Conservative Rims/Tire Sizing
I've been looking at a set of Advanti A4 Kudos rims lately and thinking about pulling the trigger, however i'm curious about the optimal tire width i should be running.
Currently im on stock 17x8's with the 225 and 245 rubber f/r.
These advanti rims are 18x8 +40 offset, and wheelsnext suggests 225 rubber front and back.
225 doesn't seem very wide for the rears and im worried about any lost performance (granted im driving a IS250 RWD and its not exactly a race car by any means). How wide do you guys think i could go for rubber on the rears without having any issues? 235 or 245? or should i just stick with 225.
these are the rims:
I know they aren't volks or works by any means, but i think they look nice and they fit the budget

I've been looking into this for a few weeks now and have gotten a lot of different information.
The stock 18" wheels for the IS350 are 18x8 and 18x8.5 and they run 225/40/18 and 255/40/18 respectively. The tires are a little fat in the back and you plan on running 18x8 all the way around so I'd say you would be ok with going 245s in the back.
Stock diameters for stock 225/40s and 255/40s are:
Front - 25.08661 in
Rear - 26.0315 in
If you use different than what stock is:
235/40 - 25.40157 in
245/40 - 25.71654 in
You want to be as close as what your stock came to so the speedometer and mpg don't change that much. Once again, I am new to this scene too. This is only what I have found out so far from reading the forums and from TireRack.
Guys, correct if I'm wrong. Thanks.

okay here's the thing you might wanna listen.... first... get a staggered... if you don't wanna compromise ride quality get 18s.. not 17s.. please... and you are firstly not using AWD so you should get staggered... so here's my suggestion.
18x8.5 +30 225/40-18
18x.9.5 +30 265/35-18 if they make it in that size....

lol yeah, i've been through all the wheel threads and i have a good idea for tire sizes on 8.5's and 9.5's at this point... however, it seems like no one is running 18x8's front and back so i don't have anything to reference from.
245 seems like it should be perfectly ok though.

gah... okay here's the thing.... wider rims and tires give you more stability and control.... a little but it affects your driving thats why the OEM 18s are staggered althoough only 0.5" but yeah go with our advice go staggered and you'll never go wrong... +40 offset has got nothing to do with how wide your tires should be... the tire width depends on your clearance and also your rim width... a 8" rim should be using 235/35 tops... 245 is just really too fat.... IMO...
