I am in need of a replacement rear tyre and have access to a 150 section. Will that fit my standard wheel or be too big????

I've got a 2tk and it's currently fitted with a 150/60/18. I've got to replace it soon and have been looking at a Bridgestone BT014, they also do a less sticky tyre the same size.

Thanks for the reply mate. I'll be getting that one then. It's a Dunlop gpr80.
