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

Kuro Intake Size - 17X7.0
I was thinking of buying these for my car would they sink in or be flush?



Sorry for the noobie question lol.

What is the offset? Wheel width means nothing without offset specs. You need less than a 32 to make it look good.

[MrAyasli]

+40 offset

so they will sink in?

Sorry for the noobie question lol.

I just had pretty much the same question. You have to find out what the offset of the wheel is. If you have the wheels in your possesion, the offset quote unquote by 6strngs: "should be stamped somewhere on the wheel on the back of the spoke or something. It'll say 17x7 JJ ET## or something similar. The ET # is the offset." After you find out what the offset is, There is a chart on page one of this post. if you still cant figure it out, ask someone on this post and somebody will help you. They did me. If you have not ordered the wheels yet, when you call on them to get a price or put the order through, ask them what the offsset is. Then refer to the chart or ask again for help.

Sorry he beat me to it. Yes they will sink in. That is the same offset as my wheels.

what about 16x6.5" and ET39, With a test fit I've concluded that a 10mm spacer will be enough to clear my gt4 calipers but if I'm getting spacers and longer studs anyways I may as well make it flush with the fender right?

look at the link in my sig to the flush wheel guide. It will answer both of your questions.

I did and I'm still having troubles understanding. According to the chart

FOR THE FRONT WHEELS ONLY **Your fronts should have been rolled from the factory. 9.0+ will probably need a bit of a roll to crush the plastic liner in a bit.
Width ---------- Offset (et)
6.0" ---------- et-5mm
6.5" ---------- et 0mm
7.0" ---------- et+10mm
7.5" ---------- et+15mm
8.0" ---------- et+22mm
8.5" ---------- et+27mm
9.0" ---------- et+33mm (you will be cutting it close with the strut. May need to start running negative camber at this point)
9.5" ---------- et+40mm (you will be cutting it close with the strut. Probably need to start running negative camber at this point)
10.0" ---------- et+45mm (At this point, you will need negative camber, a good fender pull and probably better off with a +35ish offset and going with wide fenders.)
10.5" ---------- et+50mm (At this point, you will need negative camber, a good fender pull and probably better off with a +35ish offset and going with wide fenders.)



FOR THE REAR WHEELS ONLY **You need to roll your fenders for all of these.
Width ---------- Offset (et)
6.0" ---------- et-20mm
6.5" ---------- et-15mm
7.0" ---------- et-8mm
7.5" ---------- et-2mm
8.0" ---------- et+5mm
8.5" ---------- et+10mm
9.0" ---------- et+18mm
9.5" ---------- et+23mm
10.0" ---------- et+30mm (Will start to cut it close with the strut. Negative camber may be needed. My best guess is you will be alright)
10.5" ---------- et+36mm (At this point, you will probably hit strut. Negative camber is needed. Probably would want to run a lower offset and just pull the crap out of your rear fender to make it tuck.)

If I am reading your chart correctly it states that if I have a 6.5" wheel with ET+39 I would need a 39mm spacer in the front to make it flush essentially right? and for the rear would be 54mm?

That seems like a rather large spacer.

My confusion comes from this


that is a 16x6.5" wheel ET+39 with a 12mm spacer on the front of my car...it appears to me that a 10mm spacer would be almost perfect....39 would be ridiculous.

subsequently here is the same wheel with 15mm on the back

seems to me like another <10mm would be a flush fit back there


Please tell me where I am misreading your chart or is my math just out to lunch?

Well, with the 6.5 you are running a standard fitting tire so the numbers will be different with you. If what you have works and you are keeping the wheel/tire combo then adjust it to what you think it needs. My numbers are coming from a stretched tire which gives you a narrower profile. You have tire bulge right now with the sidewalls making up some of the distance. I would venture that if you took off the tire and just put the wheel on the car it would need the extra mm to make it work.

Stick a ruler down there and see what your distance will be.

I have never tried to flush up 6.5J so my chart is just me doing number crunching and back tracking from what my current set up is.

[schmooot]

makes sense.....I'll do some measuring

[SoundSlut_dotcom]

OK, this si my final question... im Buying 19x 8.5 +45 ... WILL THE 8.5 FIT?! (esp in front? ) ????????????????????? HELP

[Harold_Fastwaker]

I don't think 45 offset will clear your strut housing. But I honestly do not know.

[jordisonjr]

I was looking at these set of Konig Lace rims, 18x8 with a 45 offset, the car is lowerd on tiens s techs. I read the the guide and I'm pretty sure these will fit, but does anyone know what size tire would work? I was thinking a 225/40/18 tire, can anyone give me some input on this?

[Promasta]

that is a good tire size, but a 45 offset is too high, it is meant for subarus. You are going to rub on the plastics in the front while turning. Someone claimed he had no rubbing with 225/40/18s on 18x8 +37s and lowered on tein springs. So you could get 10 or 15mm spacers and be good to go. Or go with a 215/40/18 tire and there would be less chance of rubbing.

[jordisonjr]

so you think 18x8 witha 45 offset would fit with a 10 or 15 mm spacer with 215 40 18 tire? Is it alrigth if it rubs on the plastic a bit? cause its really not gunna cause too much damage is it? as long as it isn't rubbing the fender? thanks

[SwissFerdi]

Yeah, rubbing the wheel well lining won't hurt much. I do so occasionally.

Is there any damage to your tires? or has the wheel well liner ripped out or worn down at all?

[SwissFerdi]

Honestly, I have not checked. It's very minor. I don't care about my tires at this moment since they're ripe for replacing, so I haven't taken a look at those either. I would imagine that the wheel liner takes more of a beating than the tires, but it shouldn't be much of a concern.

I rub the wheel liner as well as the control arm with my tires on my 4runner every time I turn sharp left. Over time it has rubbed a hole through the liner and polished a small spot on the arm but no real wear on the tires that I can notice (although they are quite knobby)

[MacgibaS2]

i've got a question.. +42 offset 225/40/18x7.5" TRD wheels with a 2 inch drop all around
what size spacers would i need to be perfectly flushed front and back?
-Mac

[Promasta]

marco's 18x8 +15s are perfect. so to look like his your 18x7.5's would need a 30mm spacer. but the largest i would go would be a 25mm H&R Trak+ spacer.

awesome.. 25mm spacers will be flush with the 2 inch drop? just want to confirm before purchase.
also, did Marco roll fenders?

[Promasta]

well everyone's definition of flush is different. but ya with 25mm spacers your wheels would be a bit more sucked in than marcos. I presume he rolled the fenders, otherwise he would hit the fender lip with the tire over every bump and even due to body roll.

[MacgibaS2]

who knows.. might just roll my fenders to install 25 or 30mm spacers and see how my car will looked slammed with 18 TRDs in black
