Larger tyres?

Hi all, had my wrist slapped for posting on wrong forum!!!! Brand new to this but loving my new project a 2005 defender 90 td5, my question to you all is I have cooper 265/65/18 tyres on boots wheels and would really like to try the cooper stt pros, the only problem is I can only find them in a 275/70/18, would these fit on a standard defender suspension or would I need to modify??

You've posted on the wrong sub forum again

I give up ill try different forum
