255/35/18 on a 10 inch wheel?

Looking at wheel options and seen a set with 8.5 inch front and 10 inch rears - both with an offset of ET20

My MV2's are 225/40/18 (ET47) and 255/35/18 (ET50) - and I know via willitfit.com that they will poke out more than before, but what about the tyre? I have a virtually new set of Goodyear Eagle F1's on that I'd want to transfer, but don't want rubbing or overstretch.

Calculations below...

my go to guide from the LVVTA says a 255/35/R18 will fit on a 10" rim:

can't comment on rubbing, though... nearly 50mm further out seems like a heck of a lot!

the 50mm poke does sound quite excessive, tyres will look just a little stretched but not too bad, id be thinking again though about wheels with better offset if it were me

Thanks both. Yes, the offset of 20 was slightly worrying. Nothing below 35 seemed to be a general rule of thumb that I hard somewhere.
Appreciate the feedback.
