Hey guys, I have a 2008 250AWD and just recently purchased M45 sport rims with an offset of +50 19x8.5 all around. These rims came with 245 40 19 tires and I was wondering if I can run them on the IS250AWD? Thanks

Hey guys I am looking at TommyT Five Axis S5:F Gunmetal
The specs are 19x8.5 & 19x9. Will there be any issues I face with theses rims? Reading on his FS page there seems to be confusion >_<
What tire size to run n what not , will be goin on my 09 AWD :S

I'm planning on getting 19x8.5 wheels for my IS 350 AWD. Do I go with a 225/35/19 or 235/35/19 tire?
I know the 235 is a bit wider and the sidewall would be a bit bigger than the 225, but why do some choose 225 over 235 and vice versa? Is it just personal preference or is there a pro/con between the two?
Thanks!

With the AWD, we can run staggered wheel set ups on our cars. Thus many, if not all, run a 19x8.5 and a 19x10 in the rear (+/- 0.5" on either end). When you do this, you have to make sure the front and rear tire sizes are no more than 1% difference in rolling diameter (or height of the tire on the wheels). By doing so, you will have no risk of damaging your differentials.
With that being said, there's two tire sizes are match the closest:
Option A) 235/35/19 up front and 275/30/19 in the rear
or
Option B) 225/35/19 up front and 265/30/19 in the rear
Keeping this in mind, Option A offers two benefits. It's the closest match meaning the least risk of damaging your differential and for all intents and purposes, it's got a slightly thicker sidewall for better wheel protection and comfort (minor really). But the drawback is the 235/35 front rubs mostly on the driver side when you turn the wheel 80% or more in if you're lowered too much. With the 275/30 rear, you might rub on certain dips if you're lowered too much.
Keep in mind both of these can be remedied relatively easily. The front is merely the fender liner rubbing. You can take a heat gun, heat the area where the tires rub and push it in. For the rear you just have to roll the fenders. Problem fixed for rubbing unless you go reallyyyy low.
Now if you put in 225 and 265, it solves the issue with rubbing even if you don't modify the fenders. And it actually gives you a slightly stretch in tires if you run the common 8.5 front and 10 rear setup. But it's minor.
So it really comes down to preference. Personally I like the 225/265 look but the IS can't be lowered too much so I'm going to use the 235/275 route to fill in the wheel gap and also give that slight bit of protection to the wheels I need since I let my family drive my car.

I'm really scared to run a staggered setup because I'm concerned with what "could" happen. I also don't want the dealership to hassle me for anything since it's brand new and I don't want to affect my warranty in any way. So, that is why I'm heavily leaning toward a non-staggered setup. Although, I really like the look of a staggered setup.
I plan on doing F Sport springs only, so it won't be lowered that much. I'm leaning towards a 235/35/19 to give me a small extra sidewall cushion and I don't think I'll have any rubbing with just F Sport springs. The roads here in Oregon can be a bit nasty,, so I don't want to go too low and I want to protect my rims from pot holes.
Couple questions...
1) What does it mean to roll your fenders?
2) why do people stretch their tires? Just for looks or is there a benefit?
Thanks again!

I am stuck in a pickle. I have 19x10.5's in the rear. And i ordered 265/30's which is the closest diameter,but looks like they will stretch too much. I can either get the 275/30 which is sitll really close in diameter, but is still technically stretching and some shops wont do it. Or i can do 285/30 which is square with the wheel (no stretching) but will be further away from the rolling diameter.
10/10 tire calculator says the fronts are
225/35/19's are 0.92% rolling difference 825 revs/mile
275/30/19's are 2.09% rolling difference 816 revs/mile
285/30/19's are 2.96% rolling difference 808 revs/mile
Is it wiser to do 275 with a very mild stretch and have a closer rolling diameter, or have a flush tire (no stretch) but be further from rolling diameter?
p.s.- I am assuming when it says rolling difference it means compared to stock. (it says 0.92% too slow, and 2.09% too slow) Therefore if i get 225/35 and 275/30 THOSE two only differ by 1.1%? Am i correct in this assumption?

That's perfectly fine. It's a .8% difference in rolling diameter (with the 265-30 being a smaller tire).
I personally don't like the "idea" of having a smaller rear tire but you won't notice it. Although in my opinion, at .8% it's a bit too close for my comfort to the 1% threshold I'd personally prefer to maintain. But it's been proven by a fellow member in Seattle that there's no issues. In fact I believe he ran it in excess of 60k miles or so before selling the car. If it was bad, the differential would have broken or wore out probably within the first 1000 miles
Edit:
Now that I think about it, I believe laobo979 ran a 235/35 front and 265/30 rear as well.

I want to avoid any fender modding so will these work with bc coils.
19 x 8.5 / ET 48 / 5-114
19 x 9.5 / ET 45 / 5-114
And what tire spec suggestions? (its an awd) 225/35/19 up front and 265/30/19?
