The main consideration is you must have rims with a 25mm maximum offset,
should be marked on the rim as ET25. Michelin make a really nice 215/60X14 R rated, MXV88 "Energy" tyre. They give it a wider stance, stick like the proverbial to a blanket and grip really well in the wet and bugger all road noise. Treads moderately conservative in appearance, but works. Not sure on the 225's with clearance for suspension components. I'm running 215/60's on 15's and have no problems with clearance to suspension and there's still a heap for guard clearance and no sign of them fouling the suspension. No idea on the US laws, but here in Australia, you can only legally increase your track by 1 inch. Michelin are a "Frog" tyre anyway. If you don't like tyres from the "Land of the Rising Sun" you would be looking at "Continental " to stay loyal to The Fatherland! I don't think the extra 5mm either side will cause you any grief, but check with the tyre Company before you hand over the folding stuff. Just don't bend over in your LederHosen while your there!
