2019 Tyre Reviews UHP Summer Tyre Test - 7th of 8 tyres

  • Positive - Very quick on first dry handling lap, with good steering feel and car balance.
  • Negative - Tyre overheated very quickly in both dry and wet handling, which changed the balance to high levels of oversteer. Very poor wet braking. Average levels of comfort.
  • Overall - The Kumho PS91 initially felt like a strong tyre with good steering and balance, but this soon changed as the tyre heated up, resulting in instability and low levels of grip.

Top 3 Kumho Ecsta PS91 Reviews

Given 97% while driving a Vauxhall Astra VXR (245/35 R20 W) on a combination of roads for 3,000 spirited miles
Replaced Pirelli P Zero k1 tyrew with the Kumhos. I am realy happy that i made the change. The tyre is better on dry and wet in lower temperatures that the p zero. The p zero is slightly better in wet on warm days, but the kumho has a little bigger level of grip at dry, and does not need that high temperatures. Allso the tyre is realy good when puahed hard, doesent lose the grip level by heating up, the level ia going higher and higher. Perfect for everyday and fast road curve driving. Not tested on the race track, but it should perform ok for a street tyre. The stif sidewall is allso a good thing, much stiffer than p zero. I can highly recommend that tyre, they car has more overall grip than with p zero. Wear looks also ok for now.

2/3rds of the price of a premium pilot sport comparison and 8-9/10ths of the performance. Provided you're not trying to be Nigel Mansell on the public highways I see no reason to buy any different. A good upgrade from the ku39's.

Given 73% while driving a Mazda 3 MPS (235/40 R18 W) on a combination of roads for 17,000 spirited miles
Very impressed at the overall performance of the tyre and consider it very good value for money.
Confidence inspiring and good feedback.
Only issue would be the wear & tear, which I feel could be better.
Definitely recommended and would buy again.

Given 34% while driving a Audi A6 2.0 TDI (245/40 R18) on a combination of roads for 10,000 spirited miles
At first i was very impressed with the design and the similarities between Michelin PS4 and PS91. Dry grip was very good but that s the only good thing about this tyre. Sidewall - the stiffness is incredible, you can barely fit them on the rims. Confort - it laks confort, you can feel every bump, big or small, terrible. After 2 years of moderate use 8000k km each summer visible cracks between treads appeared, with is very dangerous thing. On wet they are very slippery, i lost control a couple of times. So then i went for Michelin PS4 and Vredestein Ultrac Vorti which i think is the best tire i had ever had on my Audi A6

Given 76% while driving a Porsche BOXSTER 2.7 (225/45 R17) on a combination of roads for 6,000 spirited miles
Boxster 987. Came with these tyres on but one of the rears had a screw in it so replaced both rears about 6000 miles back. grip has been excellent in both wet & dry, but then again, I never push n the wet. Mostly daily driving with occasional fast B-roads, my rears are nearly done after 6000 miles. I'm not sure if that's my driving style or the compound of the rubber. Either way that's a bit dosappointing in terms of wear.

Volkswagen (255/40 R20) on mostly country roads for 10,000 average miles
Initially I was very pleased with these tyres. They handled much better than the pirelli tyres that came on the car and overall made the car much more stable in corners. Fitted to the fronts when the rears were nearly at the end of their life, I have now found myself replacing all 4 at the same time. Well, this would be the case if tyres hadn't split along sidewalls rending them useless.

Given 61% while driving a Audi 2.7 TDi S Line Saloon (255/35 R19) on a combination of roads for 12,000 spirited miles
Seemed like a great value midrange tyre initially, but wore out very quickly. All 4 where put on with in a month of each other and only last 12.000s on the front. Maybe 30% left on rears. , while the fronts needed replacing. So I've replaced them all for Dunlop sportmax GTs. Only £10 more per tyre.

Given 50% while driving a Mazda RX8 (245/35 R18 W) on mostly country roads for 4,000 spirited miles
Good : -great levels of grip in the dry. -great road feed back. Average : -wear (around 8'000km in the rear) Bad : -really not linear at the limits, in the dry and even worse in the wet. Really not a confidence inspiring tyre. When it goes, it goes. -price, for the price in my size you can have goodyear asymmetric5 for cheaper, and michelin ps4 for only a litle bit more money. I personnaly do not recommend this tyre.

Dry grip was good. In general the tyre was comfortable. Wet grip was scary a lot of aquaplaning when I went into any amount of water.

Tyre is good for grip and handling dry or wet on the rear of a red lexus. Wear though is really poor lasted 6k at best and this was not a hard life

Given 61% while driving a BMW 320D M Sport (225/45 R18) on mostly town for 5,000 easy going miles
Will start by saying these tyres wear quickly on heavy cars!! I have a BMW 320d M Sport and I have done 5,000 miles / 8 months on these tyres and they are now 4mm tread left. So I am expecting these tyres to last up to 10,000 miles :-(

Overall these are good tyres for grip both wet and dry and smooth running. Some things they are not good for are very hard sidewalls so you have to pump the type up to around 36psi to get decent roll on them. Also I was not impressed with the fuel eco on them as they are F grade.
