After spending some time with these budget priced performance all seasons, I can finally write something about them. I replaced the set a few months early due to irreparable tire damage. Most of the ride / handling comparisons are against the Michelin Pilot Sport A/S+ tires, which where my previous set and generally well regarded high performance all season.
The Ecsta 4x’s are a great value choice in this tire category (High Performance All Seasons). I say value because they were not meant to outperform the top brands, but to stand alongside at least a few of them. Performance is better than I expected. Grip is plentiful in the dry, and was surefooted enough in the rain (or whatever California considers inclement weather). The treadwear looks to be on track for the mileage. Ride quality is not as good as I thought it would be but certainly not bad.
The Ecsta 4x’s are a great handling tire. Turn in is crisp and grip is plentiful. Ultimate grip is shy of the Michelin Pilot Sport A/S+ that I had on previously, but for the money saved, I won’t knock off too much. I won’t notice it on the street. The sidewalls are very stiff and keep the tire from feeling sloppy. It’s a predictable tire. More on the stiff sidewall later. I have no problems with the tire in the handling department. It does what you ask. Weatherwise, I can’t comment on anything other than rain. They handle rain just fine and feel secure on a wet road.
This is the area I will fault the tire. Ride quality is not as good as the Michelin’s or not great in general. It feels rougher and less refined on imperfect roads. The carcass at times feels like it has a spring to it that translates into a bit of a jiggle. It may be the sidewall stiffness. The ones I purchased were an XL designation tire with a 94W service description. Too much stiffness for the GTI. The XL version is not the one to get. The Michelin’s had stiff sidewalls but the ride did not suffer as much. Overall, not a bad ride from the Kumho’s but not great either. Refinement feels lacking. I initially wrote that the ride quality was better than the Michelin’s but extended time revealed otherwise.
Treadwear was as expected. I replaced them a little before their time due to an irreparable puncture but I was satisfied by the mileage. I accumulated maybe 30,000 miles on them. I estimate that they could have lasted another 10k miles, but previous alignment issues left the wear uneven (not the tires fault) and at this point in the tires life it made sense to replace the set. If they hit 40,000 miles, I consider that satisfactory.
The mold that was used to make my particular set suffered from a weird line that ran across the tread. It looked like a crack but was limited to the surface. I didn’t consider it an issue as long as it didn’t get larger. I’ve seen other Kumho Ecsta 4x’s with this mold line/crack. I put a decent amount of miles into the tires and the crack was not an issue but it gives me pause about the quality control. It certainly added some road noise if anything. I looked at the lines during a recent tire rotation and they looked a little bigger larger. They didn’t cause any issues but it’s something that I would rather not have to worry about. It factored into my decision to replace the set.
I really wanted to like these tires because the performance side was great. Grip was good, handling was good, wear was good. However, ride quality was only so-so and could get jarring on expansion cracks and rougher patches. The tread crack (which was the same on all 4 tires) didn’t give me any issues but certainly didn’t reassure me of the quality of the tires.
My final verdict – The Kumho Ecsta 4x’s are a nice performance value but not as well rounded as Michelin’s offering. The money you save reflects in what you get. Performance is great but the ride quality suffers. More expensive tires provide good performance numbers and also provide good ride characteristics. The Continental DWS’ are an example set of highly regarded performance all seasons that provide a good balance of handling and ride characteristics. Tire Rack surveys show that there is a highly competitive field in the high performance all season market. With more competitors coming out with a better balance of ride and handling, the Ecsta 4x’s may come out lighter on the wallet but you’ll know know what you’re missing from slightly more expensive brands. As much as I wanted to like these tires, I cannot recommend purchasing a set.
