thanks Ruedi...always appreciated. (it was your original photos of the tires that got me started on this...it's all your fault)
The wheels in the first photo look pretty nice and if I am seeing things correctly, appear to have a fairly large center dish.
So if that's the case, the bolt-on Daytons may not look too off-the-mark with a 2 or 3 arm spinner on them. That I guess is really the design question, for those of us interested in finding a modern tire in place of the 165hr400. However, I think more mfg info, photos and a real-life experience of someone who's done this are going to be invaluable, if not mandatory before making the investment.
Tire size is an issue; I looked up the respective diameters of the 165-400 and 205 55-16 and there's about a 1 1/2" difference between the two with the 205's being shorter. (Am I correct in understanding that the 165's are about 26.6" diameter?)
Better for getting off the line, but whether speedo error is tolerable?
