Kumho make great Motorsport tyres so I would use them on a road car. Going back to the original post the old Michelin ZX's etc would go to the moon and back and still have tread on them. They were quite revolutionary in their time for road holding compared to Dunlop Groundhogs etc.but the breakaway was instant especially in the wet! I still felt the same on Pilots no warning of breakaway. I think it was something to do with steel braced rather than rayon braced radials, plus the hard rubber compound of course. A friend of mine has raced a Triumph TR5 for years and years and uses the traditional Dunlop CR65 cross ply tyres. Low ultimate grip but plenty of breakaway warning and great handling. He says the youngsters he competes against turn up with their modern rubber and fly past him but ultimately end up in the gravel due to instant breakaway.
I found that from progressing from a 4/4 in my youth, forgiving, great handling, drifting etc. to my plus 8, my then dream car, an unforgiving point n squirt car. Nothing to do with the tyres maybe? I still have fond memories of that 1969 4/4, just wish it had more power. 2 litre Zetec on throttle bodies the ultimate maybe? But will probably have to make do with the V8 cruiser for now......
