Have to agree with John , I have a ridiculous collection of wheels / tyres
( ask Mr Hubbard ) and still find it difficult to get things right ! Obviously this is mainly due to being a crap driver most of the time but with a control tyre at least you feel that you have a sporting chance of competing with the top boys !
Although that said , the likes of John , Alec , Danny , Ben , Jayson Roper
etc etc could run on rims covered in breadcrumbs and still beat most people ! You'll never get away from the fact that whatever car /tyres they're running they're just better drivers !
I'm all for control tyres but obviously overlook them for RTR and for kids
