I've went through the archive looking for information about what tire sizes are good for 18x8.5 wheels and have gotten all sorts of different sizes. I've recently purchased a set of ACS type III 18x8.5 rims and they recommend 225/40-18 for those wheels. I've read other people who have put much wider tires than those, with most people having at least the 235/40-18 setup. My question is, is the 225/40-18 setup enough? And how will getting, say, the 235/40-18 setup differ? I'm considering going with 235/40-18 tires and would appreciate any comments and advice on this topic. Thanks a lot!!
