I beleive they have the 275/50 in the radial but I did not want to go with the 245/50 for the front so I went with the bias plys. It is my understanding that in the metric sizes the 245/60 and 275/60 are about as close as you can come to the original spec size. That coupled with Unique's recommendation of this size and the experience of others led me to these. I can't begin to descibe how much 'lighter' and nimble the car feels. If I recall correctly BFG told me that the 275/50's I had on the car weighs something like 38 pounds each. With these being in the low 20's (I think) you can just imagine the performance benefit. Once again if I remember correctly, for every pound or tire/wheel weight is equivelant to 100 pounds vehicle weight as far as your brakes are concerned. That coupled with about a 50% increase in the coeficient of friction, you can just imagine the increase in stopping ability. Of course I didn't think about measuring this before hand
But seat of the pants is telling me good things. I my mind, small as it may be

, a tire that stops better is a safer tire. Trade off for the road hazard issue.
Don't know about the white lettering. I am looking at the possibility of painting the big Goodyear on them!
