Where are you based? and do you mean road legal tyres or tyres with 'car like' tread? I guess you're in the UK as you've spelled tyres with a Y.
As for Oil, it's down to personnel preference as much as anything. As long as you have the correct grade that's compatable with wet clutches you'll be fine.
Some people swear by a particular oil. But unless they have tested it against others in identical engines in identical conditions with the only variable being the oil, then they'd never really know if it is any better.
