I am truly baffled as to why they would put these tires on that Jeep:

2012 Jeep Grand Cherokee SRT8: New Tires

Go with a Yokohama, it has better ratings and Mercedes was putting these on thier SUV's for a while.

I am not suprised that the Jeep saw a drastic reduction in performance after they put these on.

I was surprised by this "recommendation":

"At the recommendation of Ralph Gilles, the CEO of SRT, I've even started running the Jeep's tires at 28 psi (33 psi is spec) to try to smooth things out, but honestly it hasn't really worked."

This tire would work, correct? And its not a run flat as far as I can see from the spec?

Personally, this would be my preference when I replace my tires:

Parada Spec-X Performance Truck Tires | Yokohama Tire Corp.

Interesting comparisons of the old and new:


Edmunds had a comparo of the 2007 Jeep GC vs the 2008 Audi R8 and they said:

"A 4,722-pound SUV with the same feel of immovable mass as Stonehenge shouldn't hope to challenge the dynamic prowess of the midengine Audi. Yet the Jeep SRT8 cleaves turns with surprising precision. Stiff suspension underpinnings deliver a firm, confident ride with minimal body roll, resulting in a more than respectable 0.84g result on the skid pad and 61.9-mph speed through the slalom"

Vs. the new:

"Surprisingly enough, the Jeep doesn't even fall all over itself during handling tests, pulling 67.2 through the slalom and 0.87g on the skid pad. It put a beating on the 2013 Porsche Cayenne GTS and trounced the 2010 Land Rover Range Rover Sport SC especially in handling."

Big differences there.
