I went to the Bridgestone Ecopias from OEM Goodyear Integrities, rather big RR change.
In my case I saved $25 per tire going to 185 instead of 195, and my load rating was more than sufficient.
I think "small" changes in width & load cap coupled with a better RR tire are where the gains are to be had.
Increasing width significantly in my experience leads to more troubles unless you are overloading a pickup or suburban and need the weight rating as those tires don't seem to "roll" very well as they grow.
We really need the euro RR ratings to be posted on all our tires, would make it much easier to get both the weight rating and RR we want.
