Just been having another quick look at the Pilot Super Sport tyres and the available sizes.
Although they don't do a 265/35/18 they do offer a 275/35/18 and having done a quick calculation online it seems that this is actually a better match for the 245/40/18s on the front?
I'm not one to normally stray from the OE specified sizes but from what I can work out, 275/35 is -0.4% different in diameter to the front 245/40/18 whereas the OE 265/35 is -1.6%?
Providing there's at least 5mm room for this additional width on the rear arches and/or suspension components, does this not make more sense?
It goes against my usual take on this but if the tyres are better matched size wise, and only ~ 1% between them it could work out well?
seems like PSS is the way to go ..
rears will be fine
211 chassis will easily take 275 at the back. 219 is 255 front and 285 back
