you would need 4 of those spacers one for each wheel. You would not need longer wheel studs ,since the spacer has its own lugs on it.

and yes that 20x8.5 with a 10mm, 14mm or a 15mm offset would work. But a 15mm is the largest offset you'd want to run.

hey dave, seen as tho you basically got this backspacing stuff on lock, im just TRIPLE checking my numbers/figuring on this.

20x9 up front with a 5.125" backspace and a +10 offset work on a BD'd 2nd gen? also, what tire would you suggest, 255/35 sound good?

and for the rear, 22x9.5 with a 6" backspace and a +20 offset. Incase you are wondering, yes, they will be custom narrowed frame rails....however its going to be on a blazer disc brake rearend....any problems or spacers i need to know about? ...and i was thinkin a 295/30 for them....sound about right?

yeah man, sounds pretty good. the front will work just fine, that extra little bit of backspacing over the norm will help out so when the truck is laid out flat it will clear the fender lip and so still be able to turn a little... assuming the wheel tubs are large enough that is. As for tire size, yes a 255 35 will work just fine. Now im sure you realize that with a 9" wide rim theres no way around the rubbing on the frame issue when your turning.. unless ya turn like a mac truck that is

for the rear ya had me worried there until you said the rails where gona be narrowed some. Id bring them in 3" on each side, that will give you plenty of room to clear those rims. I wouldnt see any problems with the blazer disk rearend i wouldnt think. Just remember those 295 30 22's are gona be about 29"" tall, so make sure everything is gona clear notch and frame wise.

so 5x120.65 is the same as 5x4.75 correct?

and a 20x8.5 with a 12mm offset will work good?

Yesterday I try to order some 20x8.50, RWD mm, 5x4.75 Inch, rims and I told the guy that I have a 1985 s15 2 wheel drive with a 5/5 drop and would like 15 mm offset . The guy at the shop told me I needed a 20 mm offset for 5/5 drop and he suggest 235/55r20 tire is this correct. Need to know befrore I order.

[idragbodys10]

what the backspacing and offset for a 22x8.5 wheel??

[wirrrey21]

if i have a bagged and bd'd 1st gen, and i want to stuff a 20x8" rim in the front, what backspacing and offset should i get? i was thinking either 5.0" or 5.5" backspacing but not sure which one. and i'm not too sure on what offset either.

Ok i guess ill take a jab at this one now. I'm ready to order some Boyd Magnetos or Smoothie II with the mesurements of "20x8.5 5-120.65 --- Fits Small GM 5 on 4 3/4 Lug Pattern, 5 inches of backspacing". My Driver is a 98 ex cab with a 2 - 3 drop, 2" spindles in the front and 3" blocks in the back. My question is should i go with the 5" bs or the 5.25"bs and will these rims tuck under the fender when i bag the truck, whats the word 98layinframe.

hes full of it. If anything 15m is the max you'd want to run, a 5mm or 10mm offset would be even better to run. Ya have to remember the larger the offset the more the rim is going to stick back into the wheel well.... causing more rubbing on the frame and control arms when turning.

5" or maybe up to 5 1/4" if they label it in backspacing, and if its labeled in offset then right around a 15mm.

allready answered your question. Congrats on the nice wheel purchase Cant wait to see your truck whens its done mike.

5.5" backspacing. thats gona be a big wheel tire combo to tuck back there. Maybe a tire size of 295 30 22 might fit nice.

youd need the same as posted above... for a 8.5" wide rim your gona need a 4.75" backspacing. Or if the wheels are listed with offset, then a 0mm thru a 10mm would work best for ya.

As for prices and styles.... i have no idea man. It all depends on what you like. Ya can allways check out ebay for some cheap wheels. Expect to spend around 900+ for the rims and anouther 400+ for the tires.... just as a minumin price range.

98layinframe,
I'm interested in the 20" Neeper N5's and they come in our bolt pattern, but they have a hub bore of 72.56mm. Is that gonna be a problem for the hub? Also, are the dust caps gonna fit inside the small caps on the rims? Here is a link for ya.
http://www.dubspin.com/wheel.cfm?brand=2&cat=96
My wheel guys said that they come in 8.5 inches wide, 15 offset, 5.3 backspacing. Will those fit good for a bodydropped 2nd gen s-10? I think that I want a 245/35/20 tire on them.
Thanks in advance,

Would a 15mm offset with a 4.75 and they are 20s. Would that be a good offset. And the tires are going to be 255/35/20. I am going to drop my zq8 2 front and 3 in the back.

Sorry but im not all that sure about the hubs there. In those pics the wheel sure doesnt look like our trucks big o'll hubs would fit in there all to well. As for the info your wheel guy told ya, yes hes correct that 5.3" backspacing will work just fine, just as long as you realize your gona experice some rubbing up front when turning on that wide of a rim. For the tires, yes you can either run those 245 35 20's, or also a 255 35 20 will work just fine.

yes as long as the backspacing is under 5" up front the wheels shouldnt give ya much of a problem at all. Just remember man, a ZQ8 + a 2/3 drop is really basicly a 4/5 drop so your gona be really close up front and the tires are gone rub when turning or possibley bumps.

[crusheroz]

ok people, I guess I'm gonna be the first to ask this about a 4X4, I have stock rims, I want at least a 15x8 in rim, I understand that my backspacing and offset is rediculous, no tire/rim places around tacoma that I have found want to mess with me on finding me a rim that will fit. I guess they havent experimented with this. I just need to know what my offset or backspacing needs to be for me to have a nice size tire, preferably a 255/65/R15. Also, will I need to clear any fender and or wheel well trim away from the tire. I have a 94 4dr blazer, the first gen. Be easy on me, I'm new, I have owned a 1991 lowered extended cab, I'll see if I can post it later but I'm transformed to a 4x4 cuz its an LT,, loaded,, very nice. Thanks guys/gals.

[98layinframe]

4x4's use the same offset and backspacing as the 93+ camaros do. If you would be willing to up the wheel size to a 16" you could simply pick a set of stock wheels off the camaro. If your stuck on a 15" rim, then when you go to the shop, just tell them its for a camaro and not your truck.

[crusheroz]

Ok so, say I go with this offset for 93+ cameros, what kinda tire size am I looking at for the max? Again, I know this is a bunch of two wheelers but hoping to look for someone who has dealt with this stuff already. 4x4's have a front end that sticks out further then the rearend and I'm even thinking of changing the offset for just the two rear wheels to match the front. Of course I will probably have to get aftermarket fender flares to cover the tread. Washitonian cops dont like tread showing but I'm not too much worried about it.

[B01s10]

I am gonna say i fall into the catagory of not understanding... this is what i have figured...I am goin to buy 17x9.5. i have figured a 5.25 backspacing being correct. That should keep it evenly wider from the stock rim once mounted. Correct?

Crusheroz

the camaro rims will fit the exact same as your stock 4x4 rims due so there not going to stick out any farther at all. If you want the rear to match the front you could pick up a set of 1" thick spacers for the rear wheels to match them out with the front better.

As for tire size... is the truck lowered, lifted or stock height? Are you looking for a tall tire, or just something that is stock height yet much wider?

well first off thats an extremely wide rim to mount up front on an s10 so plan on having rubbing on the frame and possibley control arm when turning. That size and backspacing will work, but a 100X better option if at all possible would be a 17 x 8.5" width a 4.75" backspacing up front and a 17 x 9.5" width a 5.5" backspacing out back. For tires a nice size would be a 225 40 17 up front and a 295 35 17 out back.

[B01s10]

I have decided to go with 245 45 17 all around. on a 17x8 with a 4 in BS. i want to widen the truck as much as possible without diggin into the fender edge when hard cornering. will 4 work or could i even do a 3.75 maybe. i have a 3/3 drop. THANKS!

[98layinframe]

yeah 4 will work, but dont go any smaller at all.

[SimplyUnique]

to much math today ....... 22 x 9.5 ... what backspace do I need to tuck in the front ... 5"?
