Latest Group Test Results

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.
    Conditionally Recommended.

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 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.
