usually, (and I may be wrong) the LRR tires are in the smaller sizes. I guess this means they have a stronger side wall. I do agree with the theory of less side wall deflection but with that info. why aren't they making huge tires (255mm+ width) for the smaller cars. I think you get to a point of diminishing returns with the added weight and frontal area. this may also be the reason that usually the narrower tires have the LRR option over the wider ones.
I have a set of 275mm tires on my truck, they are still 29.1 inches in diameter but they are a very sticky composite and are rated to (I believe) 150+ mph. I think the application determines what selection you have as well.
I don't completely understand all there is to know about the LRR tire thing. I am still learning myself. if there is a better explinations of LRR vs other losses (weight and aero) then I am all ears.
knowledge is power
