I have had bad experiences with them. Not only was the performance poor relative to similar alternative branded tyres but I suffered multiple failures.
The tyres delaminated 711's which were replaced free of charge no questions asked with 712's. I had two tyres fail the exact same way within the same week.
Before they failed they provided terrible driving experience, tramlined noisy and very very poor wet grip. I had multiple wheel alignments done all of which came back with the alignment at factory specs.
The 712's were better grip wise when knew but quickly wore and became the worst tyres I have ever owned at 10,000km. I got rid of them at that point even though they still had well over 50% tread left.
Daniel, the KU31's are an autocross tyre, a hybrid street-semi slick tyre which is not intended for street use. That being said quite a few people use them for street use as they are basically a slightly harder longer lasting semi slick with more tread cut out of them so they deal with wet conditions somewhat better. They also are intedned to work from cold.
They are perfect for hill climbs and other events with zero warm up time.
The KU31's are the older model and I believe recently replaced with the KU36's. There was a group by of them on supra forums to suit stock supra rims at a very cheap price I think $600 for a full set.
Given the price I was so temped to by a set but I decided not to given my passed experiences with Khumo tyres.
My Dad tryed Khumo's cant recall which model but there UHP tyre as they were recommended highly to him by our local tyre fitters. He was very unhappy with them.
For what it is worth time and time again I have to suggest you just cant go passed Michelin.
I fitted a set of XM1's to the Pulsar the lowest grade tyre they offer to replace Dunlop SP sports and the difference was amazing. The XM1's provided so much more grip and stability in both wet and dry conditions whist being super smooth and quite.
Before you jump on the they are soo expensive band wagon they were $8 to $12 per tyre more than the basic Dunlop Goodyear ect.
When I replace the 712's I fitted the Michelin's again not Pilots or a super expensive version and they were infact cheaper by a few $ per tyre.
Even though they were not the UHP grade they were fair superior in performance.
