If you put tyres into the search function - you're right, it has been asked a million times before!
All I'll say on the subject is; get the
best you can afford.
You can have the best brakes in the world and stability aids, but if your tyres are not up to the job, then they may as well be made from chocolate.
I bought some cheap tyres. They're great in the dry, but not too good in the wet, and I've not even had the courage to try them in the snow & ice.
