for your application you are spot on, lots of people talk about it being unsafe to run stretch etc but i havent seen alot of info saying it is against manufacturer recommendations, adrs yes but not directly from tyre companies.. i could be wrong and never looked that far into it.
but it goes without saying if you application is big power + traction you want maximum grip. if you are happy to slide and want a slammed tough looking car then you go with whats necessary, i havent heard of many people tyres coming off due to the stretch that often.. and im only talking about a 235 on a 10 for example
