First time we had to use fire to make a tire stretch out.
Stretching 195/45R15s on 9Jx15 BBS RMs.
Didn't work at first, but we got there! (Still not as good as in other videos I have seen, but hey..whatever! It's fun!)
As more and more people cry about handling and whatever when it comes to stretched tires:
These wheels will be going on a stanced out 1986 Scirocco 16V weekend cruiser.
It's meant to look good in the first place, handling just comes second.
Stretching tires that much will make the handling in fast corners worse...normal driving you won't notice any difference though.
On my MKIII GTI, I run 195/40s on 9" wide rims for daily use and meetings, while I run 215/35s on 9" wide rims for track use (see my onboard videos on the Nürbrugring).
215s will just stretch slightly on 9", stiffening the sidewall up only a little, giving you a more direct steering, while still allowing fast cornering.
In combination with harder rubber bushings, more stiff suspension setup and unbiall top mounts, etc.etc. this results in an almost GoKart like, very direct handling...sure not the fastest setup, but fast and fun enough for me.
