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.

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.

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

best tyre for the price, the grip is there dry or wet, very balanced tyre , the wear is average but they are cheap, overall you get a premium tyre for lesss money

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.

Absolutely terrible tyres had them on my 330i lasted 50000 miles I drive sensible & only do 20 miles a day, worst tyre I’ve experienced never again

I had these tyres on now for just over 6 months after swapping out the ES32 ecos that came with my car and quickly noticed a difference on the way back. Steering weight was slightly heavier, more responsive while turning and more steering feedback. While driving hard I haven't heard any tyre squeal and grip is more than enough both in the dry and wet. While cruising around town it's reasonably quiet and comfortable for this class of tyre. Wear seems to be good so far and I can still see the tread's flag decals on the rears. I would definitely buy these again especially considering they are much more affordable than premium brands while having similar performance.

Replaced my Continental run flats with these and the difference was night and day. No tramming, harshness over the slightest bump. Very quiet and comfortable and good value for money. I have covered 18000 miles on the rear and still showing 4.2 mm. Would definitely recommended.

Having had the 245 section tyre on the back of a BMW for around 10,000 miles i finally needed new tyres on the front axle as well. The Rainsport 3's the Kumho PS91 have replaced were regarded as a good tyre and i didn't think anything was wrong with them while they were fitted but now i realise that the Kumho are a FAR SUPERIOR tyre to the Uniroyals.
The car is transformed in both comfort and grip, road feel has increased and the car now feels much lighter on the front axle with the set of four PS91's installed.
The rear tyres appear to be wearing well after 10,000 miles, i'm expecting to get that out of them again so i'll be happy with that.
If you were wondering what tyre to go for next, a set of these are superb in all conditions, even on some pretty shoddy British roads. They handle normal motorway miles very well, spirited driving and pulling out of junctions in a 310hp BMW with 620 NM of torque gives you no problems, highly recommend, hopefully Kumho continue to make these when i need another set.

Both dry and wet grip is very good!
Very good road feedback.
Advantage of its stiff sidewalls is sharp and fast steering, and disadvantage is lower comfort. (Still more comfortable than OE runflat tyres)
Recommended. I will buy again.

My comments for BMW/Mini owners:
If your car has factory-fitted runflat tyres and you are thinking about changing to conventional tyres, then I highly recommend Kumho PS91. Because of its stiff sidewalls, Kumho PS91's steering character is close to factory-fitted runflats. Never change your factory-fitted runflat tyres with convensional tyres with soft sidewalls. Otherwise your BMW/Mini will loose its steering and handling character.
