Tyre stretching

hi,can anyone tell me how safe tyre stretching is and how, by the power of greyskull does it work? it looks the business thats for sure,but i have no clue on how it's done……can anyone help out with a few pointers ( loosely translated as ," a step by step set of instructions    )

it is relatively safe, depending on how big a stretch you run.

all it is is fitting a narrower tyre than designed for the rim. the main reason is it will give you arch clearance on a lowered car with wider wheels that otherwise would catch the arches.

when i have done it in the past they have never been massive stretches so was simple enough to do by pulling and pushing the tyre till it would create enough of a seal for the air to pop it into place.

you tube it and you can see other techniques

sounds fairly simple…as everything else with cars,but as always lands up being everything but….

thanks though
