be far too wide for the purpose. The best I could find up to now was a 215/55R18, which is about the same size and proportion as a 4.75x18 in side elevation, but proportionally a bit wide at almost 9" section width. They're not rare, though, and available in up to a V speed rating. Now, just going to show that EVs can be good for something, Bridgestone have brought out a few tall, skinny radials for a forthcoming BMW electric. Unfortunately they are only Q-rated, but they might be safe at well over 99mph carrying 400lbs of lightweight hot rod rather than 1168lbs of batteries. A 175/60R19 is about the same size and shape as a 4.25x19; slightly wider but not much. Its looks won't fool anyone but that isn't really the idea: Try to imagine a Rudge wire wheel in place of the BMW alloy. Here is Bridgestone's blurb: http://www.bridgestone.eu/corporate...bridgestones-ologic-technology-hits-the-road/ I believe a few motorbike sidecar outfit fans have already picked up on this one. FYI ...
This sort of thing? Of course it doesn't look anything like the large-sidewall tyres on '50s hot rods.
