I have run Kumho Solus on a Corsa for several years ,and many miles. They are a good mid range tyre..
Not quite as good as the premium Goodyear Vectors I ran at the same time on my Mk4 Jazz . The Kumho squeal a bit more when making tight turns on a smooth surface (as do many other tyres) but tread wear, comfort ,noise level and general grip in wet, dry and snow/Mud are plenty good enough for 'normal' use.
I was happy driving on Kumho although TBH I will only replace my Goodyears with the same, or similar ,premium brand.
Some will argue that you should not compromise on tyre quality . Premium tyres generally have higher scores in group test etc for grip in wet, dry and snow etc .. But thats not always true. Budget brands can score surprisingly well, and even the best premium brands are seldom the top scoring tyre in every category . Thus you are often driving in conditions where your tyres are not the best possible choice and drive accordingly.
