Wheel offset?!?!

Hey new to the forums. Just bought my first Tacoma. 2021 TRD off road. I currently have the stock wheels with Falken wildpeak tires (265/70 r16). I’m looking to upgrade to 17” wheels with 265/70 r17 tires. I’m hoping to have the tires poke out enough to be flush with the fender or maybe a tiny bit more. This whole offset thing has me confused. How much of an offset would I need to achieve this? Any help would be greatly appreciated.

 

-25

 

Depends on your rim width mainly.

Understanding what offset and even backspacing is will really only give you good results. Asking for opinions is like @$$holes... everyone has one.

Offset is when you take how far your actual rim centerline is in relationship to a perfectly centered rim. Most fwd's have neg offset and rwd's generally more positive. More positive more poke

. For example a 10 inch wide rim with 0 offdet would be centered. The same rim with -25mm (1 inch) would bave the center line offcenter (moved over) 25mm (1 inch). Or when measured would be 100mm (4 inches) inner rim lip to center line and 150mm (6 inches) outer rim lip to center line..

To confuse things that is also 4" backspacing

 

Offroad stock wheels are 7" wide x 16" diameter, +25mm offset.
A 1" wheel spacer (-25mm) will take the stock wheel to a zero offset position, which will be close to flush on those 265 width tires.
I had the same situation with my 2016 OR but I ran 1.5" spacer for a couple months before buying new wheels at slight negative offset.

 

As everyone already said. The more negative of an offset you go the further out the tire will be. Take a measurement for where you want your tire to sit and go from there. For example if your current wheel is a +25 offset and you measure and need the wheel to be 2" further out, convert that 2" to mm and subtract from current wheel offset. So +25mm minus 2" (roughly 50mm) = -25mm offset wheel to sit where you measured to

 

My stock wheels were a +30 with 245s. I upgraded to a 0 offset with 265s. Here's the result.

 

Backwards. Its ez to do

The more negative -, the more INset the wheel
The more positive +, the more "poke"

 

Negative ghost rider

 

Negative on the negative.
0 offset = centered
Negative - offset (most fwd rims for example) sit with centerline inset or negative "poke",
Say -25mm is normal offset
-45mm would be way inboard
Thats why fatter than o.e. rims generally have more negative - offset to spread the additional width

 

Are you saying a 17x9 wheel with +25mm offset will sit further out than the same wheel with a -38mm offset? Riddle me that

 

My apologies. I have been thinking backwards for years. Wow my bad

This helped me ...

Im so old school i guess, I've always used backspacing as my measuremen

 

You might want to double-check that. You're visa-versa on negative vs positive. Stock OR 16" wheels are +25mm, stock 17 and 18" wheels (non-pro trims) are +30mm. Most Pro wheels are +4mm

Most TW members prefer either +4, 0, or -10 offset. Going too negative with a wide tire will kick gravel into your own paint.

Here's a fun comparison. These are the same exact tires, same exact suspension. 265-70/17.

Stock wheels are +30, the 4Runner wheels are +4mm. Notice that it pokes more with a delta negative 25.

 

Super easy. 17x8 0 offset and call it good.

 

Here is an additional LINK that might help clarify how offset works.

 

Agreed. I always recommend 16x8" +0mm or 17x8" +0mm to achieve the look and fit that @LVtaco76 described. This is about as optimal as it gets for the 2005-2023 Tacoma.

8" rim width with +0mm offset maintains the ride quality and drivability. There is minimal (if any) rubbing with 265/75R16 or 265/70R17 tires, and the rubbing is easy to remedy should you have any.

 

Would there be an issue (alignment, tire rod wear ect) with putting 18x9 wheels with 265/60/18 tires on a 2023 toyota tacoma 4 door 4x4? What, if any, wheel offset would I need? Thanks in advance. Right now the 245/75/16s have so much tire flex I think I am in a 1977 cadillac.

 

I’m running -10 off set and it has alittle poke and I’m still able to tuck my tires without ripping my fender flares off.

 

LOL! I think you have a little more lift than I do. The firestone destiny tires just have so much tire flex. All online sites show that very small difference between the ride height of 245/75/16's and 265/60/18s. Its the rubbing Im concerned about. What if any offset on 18x9 wheels should I get?

 

For your 2021 Tacoma :

18x9" +0mm offset fits perfectly with 265/60R18 tires.

An offset that is higher than +0mm on a 9" rim width (i.e. excessive positive offset) will put the wheel/tire too close to the upper control arm, particularly if you install wider tires in the future. Technically you could get away with something between +0mm and +6mm (maybe even a few millimeters higher than +6mm on the offset) with tires that are only 265mm wide, but if you ever want to go up to 285's in the future you'll want +0mm offset otherwise you run the risk of the tire rubbing on the inside.

On the other hand, too much lower of an offset (i.e. negative offset with 9" rim width) will cause your tires to rub on the front bumper and/or backside of the wheel well, which in turn will require trimming and possibly other modifications.

18x9" +0 with 265/60R18 won't cause any issues.

I'll try to come up with a picture of that exact set up for you (18x9" +0 with 265/60R18 on a 3rd Gen Tacoma), but in the meantime here's a good picture sent to us by one of our customers who has a mild lift and 275/65R18 tires with our 18x9" +0mm BFD flow formed wheels (thank you to the customer for the picture!):
