2012 Jeep Grand Cherokee SRT8: Supple Sumitomos
November 02, 2012
So we mounted some new non-run flat tires to make our Jeep ride better, and what do you know, it worked!
Ask anyone who riding in the Jeep for the first time and they'll say it rides like crap. Nothing new there, after all, this is a serious performance machine. Yes, it's a Jeep, and an SUV, but it's a 470-horsepower Jeep SUV. SRT doesn't mess around, so in order to get the performance the engineers wanted they had to crank up the springs and dampers to a point that makes a comfortable ride quality nearly unattainable.
But...to anyone who had seat time before the new tires, e.g. me, there's a definite difference in the ride quality. Yeah, it's still stiff, but the new tires take the edge off the sharp jolts that used to come through the cabin. It's similar to the effect that airing down the original tires had without the loss of performance or wear. Seems like a good move so far.
