Tire size for style 69 rims?

[X5-RWK]

I purchased a set of rims style 69, 18 X 8.5 and I want to know what size tire to get to put on them. I am thinking something like 265 60 R18's but I want to be sure. If anyone has a set and can let me know if I am right or what the actual size I should be getting is, that would be great. I will not be getting the rims for about a week and would like to be able to mount the tires right away. Also, if anyone has any suggestions on some all-season tires I should be getting for these, I would greatly appreciate it. There seems to be a lot of choices out there and I have know idea what to get. Thanks
