That's the problem with LRR tires. At best, we might see a 1% improvement in mileage, and we may have to give up safety to get it. The available information is spotty, and testing is questionable, at best. The best information was Consumer Reports, and their testing didn't correlate RR values with their 1-5 scale of worst to best.
