Cool no probs dude!
Otherwise it would look like a tractor tyre on a 19" rim.
It should have a number to indicate wear on the tyres. It would be around the 250-350 written on the tyre. The higher the number, the long it should theoretically last.
I'm pretty happy with the Falken's i have on the front of my car, they seem to be lasting well. I've heard the Maxxis tyres are alright too though. My old man has them 17's and he seems happy with them. They are a bit of grip too.
