Kumho  Ecsta PS31

Really great tire. The OEM Goodyear tires were awful - poor dry traction, lethal in the wet and noisy.

These Kumho's are really quiet, have great dry traction and are very stable in the wet. The ride is also improved over the OEM tires. I don't have a lot of miles on them but so far I could not be happier given the price/performance tradeoff. Highly recommended and I would purchase them again for sure.

My plan when purchasing these tires was to buy them along with 15" wheels to downsize the OEM wheels on my Fiesta ST, as the OEM 17" wheels required a short sidewall which caused the car to "crash" over bumps. I chose the Kumho tires based on price and reviews (specifically those pertaining to wet weather performance). These tires have been almost exactly what I thought they'd be, a jack of all trades for summer perormance. The Kumho probably doesn't have the highest rating in any one category, but I'd say it's above average in almost all ways. It shines in the wet and has pretty good dry grip, but does give up grip much sooner than the OEM Bridgestone. Overall, I like them and feel that they do it all well with no glaring faults - especially considering the price. I'd recommend them to budget minded shoppers, but probably not to someone who wouldn't mind spending more for higher levels of performance and ultimate grip.

Astonished bythe performance of this tires either on the dry and on wet pavement, before this set I had chinese A1 Antares tiresc that slipped all over the place, had less than 200 miles on 'em, changed them st the tire desler less than 2 weeks after as they felt horrible in general. PS31 were recommended as they are firm tires, more complain to my OEM tire feeling, and wow, I'm amazed, the change was night and day. Tires brake on a breath, corner as good as the OEM Dunlop Sports and have a grip on wet pavemente, so far I' aamazed at this tires, and woul by them again on a hearthbeat.

On my first Autocross with these tires on, I broke my personal best. Some track. Worse conditions than the month before, because rain had washed some sand across some of the turns. I took seconds off my time. The ride is soft, which is great for my back. They are definitely less responsive than the Bridgestone Pole Positions that they replaced. BUT, in actual track lap time, they are faster. Incredible bargain!

For the price, it's a solid tire for road warriors engaging in spirited driving. I have them on my GTI VR6, purchased after a big brake upgraded necessitated larger wheels. They're rather low profile wrapped around my BBS RC wheels, and ride quality suffers, especially with my stiff H&R suspension setup. But the car's not set up for comfort, it's set up for fun, and these tires deliver. Incredibly sticky while blasting through curves well into triple digit speeds on a summer day. Steering is precise and instant. The tires make zero complaint when reaching G limits in a fast, tight curve. Acceptable performance in the rain, but I've had a few sketchy experiences with them suddenly hydroplaning on Highway 680 either way between San Bruno and Daly City during heavy downpours.

Note that these tires do not like sitting. Car was in storage for a while and rarely driven between 2019 and 2024. Some of the tires deformed during this time, and there's a noticeable bump and vibration, especially on my rear right, even though tire pressure was maintained during downtime. This commonly happens though to sitting tires though, and I don't fault the tires for it.

Love these tires! I 've only owned them for two weeks but the difference from the 16" Arizonians I had are astonishing! The grip is great, in wet or dry and the comfort is on point with the Arizonians. The Arizonians are an All-Season passenger tire, built for a comfortable ride and good fuel mileage. The Kumho's are the most comfortable Summer Performance tire I have ever seen! So compliant over bumps and dips but the grip is there when you need it. For my Civic LX, they're the best buy.

Bought the Kumho's for my mk6 Golf TDI on the recommendation of users of a mk6 GTI forum � over the course of 10,000 miles with them, I'm happy with my purchase and they provide fantastic value for the money. They are holding up well tread-wise and are super quiet and comfortable on the highway where I do most of my driving. Make no mistakes though, these tires still handle well when going for a B-road blast through the twisties. My Golf is lowered on H&R sport springs and the Kumho's match the performance well and inspire confidence when going on a spirited drive, although they feel a little softer when compared to my mk5 GTI's tires which are stiffer, but far noisier when cruising; this could also be down to suspension differences/tuning between the two however. For a daily driver summer tire, especially for highway cruising, I'd absolutely recommend these tires.

*** I will update after some miles driven and during the rainy season ***

Pros:
Good looking sidewall
None road noise
Very comfortable
Good price

Cons:
Sidewall too soft
Steering is lazy

I am living in the San Francisco Bay Area, and the road condition is bad. The Kumho PS31 is good everyday driver tire because they are quiet and comfy to ride on.

Handling of the PS31 is actually disappointing because I am switching from Hankook Ventus V2 Concept 2 to them, and I even feel more stable cornering with my old tires since the sidewall is so soft on the PS31. I feel like the car doesn't want to turn when turning in. My old tires are 205/50, and the PS31 are 205/55, and I think it matters. I pumped up the tire pressure a little to get a sharper steering response, and hopefully, it will not affect how the tire wear.

I have the same size (205/55) Kumho KU22 on another car, and the sidewall feels a lot stiffer than the PS31. Also, the KU22 provide the same grip level as the PS31. I will only rate the PS31 a high performance summer tire instead of ultra high performance.

My van is used in HVAC service industry. Always has weight in it and I drive harder than average. I constantly check tire pressures and this is my 3rd set of these tires. Each set has given 40 to 42,000 reliable miles, which is great. Excellent tire and great value.

Great price compared to other high performance Summer tires. Replaced OEM Bridgestone S001 which were going on 8 years old but only 15000 miles. These have more visible tread so hoping wet performance will be better. Tire have higher tread wear rating so expect longer life. I went from 205 to 215 size with no rubbing issues (stock height car). Price was very competitive with the other tires I had on list of choices.

Shipped quickly to local Navarre Firestone installer. They had modern Hunter mounting equipment with no touch tire installation. Appointment was handled on time and was great.

I wouldn't consider this an ultra high performance summer tire, especially considering what the other examples in the class perform like. These tires are very vocal-- lots and lots of squealing when cornering, relatively numb steering response and feedback, and suboptimal wet performance. I was looking for a few qualities when buying this tire as I was readying to trade my BRZ in: I wanted an inexpensive summer tire that performed well, was quiet, and had a high treadwear rating. For the most part, these tires do exactly what I purchased them to do, however I am often just looking for a little bit more performance. I am thrilled with the price of these tires and the treadwear. The poor wet performance and the low limits in the dry (especially the poor steering response) are the main things I am disappointed in with this tire. I am often breaking traction when I don't want to. I have used the Firestone Indy 500s on previous cars and absolutely loved them, however I think I will give the General G-Max RS a try next.
