Wheel/tire size help.

I have a 2020 Tacoma TRD Off Road Double Cab Long Bed, and I am looking to add new wheels and tires to it. It is currently at stock height, and a lift will happen hopefully later down the road. I don’t know much about offset and backspacing, and whether it will effect the suspension/steering components or not.
From what I have found, I believe my stock set up is 16x7 with 25mm offset. I do not know what the backspacing is.
The wheels I am interested in are the Method 706. Also, I do not want to use wheel spacers.


The tire sizes I am interested in for the 17” wheel are:
255/80R17 (33.1” / 10”) “pizza cutters”
265/70R17 (31.6” / 10.4”)
From reading on the TacomaWorld forums, I believe these tire sizes will work without rubbing.



I am somewhat interested in an 18” wheel, as I have come to understand the new 22+ Tundra has the same lug/wheel pattern as the Tacoma now, and there’s a slight chance I might upgrade to a Tundra later on and want to bring the wheels over to the Tundra. If I plan on upgrading the brakes on the Tundra to a powerbrake system or something similar, from what I’ve heard 18” wheels are the minimum size that will work with the Tundra (please let me know if that is correct or not).


The tire sizes I am interested in for the 18” wheel are:
255/70R18 (32.1” / 10”)
265/65R18 (31.6” / 10.4”) This is the one I've seem listed as the largest on stock height.
265/70R18 (32.6” / 10.4”) Why would this not work? its stock width, but a taller tire.

If you could please answers for these questions for me:
1) I need to know if the wheels themselves will fit on the truck without interference of any of the suspension/steering components without the need for wheel spacers.

2) If the tire setup will be ok on the truck with the wheels selected.

Thank you for your time and your help.

 

Backspacing and offset are essentially the same thing but just expressed different ways. Some people like backspacing because it helps understand clearance on the inboard side. It's more commonly talked about in offroad situations like this and you'll find people use offset more in sports cars and other situations. Pick one, you probably don't need to worry about them both. Personally, I prefer offset.

You can use this website to compare wheel offsets, widths, tire sizes...

And remember that wheel width is important as well. Two wheels may have the same offset or same backspacing but if they have different widths then fitment will be totally different. You must factor in BOTH. That's why the above calculator is useful, it'll do that automatically.

Either of those 17" tire sizes you chose will work fine and that wheel size will fit without clearance issues for the wheel. Depending on the specific tires, tire size and alignment settings you may or may not have tire clearance issues. The pizza cutters will have more risk of rubbing due to their diameter but much better clearance than a 285 width 33".

Keeping the wheel tucked into the fender is the best way to prevent rubbing and the need to cut or modify for clearance. Going with highly negative offset wheels which pull the wheels out further is the easiest way to introduce clearance issues.

That 8.5" wheel is a little on the wide side for pizza cutters. Check the specs of the tire you're going to buy to see the recommended rim width for that tire and size. I'm running 255's on a 7.5" wheel and would prefer it were a 7" wheel. But plenty of others have run them on 8" and probably 8.5".

I can't speak much to the 18's, I always felt that's just too big for me.

 

Thank you for your reply. I will look around that link to see if it can help reassure me on fitment. I guess I’m hesitant on dropping the money for the wheels when I’m not 100% about the fit. I’ll have to look more at the 255 pizza cutter to make sure the 8.5 isn’t too wide for it. But I also think that the 17” wheel will have no problems on the stock setup.

I am trying to find out more about the 18” wheel, because if I do end up going with a tundra later on, it would be nice to not have to buy wheels again if I can possibly avoid it now.

 

On the 18” wheel the 5.68” Backspace may be too much. I know on the Tacoma 5.5 is about as much you can go before you run into clearance issue.

 

Thank you for letting me know that. Looks like the 18” is just out of the question for the Tacoma. 17” it is!

 

@Abominable Taco I would second your decision to go with the 17's. More availability and convenience. More common size in the 265/70R-17. Solid choice.

 

Those 17's with 0mm offset and a 265/70R17 will be very close and IMO will likely rub if the steering wheel us turned and the suspension is flexing. Mine had -10mm and they'd rub if I pulled into a parking lot or driveway too quickly. I also had to.renove my factory mud flaps. Just saying be prepared to lift it at least a little to avoid frequent rubbing.

 

Thank you for your input! I think I am going to go with the 17" In fact I'm on your site currently looking at the wheels and possible tire options. I'm thinking if I get a full-size truck later down the road, I'll just deal with new wheels at that point.

 

Thank you for letting me know. I do know a lift will be in the future. I'm currently contemplating the 255/80R17 size to try and mitigate some of the rubbing from turning, but I am looking at the size mentioned as well.
