tire size for 18x8.5 on a previa??

I need some help guys!! i just bought some rims for my 91 previa. the sizes are 18X8.5 +38 offset all around. what will the best tire size for these? or maybe even pictures?
 
thanks

just test fit em when they come in, check how much clearance you have, and get a tire accordingly....215/35 if its a tight fit.

Is your Egg already dropped?  Or is it still stock height?  This would highly determine how tall of a side wall that you will need to run (also to kill the wheel gap).  Looking at those offsets you should not have any rubbing or clearance issues.  Maybe might even want to run spacers.  As BAHC wrote, do a test fit and you will know where to go from there.

thanks for the replies guys... the egg is currently at stock ride height because i can't find anybody selling springs or coilovers in the US!!!! anyways... i was looking at Mdenoga's egg with the sc430 oem rims on his egg and it looked to be flushed with the fenders. and the size for the sc430 wheels are:
 
* sc430 wheels: 18x8 +45 offset all around
 
* my new wheels: 18x8.5 +38 offset all around
 
so with my offset being 7 digits lower then the sc430 and .5 inches wider what will be the best setup?

well that depends on what size tires mike is running on those sc430 wheels...he also used to run Weds with good fitment, so you might want to PM him about that if he doesn't chime in here.  You're wheels are gonna stick out 13mm more than his sc430's but you also have to consider that he's on air..iirc

im running 19x9 +20 with 215/35 in the front and slammed. coilover max out. so youll be fine with 18

id go with 215 35s

215/35's the only way to roll on 18's

18x8 Lexus SC430 wheels: I was running 225/45R18

19x8.5 Weds Kranze Bazreia 225/35R19

Daily driving.

215/35 for sure
