For those of you who are staggered

[E.Anderson]

What tire size are you running? I'm thinking about getting 19x8.5 and 9.5 rear with

225/35 up front and 235/45 rear

Will that size difference be small enough that it will run fine with quattro?

[schizzy]

it will be fine running staggered set up

[groundround]

I was thinking about doing the same set up but am not sure on the tire sizes to not ruin anything or how the off set sizes work. I am thinking a VMR wheel like the 701 with 9.5 in the back to have that deep concave look to it.

[b7kevin]

My understanding is that running staggered is fine. What effects the AWD system is when you have bigger tires, so in this situation having 35 and 45 would effect the system. Width doesn't matter, its all in the height.

Thats what my understanding was, so I would need a 225/45 up front?

So I am on my stock TI wheels now with ET 32. no if I go with a ET 40 does that mean the center of the wheel is set back more allowing for more lip or concave?

[E.Anderson]

It's the diameter from center of the wheel to edge of the tire i beleive. Offset has nothing to do with it. So running 19's in back and 18's up front will not work.

I am not running 18's up front and 19's in the back. I am thinking 18x8.5 ET 35 front and 18x9.5 rears. Just a bigger ET of 45 (i think or 40) in the rears. I have 8mm spacers in front and 10 in rear

[E.Anderson]

I know, It was just an example. If your tires are the same size 235/45/18 and 225/45/18 (the sidewall height 45 being the magic number or 35 if you wanted) then i'm thinking you're fine.

Hopefully somebody with more knowledge/experience can chime in on this

[b7kevin]

^^^Thats fine just keep the sizes of the tires similar the front number 225,235,245..etc denotes the width of the tire in mm. The center number 35,45...etc is the height of the tire. I would just rock them both with say a 45 or whatever your taste is. I mean your correct its a marginal difference of mm however anything that contribute to premature part failures isn't for. I'd play it safe.

So I want 18's because I want to use the same tire so I don't have to buy new ones 235x40x18 front and rear tires . I want to go with 18x8.5 fronts with ET 35 and 18x9.5 ET 45 rears. There will be a little stretch in the rears just want to make sure this would be safe including the ET of 45 in the rear tires with running 10 mm spacer in the rear to clear everything.

225/35 runs these all around, u need to have the name size tire all around if you have quattro.

[Kubus]

So much wrong in this thread. 35 or 45 is not tire height. It is a percentage of the width

So if you have 235 width and a 35 profile, it will be 35 percent of the 235. You need to match it up so the rolling diameter will be the same

Taking 235 with a 35 profile and a 245 with a 35 profile will not yield the same rolling diameter.

Stop posting nonsense.

[chrislane31]

way too much bad info in here. a 235/45/19 would not even fit. The rear et is higher because the wheels are 9.5" wide. Your stock TI wheels are 18x8 et32. Look up a tire calculator and make sure that the 2 tire sizes are within 3% of the tire diameter to keep the diffs happy.

What the streets wont ever be as fucked up as yours!! prob not haha but the one I live on is about as bad as you can get.

All I was saying is that I am interested in going staggered VMR V01 I believe. I wanted the 18 or 19x 8.5 front and 9.5 rear. What tire size would i need to get but want to go no less than 40 on the thickness EXAMPLE 245/40 to the rears

[Geoffafa]

19s with a 40 series sidewall will not fit the car... end of story.

Ok and this is the kind of thing I am trying to find out.

Why wont it fit?
What will I have to run?

If your eyes are bleeding then don't open this tread it's that simple. I am trying to learn here. If your the wizard then fuckin teach, if not then go smoke a butt and calm down.

[bartles]

within 3% of the tire diameter

How does one calculate this %?

[chrislane31]

Google tire calculator. I think miata.net has one or get the tire overall diameter and divide it be the other tire size and see what the percent difference is.

confusing, do i enter what i want the front to be and the rear to be and then what?

[rowyourown]

also, 1010tire.com has a tire calculator

[audi1234]

I am running:
Front 235/35/19 8.5
Back 265/30/19 9.5

x2

[Brillo]

tire width divided by 25.4 mm per inch times profile (0.35) times 2 (two sidewall heights per diameter) plus 19 inch wheel diameter equals the overall diameter.
[(235 mm/25.4) x 0.35 x 2] + 19 = 25.48 inches
[(265 mm/25.4) x 0.30 x 2] + 19 = 25.26 inches
Conclusion: the diameters are less than 1% different so the differential will never see the difference.

From the top of the thread:
front - 225 by 35 by 19: diameter = 25.20 inches
rear - 235 by 45 by 19: diameter = 27.33 inches Conclusion: 8.4% difference. This will mess up a diffy for sure.

[audib7maniac]

I wud just stay with the same size tire all around just to be safe. And you want tire stretch because you will rub like crazy

[Operator]

Just trying to get all the right info before I make a purchase:

Wheels are -
Front: 19x8.5 offset of 32mm
Rear: 19x9.5 offset of 35mm

Is anything under 1% diameter difference legit? I'm looking at 235/35R19 in the front and 265/30R19 in the rear which is a 0.87% difference. But moving to a 275/30R19 is only a 0.08% difference. I used http://www.1010tires.com/TireSizeCalculator.asp And I'm AWD. Thank you for any assistance.

[Mister W]

u need to have the name size tire all around if you have quattro.

-Rob

Is that a fact? There is so many thread on wheels, but everybody giving their own opinion and you still dont know what is good at the end.
So, can a Quattro be staggered, wider wheels at the back? If yes what size usualy people go, 18x8.5 and 9.5 or bigger?
thanx

No. It's not a fact. It's the opposite of that - it's just plain wrong. It's been stated several times in this thread already, as well as dozens of others on the subject:

It's fine to run a staggered setup with Quattro as long as the ROLLING DIAMETER of the two tire sizes are within 3% of each other.

Thank you for clearing it up. And btw , what size would you recommend in 18" , staggered wheels and tires, offset flush as possible without spacers?

[tankdeer]

That would depend on the width of the wheels. ET is relative to width. For instance ET 35 on an 8 inch wheel is not the same as ET 35 on a 10 inch wheel. Post your question with specifics about the wheels you're interested in in the FTWLTBDWICTW thread in the chatterbox.

[E.Anderson]

Fronts are 19x8.5 rears 19x9.5. with that much stretch 225/35 and 235/45 should be less than 8%...right?

[tankdeer]

Yes, that's under 8%. But for Quattro you need to be under 3%

[E.Anderson]

well then, i guess my only option is new tires

[Brillo]

E.Anderson: Read post #29 in this thread. I directly answered your question and posted the formula for determining overall diameter. Allow me to quote myself - "an 8% difference in diameter will mess up your diffy for sure!". If you change the tire profile between the front and rear you must change the wheel diameter to compensate.
