As ASM said but if your not relaxed when you ride your bike it will make it harder to ride, your tyres are fine. I noticed when I was learning to ride last year when I was tense riding well just didn't work!
If I were you I would find a quite bit of road or an empty car park and patices turnng, leaning the bike, stopping the bike, emergency stop, then go for a ride. Then ride as much as you can.
I'm no expert at all, but its what I would do.
If your anywhere near, north london, herts/bucks or coming this way, I will go out for a ride with you, like I said i'm not an expert as other on here are, but I will ride for hours fun.
Best of luck, but ride your bike and have fun
