I have 235s stretch on 10" on my 15 for the rear
99% of tyre fitters wouldnt touch it as it's dangerous and if the tyre pops off the bead, you can actually get them into trouble
There's only one tyre place here that does it and that's where i got mine done
235s on 10" is not alot of stretch, doesnt even need any stretching techniques to make the bead seat on the rims, it's that easy
As for your rim of choice, i dont get why you would want to swap your Works equip for Lenso D1R??
As for tyres, any tyres can stretch but some are easier than others... And you need to run more psi on the tyres to keep the tyres from popping off the bead
