I purchased these replacements for the oem Goodyear LS tires when my Cadillac STS hit 70,000 miles. I drive the STS with alacrity through the pot holed, cracked, cratered, and earthquake-heaved streets and freeways of greater LA, as well as on extended road trips / ski trips throughout the mountainous regions of the western states, and I found the oem LS goodyears to be an appropriately balanced tire for those varied conditions.
Therefore, I was seeking replacement tires having similarly broad and balanced capabilities.
Following a significant amount of research (tire rack & the mfgr websites), I selected the comfort tread goodyears and have been delighted with the results.
As compared to the oem Goodyear LS tires, or the comparable Micheliens, I've noted two elements of notable difference:
1). The comfort treads have slightly slower turn-in response which I attribute to the more flexible sidewalks. While this would be problematic on a sports car, this is a minor issue for a heavy fwd sedan.
2). The comfort treads are able to very effectively attenuate road noise transmission. I ran the oem LS tires at 35 lbs, and am doing the same with the 18 month old (15,000 miles) comfort treads. Upon instalation, I requested the installer to inflate all four tires to 35 lbs cold. However, after 5 minutes on the freeway heading home from the installer, I exited the familiar freeway to check the tire pressures again fully convinced by the remarkedly reduced road noise inside the already very quiet STS that the new tires were under inflated by at least 5 lbs. lo and behold, both my ears and tire gauge we're consistent: the new comfort treads were very effectively reducing noise and ride harshness. Simply amazing.
The STS's favorite cruising speed is 85 mph, which we're able to do for hours at a time on I-15 through southeast Utah in various weather comditioms. Wander and nibble are minimal, so the new comfort tread tires are superb all weather touring tires.
