Since that stick was created, its been discivered that our cars have quite a bit more tolerance for backspacing and offset. The 20x10 Eagle 225's used by several members with lowered cars, have an offset of +2. Which is about 5.57 inches of backspacing. So there is some room for error in the recommended specs at the top of the page.

If your wheel has 6.8 inche BS, and the recommended is 6.5 inches (see chart at top of section) You may not need a spacer at all. a 1/4 inch spacer should give you a good fit, if you need it at all. Have the wheels redrilled and have the center bore opened to 78.1 and you should rock.
That's the great thing about BMW wheels, they usually dont need adapters.

Yeah that is a good call Wood, I did notice that there was some wiggle room with the backspacing.

1 1/4 adapters

Stock look on a Caprice with no adapter,yes my frame is still shifted but I'll fix that later

Driver Side


1 1/4 placed ''1.25'' nice and flat and safe! never had problems going a 100mph with em on. Yes I used 3 bolts only bc I'm showing you guys pics lol I didn't go anywhere.

Pics with the stock SS wheels and tires on with the 1.25 adapters








Its way better looking with the 1 1/4 adapters!! looks way more Beef'd!!

Passenger side is a lil problem tho,if your frame is shifted it will rub with 3 ppl in your ride

To fix that you either get your frame shifted straight bc their still room to spare on the driver side,Or you can hit the moulding with a sledge hammer in the inside until it lays flat.

If your mouldings are shaved your good to go and don't have to do the other 2 things I just listed. I did option 2 sledge hammer

pics, No adapter on



with a adapter on,this is the side that pokes out more,sorry i didnt put the car down bc the whole rear was lifted with no other tire on the left side anyways pics

Adapter help

I wanted to inquire with you guys before I go ahead and get a wheel alignment with my new setup

I'm running 2" adapters 5x5 to 4.75 for a pair of ROH rims on 275-40-17 tires.

I'm currently rubbing on both sides in the rear but more on the right..

I recently purchased 1" adapters that are on route and wanted to know if having having the rears reduced this 1" will effect the wheel alignment or have any other issues that are involved?

Does running two different sized adapters on the front/back wear a certain side faster?

bump.

Sometimes I have to use that stickies, too!

I have a set of 18x8.5 wheels with a +13 offset sitting in my basement from another project. They're 5x120, so I'll have to use adapters or redrill.

Using the above calculations +13 converts to about 5.25 backspacing...And a 1 inch thick adapter makes it 4.25...And that's not likely to work at all.

But just to be sure I'm gonna take one to work and slide it under the car and measure the space btween the mounting pad and the drum. I might get lucky... but the math says no.

We shall see.

18X9.5" Vette wagon wheels on RMW

Hey i've been away for awhile, now i'm back trying to help my brother with his 1994 Roadmaster Wagon. He wants to put a set of 4 18X9.5" Corvette wagon wheels on his wagon and we can't seem to find the right spacer and tire. it's a daily driver, so all four tires should be the same size. we were thinking about the 245-55-18 tire that you specified, but didn't know if it would fit the 9.5" wheel ok. also we know the spacer has to be a hubcentric spacer, but we don't know the size or the best source.

thanks in advance for your help!

There are several variations, but a picture would help to ID the specific wheel, and if they're OE wheels, the back data is also going to help.

Offset is the important key piece of information needed. If the wheels you're talking about are Z06 fronts, they're +40mm, but everything else in that size was more like +56/57mm, I recall.

The spacer/adapter for a +40mm wheel at 9.5" will be in the 30-40mm range, and if it's +56mm, the thickness will need to be in the 50mm range, depending on where you want to place the wheel laterally--with a wagon, there may be a more restrictive spacer range for the rear, depending on tire size.

As for tire size, the 9.5" bead width calls for a 265 or greater tire section width. Trying to stretch the 245 tire on the 9.5" wheel is not a good plan--for the tire or the wheel. Not sure about load rating, but pulling the sidewalls in is also going to leave the wheel very vulnerable to curb damage.

I've got some 275/45-18 Continental tires that are old but "new" (never have been on the road)--I'd like to make them yours, if you may be interested.
