Anyone know the estimate of the what each tire weights or the difference?

Have you checked with any of the tire manufacturers? I doubt it would be much. One is wider but has less sidewall. When I switched from my 235/50/18's to 275/40/18's I think the 275's weighed just a tad more but I never weighed them for comparison.

It's not that easy. A lot of things influence tire weight including the compounds used and how much steel belting they have. A better question might be what's the difference in weight between a specific brand and type of tire, as well as size.

I.E. BFG KDW 275/40/18 vs BFG KDW 255/54/18

I believe Tire Rack or Discount Tire has tire weights as part of the "specifications" of the tire or you could check the actual tire manufacturers website.
