What's the widest tire...

Well, take a look....they fit.
Yes, they are a bit wide for a 5.5.
I really wanted 235s but I got a hell of a deal on the 245s and they have been on there for 8 years with no problem. And they don't rub.

As for the Michelin girl, I have seen much worse...with much less on.

Being an EMT did have it's 'benefits'.
