if one really want to get technical, there should be a sticker on your door jam that has the oem recommended tire size that the whole car was engineered for. they even tell you how much air pressure you need to put in. through millions of dollars of development this was the best compromise the manufacture the engineers came up with all factors considered. so why are so many seeking to alter it? isnt doing so ignoring the engineers advice? if you change the mechanics or deviate from the stock tire wheel size then you are ignoring the engineers advice. :-)

i dont think the pics of the wheels you posted look great but thats only my opinion. for me thats a DM stance or a woo-tang crowd and it wasnt what i was trying to convey. they surely arent the oem size of tires ive listed as an example right?

from my experience in which ive designed wheels for at a major oem. working with the tire and wheel engineers im aware of some of the factors for recommended sizing. there are real limitation is liability or warranty that has nothing to do with safety or performance according to the engineers. depending on the tire having a slightly wider wheel beyond recommended spec to have real world attributes other than appearance like tire response and sharper turn in according to the engineers. remember i said slightly wider within reason.

im in agreement you with effects of excess weight and the rolling diameter gearing alteration. not much have been here mention that the taller tires really compromise the front end geometry when lowering back to stock height and beyond. yes you can feel it.

RUF has 28 lbs boat anchors for wheels on the yellow bird but they were also on their SC and 3.2 cars pushing 230 and 250hp. i find these inexcusable but folks love them.

The 930 or m491 are full of compromises when it comes to wheels by using modified front hub, giant rear spacer and long studs in the rear just to fill up the flare fenders instead of bespoke offset wheels like the rsr. let not mention the additional problems it causes with the excessive scrub radius. but everything is a compromise you take the good with the bad.

yes due diligence... i dont think my mattress is liable to catch fire easier when i cut off the tag or is it?

thank you for the lively debate
