Right I have just braught a nice set of 13x10 weller wheels, now on my xr2 they look the dogs nads but I'm havering slight issues with arch Clarence behind and steering lock in front now I know most people would say go for the 7" or 8" wide ones instead but I really want to use them so does any one know what tyres I could put on them that will be the lowest profile and the most I can stretch on there because I was hoping that the massive stretch will get my lock back and with the low profileness will give me the clearance on the rear

Can any one help?

10 inch wide rims are simply too wide without major bodywork mods, flog them and buy a set of 13x6 and fit 185/60 tyres. It doesn't matter how much you stretch the tyres - dangerous practice anyway - because it,ll be the rim that hits the inner wing, not the tyre.
