opinions on kelly KDA drive tires

I have KDA tires, no problems yet since 737k miles

 

I have 4 KDA tires on rear drive axle, no problems yet since 737k miles. The run better than my older firestone tires. KDA has less rolling resistance than my old firestone.

 

Kelly KDA's have a RR of 145 that is horrible.

Even if you get half the miles out of a Michelin XDA Energy D that has RR of 100, your fuel mileage gain of around 1/2 mpg over 500,000 miles (6 mpg to 6.5 mpg @$4/gal) would save $25,641 in fuel that would buy a few sets of Michelins while you wear out one bad RR set of Kelly KDAs.

I don`t care how long the tire last if the fuel mileage gain is a lot greater savings than the tire life.

Truck Smarter!
Not Harder!

 

This tire doesn't seem to come in 11R24.5 (H load rating)....... Am I missing something ?

 

whats the date code?

because it was sold as "new" to you doesn't mean it wasn't sitting in some warehouse for 5 years.

 

Both tires come in a 11R24.5 size. When was the H load rating spec posted on this thread that is maybe what you missed?

I have special ordered the Michelin XZA steer tire with an H load rating and I am sure if you check with the dealer, they can get them for you in the XDA Energy D.

 

nope, it was a few months old by the DOT number. I have posted pictures of all the info in the past.

we do tires/maintenance for 31 trucks at our yard and get to experience a wide range of tire brands. from ling long, supercargo and other chinese makes all the way to michelins.

 

My KDA' are splitting too. I have a new set. Only 20 days old and chunks are coming off. Same thing happened with my old set of KDAs

 

Hate to tell you, but theres been ALOT of guys that have had the same problem, myself included.

A while back Kelly Springfield actually discontinued the KDA for a period of time. There were many cases with the sidewalls splitting out and the compound was junk. Kelly claimed they took care of the issue, but my tire guy is still getting complaints about them.

 

Yeah, my side walls have bulges on them too. A bought a new set against my better judgment thinking maybe just maybe they'd be better. Not to mention the price was good too. I guess you get what you pay for...
