Wheel Offset/backspacing question. yes i searched, need help

So i currently have stock 16" wheels on my 2007 Tacoma Double cab offroad. so they are 16x7 wheels correct? tires i have on these wheels are 285/75/16 km2's. i have spidertrax 1.25" spacers installed front and back. i love the look of the wheels how they sit and such on the truck. i am looking to buy new wheels same diameter and width as my stock wheels but want to change the backspacing/offset so i do not have to run spacers and at the same time keeping the same look. so what backspacing/offset wheel do i need to keep my same look but ditch the 1.25" spacers?? any help would be awesome. thanks in advance

 

4.5" Back Spacing

 

I would run an 8" wide wheel with 0 offset, 4.5" backspace. That will give you the look you want. Plus it will help those 285's spread a little bit for more footprint.

 

thanks for the help guys!

 

That's 3/4" change from stock.
That's what 1st Gen TRDs are like I'm running.

On an 8" wheel 0 offset would be 4"

 

Yep my bad. I looked at a chart one column off.

 

4.5"BS/-12mm offset, is ideal for second gens with 285's.

 

False. 8" wide wheel with 0 offset is 4.5" bs. 8.5" with -6 off is 4.5"bs, and 9" -12 is 4.5

 

So maybe I can read a chart. I wasn't looking at it again to double check. Sarcasm. People are always tough on the internet.

 

Look at the picture.

 

I have the same setup as the OP. I want to replace the stock rims with 16X8 or 16X9. To compensate for the 1.25 spacers I have as well as have the tires stick out about 1 " more, what offset or Backspacing would I go with in both 16X8 and 16X9?

Thanks

 

to match 1st gens, stock 4.5 BS with 1.25" spidertrax, you would get a wheel with 3.25" BS with out the Spiders....

to match 2nd gens, stock BS 5" with 1.25 spiders, get a wheel with 3.75" BS without...

the offset will vary depending on the width of rim using the above.....assuming 9" rim...

you could add another .5" BS to either...or not...

the further out you go, the more problems with other stuffs...main thing is keeping everything hubcentric, no matter what one does....

Peace...

 

ok so im going to go for the 16x8 wheel with 4.5" backspacing/0 offset. bolt pattern i need is 6x5.5 just not sure what center bore i need for the wheel. its a 2007 tacoma offroad 4x4. anyone know what wheel center bore i need to fit hubsentric on my hub?

 

i found a set of wheels i really like, measurements are

16x8 wheel
6x139.7 bolt pattern ( same as 6x5.5 correct?)
106.10 center bore of wheel
offset +1.

is that the correct size bore and what backspacing is +1 offset?

any help would be awesome. thank you.

again i will be putting my 285/7/16 tires on the wheels and will be going on my 2007 tacoma offroad 4x4 with a 3" ome lift with dakars.

 

6x139.7 bolt pattern ( same as 6x5.5 correct?) YES

106.10 center bore of wheel

I have no idea +1, it could mean 3" or 5" BS, 5 is same as 2nd gen alloy stock, maybe a quick email or toll free call?


Good Luck

 

From another thread

 

106.1mm will be hubcentric for your Tacoma, so yes, they'll work.

+1mm offset on an 8" wide wheel = 4.54" back spacing.

Backspacing formula (if you know the offset)

1) Convert offset from millimeters to inches by multiplying by 25.4 (there are 25.4 mm in an inch). Write this number down.

2) Apply this formula: (Wheel width + 1") ÷ 2
Wheel width is measured from inside the two outer flanges. You are adding the 1" to account for the thickness of the flanges of the wheel, which is .5" per flange, and there is a flange on the outside and the inside, thus 1" of total flange. Dividing by 2 will give you the dead center of the wheel as measured from the extreme outer edge of flange to flange.

3) Add the offset to the number you got from step 2 (if the offset is positive) or subtract the offset if it is negative.

 

One more thing -

The 16x8" +1mm offset wheels will sit outward approximately 1.75" than your current 16x7" stock TRD Offroad wheels.

 

awesome thank you for the good info guys!
