yes im asking for opinions and what you guys have noticed.... might be dumb but here goes.
anyone switched to a 275/40R17? how does it hold up compared to stock size? fill the wheel wells enough? width too much for it? what have you found?

anyone switched to a 255/55R17? seems to add an inch to the tire height, does that bump at all into the well? cuts the gear ratio a bit, howd that work out? worth it?

yes, send opinions, pics, whatever. would you do it again, or would you opt for a different size? and how hard is it to find OPTIONS for tires in your respective sizes? ive found a few for each different size, now im wondering how they even worked? did it look ridiculous? thats always important. did your performance suffer? just as important. anything is helpful. also, when they "recommend" a rim size for that tire size, how stringent are they? ive run 10.5" M.T Claws on my 17x8 truck rims. worked fine. didnt know if it was the same deal with a performance oriented vehicle. any tire lock problems or just plain fallin off? thanks for inputs....
