Backspacing help........

About to pull the trigger on some Fuels. Looking at a 17x9 but am seeing different offset numbers when searching for my 2015 DCLB Sport.

I think what I want is 4.5" BS with -12 offset. Also available is -1 OS (I don't think I want this).

So my question: I plan on running a 265/75 or 275 and may switch up to 285's later. Will the -12 offset stick out too far? I would think the -1 would not allow me to run 285's later.

From what I've read using the friendly search button 4.5" BS/-12 offset is the way to go. It will give me a wider stance with the 265/275 (which I like) and allow me to run 285's later....

.... did I just answer my own question?

I also see a -20 offset.... why would someone do this? Seems to me it would stick out waaaay too far......... Maybe if I was trying to run a 35" inch tire?

Oh - and will a 265/70 fit on a 9" rim?

 

Why are you looking at a 9" wide wheel? The max that I would recommended is 8" wide. Many 265s will not mount on a 9" wide wheel within the factory tire spec. Go to tirerack.com, look up your tires you are interested in and check the specs. 7.5-8" wide is ideal. Especially if you plan on going off road where you may air down, the narrower wheel will hold the bead significantly better.

9" wide with -12 offset is going to put the wheel about 1.25"-1.5"+ past the edge of the flare. Meaning the side of your truck is going to be peppered with gravel or whatever else your tires can throw at it. Not great on the paint. I personally prefer my tires to be right at the edge of the flare.

I have 17" x 7.5" x 6mm offset, which puts my tires right at the edge:

I'd expect the -1 offset to work for the 275s, as they are 5mm wider off center than the 265s, and have 7mm more room than my +6 offset. Not sure about the 285s. Something else to keep in mind, if you get your 265s in C-load, they are going to be drastically lighter than 275s or 285s which almost always are E-load. The significant weight difference will affect acceleration/power/mpgs/braking and handling. Not worth it IMO for a daily driver to gain the .25" (275) -.5" (285) more ground clearance from the larger and heavier tire.

 

After reading through 30+ pages of offset threads I pretty much came to the same conclusion. Have started my search for a more narrow wheel in the 8" range. There are some 265 that will fit a 9" rim but that limits my choices.

This exactly.......! My OCD would kick in and sandblasting the sides of my truck simply driving around would probably make me crazy!

Nice truck! I like the stance and height. After reading the "war and peace" version of tires and rims here I'm looking at a 265/70-75. I don't want to deal with any trimming (potentially) so 285's are out and most importantly don't want to kill my mileage for the sake of a tiny bit more clearance. 275's weight more (and cost more, usually) so I'm other than looks I'm not really seeing the benefit. I'm averaging 18.6 mpg since March 2015 and that's disappointing since I was coming out of a compact that was getting better than 24 - but it's a truck - I knew what I was getting into!

Thanks for the feedback - definitely helps my thought process.

 

Options I would recommend for a stance similar to mine are the 17"x7" TRD Pro SEMA wheels and run 265/70R17s (available in gunmetal grey and black), here is an example:

Link to the SEMA wheels thread with places to buy starting at about $161/wheel.

Or the TRD Baja/Pro beadlock style 16"x7.5" wheels and run 265/75R16s (available in 3 colors, grey, black, bronze).
https://www.tacomaworld.com/threads/trd-pro-tx-baja-official-thread.360056/#post-9752674
About $70-80 more than the SEMAs, black and bronze are cheaper:

The OEM wheels are high quality and light weight, the SEMAs are 25lbs and the Baja/Pro beadlock style is 23.5lbs. The offset will be a little less on the SEMAs since the wheel is a little narrower to push the wheels out so both are about equal to the edge of the flare. You really cannot beat the OEM wheels IMO.

I'd look at what tires you want to run to determine the wheels. For example the KO2s only come in the lighter C-load in the 17" tire size, 265/70R17. So if you want the KO2s I'd go with the SEMA wheels. Otherwise you will have the heavy E-load version in the 265/75R16s which will affect acceleration/ride/mpgs ect. On the other hand the Duratracs come in 265/75R16 in C-load. So be sure to pair the wheel tire combo together to get the optimum of what you are looking for. I went to 17s specifically so I could run the KO2s in lighter weight C-load and like them much better than Duratracs.

Lots to consider.

 

For additional reference I'm running the SCS stealth 6 https://www.tacomaworld.com/threads/scs-wheel-lineup.419636/#post-12000537 on a 265/70/17 tire. Mine do stick out a little bit but its not to bad. Plenty of pics around of those mounted on same tire.

 

Thinking Method Standards - 17" x 8.5" width 0 offset. 32 lbs. Cooper Discovery AT3 265/70/17 - C rated tire.

My "wheel math" says they'll stick out about 1.75 inches further than stock. 1 inch wider rim and .75 less backspace - Hope that's right........

** edited - fat fingered the tire size. Corrected to 265

 

They will stick out 3/4" further than mine. My wheels 7.5" wide with +6 offset.

32lbs is a heavy wheel. Stock OR wheels are 23lbs. Rotating weight is said to be the equivalent of 4x static weight, meaning 9lbs x4 wheels x4 = 144lbs. Plus the tire weight increase x4 tires, x4. Stock OR tires are 38lbs. I realize you don't have an Off Road, but using as a point of comparison.

 

Yeah... pleasantly plump - I'm helping the wheel weight with the 265 as opposed to a 275. My Sport stockers are heavier than your OR's (25.5 or so I've read here) so that also helps........ so 104lbs. Balancing the look stance and performance is tricky...........

 

Yes it is. Here was my thought logic on wheel tire combo when I did mine trying to balance it:
