so if i go staggered will it hurt my awd system at all because now that i looked at it i really would love staggered look if i can do it.. :-) out it is ok n went hurt it?.

you can run staggered. you just have to make sure the tires are turning the same amount of turns in a mile basically. that way it doesnt throw off your AWD and mess it up. I mean think about all the Lambo's that are AWD and they run staggered.

Other thing you could do is run different offsets on same width wheel. Put same tire size all the way around. Thats what we did on my wife's AWD.

This is a great idea if you just want the staggered look.

Otherwise, yes you can run staggered wheels, just keep the rolling diameter of the front wheels and the rear wheels as close as possible. I used 1010tire's online tire diameter calculator to figure mine out. The closest I could get was .08% difference from front to rear (235/35-19 front, 275/30-19 rear).

Yes, I am looking at 19x8.5" & 19x9.5" Staggared setup on my 06" IS250 AWD, and a 235/35/19 front tire, with a 265/30/19 rear tire is the best fitment sizes I have found. Only 25.5" in front, and 25.3" in rear. This is overall less than 3% difference from stock size, and only about 1% difference between the front & rear tire size overall heights.

18x9 +20
18x10 +18

This should not be a problem right?

Default Can you guys help

I have a 2007 is250 awd.I bought a set of wheels. Specs are 18x9.5 +35 offset.i am buying some coilovers for my car.what recommendations do you suggest to make fit? I am going to roll my questions and fenders. I have to buy 3 mm spacers.do because wheel barely touches calipers. My question is do I have to buy stretch tires or can I still go with regular size tires and what size can I go with? Or am I going to be forced to buy stretch tire and what size should I buy? Thanks

Your best bet is 245/40 or 235/40 all around. If you're doing the fender work, do 245. You'll be good to go in the rear, but you may need to camber in the front a little bit, and depending on how low you go, you may need to relocate the front bumper tabs.

There's a set of CR Kai's near me at 18x9.5 +33 on all fours. I have an AWD on H&R springs. Any tire recommendations where I won't need to do any fender or liner work?

so are you telling me I have to buy stretch tires then? A friend told me I would need like 275 cause rim is so wide

245/40/18 on a 18x9.5 wheel: You can see that it's a minor stretch.


But go ahead and listen to your friend if you want. Buy 275s. Have fun rubbing the crap out of your fender liners and bumper tabs, and not being able to go low enough to make it look good.

25 pages later and I don't think I found a "definite" answer...sorry if I missed it.

'07 is250 awd
19x8.5 +35 all around
235/35/19
F sport suspension

Would this set up require rolling?
Look flush?
What would my my variance be?

also...regarding the offset

19x8.5 +35
19x8.5 +40
19x8.5 +45

Is the offset related to the camber? ie the closer you are to stock (45 in this case) the more your camber will be in spec?

Thanks for the help...

^^^19x8.5 +40 should be fine without any issues
