The 850R or a lowered 850 can take 205/45 or 215/40. You should be able to use 215/45 on a stock ride height 850. As for tire pressure, wait for a Volan owner to respond. <IMG SRC="http://www.swedespeed.com/ubb/wink.gif"> I would guess upper 30s.<P>
Hey,<P>I run 215/45-17 Yokohama AVSi tires at about 38psi. Have same suspension setup as you; Bilsteins, ipd rear overload coils.<BR>Slight rub at full steering lock, never happens during "normal" driving. No rub anywhere else with this setup.<BR>I wouldn't bother with 205/45 tires, too fragile in the sidewall.<P>I'm about to drop my car with H&R Sport Springs, I'll post results here. <P>Good Luck!<BR>Adam<BR>'96 855R<BR>Bilsteins, Supersprint, K&N, Bosch+4, E-code headlamps
i used to run 32 psi on 205-45-17 pzero assym...result? 4 blown tires (albeit city paid for cost after claim). now i run at least 36...usually 38 on bridgstone s-02 pp. i would run anything above 36...too low and u'd have easy blow outs (although i doubt if i had run it over at higher psi it would've made any diff). 38~42 should be good.
oh, and i have bilsteins hd and ipd springs on all four...i'm waiting to get fenders lipped (the 215-45-17 are slightly rubbing up front)...215-40-17 may not be thick enough (or have high enough load rating) for our wagons...
