Is it possible for me to put either 245 60 15's or 235 60 15's on my V8? If not, what is the widest I could go, or combination at 15, say 245 50, 235 50. I saw some pictures of guys on the list, yet I was told that these sizes, they didn't think, could fit on my car? I'm trying to purchase today. Thanks in advance, team. Lucius
