Wheel Offset Guide, Unsure about proper offset? Look here first. Options

[WannabeGT4]

Ideal Offset in Relation to Wheel Width (standard ride height):
Width - Offset
7.0"-----30mm with 15mm spacer (effectively 15mm) *
7.5"-----31mm with 10mm spacer (effectively 21mm) *
8.0"-----33mm with 05mm spacer (effectively 28mm) *
8.5"-----35mm
9.0"-----42mm (probably too wide no matter what offset)

This will make the rim almost flush with the side of the body. These offsets and offset/spacer combos will prevent the "sucked in look" that the factory wheels have.

Ideal Offset in Relation to Wheel Width (lower ride height):
Width - Offset
7.0"-----36mm with 10mm spacer (effectively 26mm) *
7.5"-----33mm
8.0"-----40mm
8.5"-----46mm *
9.0"-----53mm (probably too wide no matter what offset)

The rim will sit just behind the fender. In order for the rims to tuck into the fender well on lowered cars the the rim must sit back into the wheel well by 11mm compared to the standard ride height offset recommendations.

* Clearance issues prevent the use of most rims with offsets lower than 30mm. The spacer will actually lower the offset and at the same time move the rim away from the offending components.
* 8.5" rims may or may not fit on lowered cars.

Offsets shown are positive.

Offset is measured from the wheels center line to the mounting surface.

so basically the smaller the offset the closer the outter tire wall is to the fenders?

Not exactly. Offset is relative to the wheel's width.
Larger offset means the mounting surface of the rim is further from the wheels center line. This will make the rim sit inside of the fender more, creating that "sucked in look."
Smaller offset means the mounting surface of the rim is closer to the wheels center line. This will make the rim sit closer to the fender but wheel width has to be taken into consideration.

This might be for a flush look and it will probably work for the fronts without a problem. I can tell you that if you have a lowered car and do that with the back, you will almost certainly need to roll your fenders. I have 48 offset wheels and 15mm spacers on 7.5" wide rims (effectively +33) and I just BARELY clear the inside of the fender without it rolled (by approximately 1 mm).

[WannabeGT4]

Thanks for the heads up jay. The math I used was based on Slowriders car with an 8.5" wheel with 35mm offset which should be equal to a 7.5" wheel with a 32mm offset and a 10mm spacer. I have no idea however wether or not his car is lowered... Maybe I'll do a revised list for lowered cars tomorrow. I'll use your measurements for a starting point. How far is your car lowered?

Approximately 1.75 inches. I could take a few pics if you want.

By the way, rolling the fenders is not necessarily a bad thing.

And, I think your measurements are probably pretty accurate for a "flush look". I just didn't want people to get the idea that they would be absolutely free from any clearance issues if they used your guide.

I will have to take one for you.

[WannabeGT4]

I added the offsets per wheel width for lowered cars. Would someone like to double check my math? I'm pretty sure it's right but a second opinion would be nice. And if anyone has 8.5" rims on a lowered car would you please chime in and let us know what offset you're running and if you have any clearance issues.

[JoKeRkId613]

This is good stuff. So from my understanding, adding the proper spacers can make your wheels sit flush with the body instead of looking sucked in. My rims are 18x7.5 and the company states they're 35 offset. My celi isn't lowered yet. but on the chart, it says that 7.5" wide rims are 31 offset... so you would need a 10mm spacer to make it look flush. how wide would my spacer need to be if i have 35 offset right now? i plan on dropping it 1.5"all around. i would need 4 spacers, correct? im just making sure this is for both the front and rear. thanks.

[WannabeGT4]

If you plan on lowering it you don't need to do anything. 2mm spacers would be the only thing that would fit and it wouldn't be worth it in my opinion. Honestly, I've never seen wheel spacers smaller than 3mm anyway.

If you're not lowering it you'd need one 14mm spacer for each wheel to get the rim flush with the fender.

Justin are you sure that a 40 offset on a 8" rim will clear the strut tower?

[WannabeGT4]

Justin are you sure that a 40 offset on a 8" rim will clear the strut tower?

If not, then 8" rims won't fit at all on a lowered car. +40mm offset on an 8" rim should be as close to the fender as your 7.5" rims with +33 offset which means there is no more room to subtract offset to clear the strut tower.

EDIT: I just checked tirerack and they sell Gram Lights 57pros that are 18x8 +48mm offset for our cars so 8" +40mm offset should fit fine.

ok cool. is this the case with any type of lowering? if i lower it 2", would the same still apply as far as needing a 2mm spacer to be completely flush(i checked and they exist)?

[WannabeGT4]

You won't be able to tell a difference with or without the 2mm spacer.

[CelicaZR]

Sorry to bring up an old thread.
I'm currently looking at these wheels
I like. They are 18 x 7.5 with an offset of +43.
Would this work on my car?

This post has been edited by CelicaZR: Mar 29, 2006 - 5:42 AM

[WannabeGT4]

It'll fit but it will look just as sucked in as the stock wheels. You could run 10-20mm spacers to make it look more flush with the body.

[CelicaZR]

Cool
Thanks Wannabe.
I guess I'll look for another set.

My g/f is about to be putting some 17x8's +35 with a 1.5in drop all the way around. I'll have some pics and info by the end of this week. Hopefully it all clears If not we may have the roll the rear fenders alittle. Should be a pretty sweet setup though!

You could actually use 15mm spacers on GTS rims to get them flush as possible.

[bufferdan]

17x8 +35 Offset with 215/45/17 ...Fronts are pretty flush...i think the rear still could use a 10mm spacer bringing it to +25 to be close flush.

But how low are you? 32mm would probably be just fine on a car if it's not too low and not running too wide of a tire, but if you are really low and want to ride on comfortable tires my bet is on the 40mm offset.

Those will fit a 7.5" rim fine. If you are going to go for an 8" rim, I would look for a slightly larger tire if traction is an issue.

[jdg371]

So 8in is too wide for 225/50s? what size tires would be good for 16x8 245/40?

[malpaso]

So 8in is too wide for 225/50s? what size tires would be good for 16x8 245/40?

No it's not. For 225/50s you can use 6.0 - 8.0 rims

see topic here ("recommended combinations rim and tire widths" table) for more info

40mm. No spacer.

ok, i figured i should have never bought the spacers. i can only seem to find 17x8 w/ a 35mm offset, i dont think it should be a problem though because my car is lowered on H&R springs that drop it about 1-1.2" I am also going for the same overall diameter.

some guy is selling his 7.5", + 45mm, 225/45/17 which I'm guessing won't be too well for a stock suspension celica since the off set is too high. Am I right?

That'd be about half an inch further sucked in that stock rims. I'd pass on those unless you're getting a killer deal and don't mind running spacers.

You can buy those and get some spacers to bring it out a bit more. A 5mm spacer won't hurn anything. I have +42 wheels and they fit fine, but I am looking into 5mm spacers to bring it out.

EDIT: the wheels you are looking at have the wrong bolt pattern. Those are 5X114. You need 5X100.

The Enkei's would fit provided they are the right offset.

17x8 +35 is a good setup for the 6gc. Tire size is up to you though. You can stretch a 215/45/17 or go with a 235/40/17. You "may" get slight rubbing in the rear depending on how low you are with a 235/40...not that big of deal just roll the rear fender lip in alittle. There has been pictures posted in this thread with this setup.

a 15mm spacer would get it flush. otherwise it'll be sucked in. I dunno about the clearance issue though, but it also depends on your tire size.

If you put an offset, arn't you taking the risk of loosing control over the car since your putting something over original?

It will look pretty good (depending on if the rims look good). 17x8 is a good size rim and with 42 offset you're looking at a fairly close to flush look, which is always good. If you lower it it will look better and clearance may be an issue on full steer but there are ways around that. Only way to know is to drop it.

anyway, acording to this guide, for a 17x8 the ideal offset would be 40mm. if you've got 42, that's only 2mm off, you wouldn't even be able to tell the difference. though I've been told 17x8 with a 35mm offset is really flush too. in any case, I think we need to run staggered wheels in order to have anything perfectly fluch anyway.

that's a lot of space though... you'd probably need longer studs in order to fit a 25 mm spacer.

I said 15mm because you're lowered. If you weren't, 25mm would work without question.

Well if I went to 25mm I would get new bolts ...same if i went to 15mm ...just not sure with what I can get away with

[6strngs]

25mm is almost one full inch, if when you put your wheels on now, if you think you have one inch of stud sticking out plus enough to thread on 6-7 full turns of a lug nut, then you're ok. lol.

Why do you guys buy so narrow rims? Wider rims and tires always look better and makes the car better to handle.

more expensive, and also weighs a bit more so it'll negatively affect accelleration. there's also a much wider selection of 17x7 then there is 17x8.

[Daftboy]

As he said.....plus the only way too get 8JJ for my rim was to go up to a 18" which kills acceleration and handling.
