Top Kumho Ecsta PS91 Review

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.

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 83% while driving a BMW 640d (225/45 R17 W) on mostly country roads for 20,000 spirited miles
Had these on for 20,000 miles, and they are now pretty bald! Must admit these grip the road extremely well, i cant complain at all, and wish they did the bigger size for my car! (BMW 640D). On the plus size, even in icy conditions, the grip is extremely good. On the negative side, they don't look particularly special, and because they grip so well, steering at the front becomes very heavy! If they were more widely available, i'd buy them again

Given 68% while driving a BMW 530D M sport (275/40 R18 W) on a combination of roads for 500 spirited miles
Had these fitted to the rear of my Beemer a few weeks ago following the positive reviews. I paid £280 for two (fitted) which is around 60% of the price of two OEM star-rated Pirelli P7s.

They've take a few hundred miles to scrub in, during which time the wet/damp weather grip was truly terrible (even allowing for their newness) and dry weather grip even now is well below what I was expecting. I can feel the car moving around more, even driving at 6/10ths.

On the positive side, feedback is night-and-day better than the Pirellis, and the drop off in grip is progressive, but at surprisingly low speeds.

Truthfully, they feel absolutely 'mid range' - not as bad as budgets, but nowhere near as good as premium tyres. I suppose you get what you pay for, but I don't see these as the under-the-radar performance bargain I was hoping for.

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.
