my cabover has always been very good on m.p.g. 6.25-7.00 m.p.g I had the kelly kda lugs at one time. lasted 305,000 mi. had hiwy tread also. they gave me slightly bettter m.p.g. but did not last as long as the kelly's & they appeared to wear more even. I too had one blow a side wall, but was not sure if it was tire defect or something else. I think a good compromise is a all position tire.
some tires will last a long time, some will give a better ride, others wll have less rolling resistance, e.t.c. At one time I had kelly on my steers when it was time to get new ones I asked tire shop about the best steer tire choice. they would not reccommend kelly & offered me b.f. goodrich, but the b.f's cost $150.00 more per tire.
I asked if there is that much of a good difference to justify the higher price. he sais yes. so I took his advice. THE difference was like night & day. the b.f's rode so much better. It was unbelievable. not only did the b.f's last longer but it made my cabover ride almost like a conventional. best extra $$$ I ever spent on steer tires. I used to run i-65 thru ky. and back then if you rode the right lane north or south bound it was real rough. thats where my test ride came in when the b.f's were on.
I also figured this helped a whole lot in areas that I never considered when buying tires. like........ all that former rough riding & bouncing caused my air tank bracket to break, loosened all kinds of things like, lights, wires, bulbs, more things would have to be retightened more often & checked with the kelly tires. ooo... for me it's more than just price, rolling resistance, e.t.c..
