Arkayne, If you go 19's you wont be able to fit KU36's. They don't make the right size, 18's only. This is not a major issue there other options for tyres in 19's. For a really good gripping tyre in 19 you will be up for decent money, 500+ I'd say. Options I'd consider would be Pirellis, Michelin, Good Year, Yokohama etc Benny
