Contrary to what idiots may tell you, stretched tires is not an LOLOL DRIFTING Y0 mod. It's a legitimate means of preloading your sidewalls slightly so that they are less prone to sidewall rollover during high load cornering. Less natural sidewall flex allows you to run slightly lower tire PSI, giving you the best of both worlds - stiffer sidewalls, and the contact patch compliance of running lower tire PSI. This does not necessarily effect your tire's maximum grip loading, but makes tire breakaway significantly more predictable and linear, allowing you to be much more consistent at your tire's limit of adhesion.
However, truth be told, sidewall stretch is a bandage for a tire whose sidewall is not nearly stiff enough. That is why most professionally set up race cars you see do not stretch tire -- they run properly engineered tires with stiff sidewalls, allowing them to put as much rubber down on the contact patch as possible by running natural widths on wheels (no stretch).
