Sidewall roll is not the largest variable in your suspension setup unless you're running 14-15" wheels with really tall sidewalls. A ~40ish series sidewall on a low profile tire for a 17-18" wheel doesn't have much flex. The difference between a fitted low profile tire and a stretched low profile tire is extremely low with regards to tire flex. The predictability you're experiencing is due to the smalelr contact patch being easier to control then the more grippy, wider, proper fitting tire.
Saying something works on the track doesn't make it right. I'm sure you've seen the mythbusters where they cut a car into bits, including the roof, duct tape it together and thrash the shit out of it.
Given the fact that you
can duct tape a car together and have it survive a beating on a track (ie. you
can stretch your tires and have them not pop off or fail) doesn't make it correct or the right way of doing things.........nor the best way.

3) @RotorDad There have got to be a bunch of morons in VA. Out here in Colorado we understand you can't warranty a tire for camber wear and drifting on them. Like responsible people we deal with the consequences of our actions and buy new tires when we need them. It's sad that they've resorted to denying warranties to stretched tire owners. No doubt related to dumbasses doing dumbass things. I'd be curious if there is a real reason behind this or if its just some old dude arguing how they never did it back in the day and technology hasn't changed and nothing has been made better since 1902. (I love these arguments, they remind me of the one I'm having right now.)

Tire recommendations. Rim widths vs. tire widths. Sure, a shop can stretch tires on for you. Sure they can tell you THEY (the shop) might warranty the tire itself from falling off the rim or would help you if there was a problem - but THE TIRE MANUFACTURER doesn't warranty any tire installed on the wrong size rim. Phone any tire maker you wish and ask them, its just not true. The shop might be willing to help you if there's an issue but don't confuse that with the tire company actually warrantying the tire, or reccommending its installed on inappropriate sized wheels.

4) Sounds like you would get a ticket for following too closely. If you're driving at the legally suggested distance you can react to potholes before you hit them.

You know, there's no reason to be an idiot we can all have big boy conversations. We are all human. I'm sure you've hit pot holes. I've hit pot holes. Whoop dee doo. Is a pot hole going to just destroy a rim outright? Depends. It could happen with or without stretched tires. However, you must be able to admit that given physics and a tire's job, if there is rim epxosed -such as with a stretched tire- that there is a higher likelyhood damage can happen due to the rim being more vulnerable then when it is covered by a tire completely........yes?
