Doing some google searching on why one would stretch a tire, because it seems idiotic and illogical to me.
Here are some of the points I found:
"cheaper to buy smaller tires than the right size for the rim"
"to fit a rim that will not fit [in the wheel well] with a bigger tire and remain lowered"
"it's required to drift the car"
"if stretching really was a performance improvement why is it that no does it in F1, Grand Am, Le Mans, etc"?
"Leaves the edge of the rim unprotected from curb or pot hole damage"

"I was driving down the rd and had a front wheel separate from the bead of the wheel and screwed my wheel up badly"
Sounds hella economical....

#13 "I've been running stretched tires for years...about 5 now and never had a real issue. My only issue is that i can usually not tell when a tire is under inflated. I've ruined 3 tires by driving on them flat"
There is no issue, other than that little issue of ruining 3 tires. Whats the word? IDIOT!
How many tires have I ruined due to under inflation in nearly 2 decades of driving? Zero.
#3 pretty much sums it up "[stretching] is not sanctioned or recommended by competent authorities in the tire industry"
#14 "ive owned 18 sets of rims always had tire stretch and not once had a tire fail"
18 sets!?!? as in 72 tires?!?!?!?!!!! Looks like they never lasted long enough to fail.
The impression I am getting is these guys are looking for tires that will last weeks or months, I want several years out of 5 tires (im old fashioned I always buy my sets in fives).
