So last time I was messing with tires and wheels, which would have been my K5, 16.5 tires were common with lots of sizes. Now I am after tires/wheels for my K30 and found a set of used 16.5 Welds, but there are no freakin' tires available for 16.5 anymore! Most tires don't even have 16.5's anymore and what brands/models do have a VERY limited selection. Has the 16.5 size been hit that hard in the last two years? Are 16.5's now something to stay away from?
