We have not done an internal analysis on total savings. I do have some data on the Michelin Defender though...
@ $3.50/gallon (I wish I was only paying that) you can save up to $250/yr.
Keep in mind that these new LRR last quite a bit longer than a typical non LLR tire in the same performance category. For instance a T speed rated Defender warranties for 90K. 90K is a little high, but with proper care, 80K is realistic. Compare that to a Hankook Optimo H727 which warranties for 100K, but will only get you 60K. Even though they are LRR their performance(wet, dry, ice & snow traction) is up to par if not better than the best non-LRR tires in their respective performance category.
Personally, I do think they are worth the investment.
