Go with 235/45 or 245/40 (yes, they will fit).
Also, and this is a little ironic given where I'm typing this, never listen to forums about tires. The people giving reviews are just like you, trying one new tire every few years with no basis for their opinion (ask any of them if they've actually sampled every tire in competition with their own...they will obviously say no). Even if you stick with a single tire manufacturer and just buy their newest design every time, you're going to experience great improvements over your last tire...but is it actually better than the rest of its class? Probably not.
Here's some good testing for you: http://grassrootsmotorsports.com/art...-tires-part-2/
