TIRE SIZE - 315's or 285's on a 2-door bronco?

[lim218]

2-door big bed non sas.
added running boards, did a muffler delete, and im looking to upgrade my tires.

I am looking at between the falken wildpeak 315/70r17 or the 285/75r17.
I currently have no lift and will be adding a 2inch wheel spacer for both front and rear when I do the tires.

Anyone have any pictures of their 2-door bronco with either the 315's or 285's?

Are you talking about wheel spacers to push the wheel/tire out or a spacer lift to gain 2" of height? I don't think you don't want 2" wheel spacers to push the wheel/tire out that far. I'm not sure if the Big Bend wheels are wide enough for 315's, the stock Sas wheels are 8.5" wide and I think the Big Bend are 7.5" wide. The stock Big Bend wheels would probably rub with the 315's and need a spacer (.75-1.25") to push it out. You would need to remove the crash bars with the 315's regardless of the wheel. The easiest/cheapest route would be to look for some Sasquatch takeoff wheels/tires but the benefit of aftermarket wheels is the lighter weight and wide enough with a better offset.

So you are looking for a fair amount of poke?

.... and both of those widths are available on the Badlands model, look around any Ford dealer lot.

The height difference between the two tires will be about 3/4 inch, thus the lift effect will only be about 3/8" more for the 315's.
I really like the 285/75 , it's a great size, plenty of height, not too wide for my winter driving.

Width-wise, the extra width seems to make a pretty big visual impact, either tire looks much better than the factory 255's.

So pay attention to that while your at the dealer and see what it is you prefer.... in real life.

and here is something you didn't ask for, 35x11.5-17 on a base Base, no lift.

Non-SAS BD. Top left is stock 32s. Top right is with SAS takeoffs, no lift. Bottom is same SAS takeoffs with 2" spacer lift. Now running 2.5"lift with new coil-overs and 35x12.5x17 Mickey Thompsons and it is perfect!

Thanks a lot for your input and that was actually exactly what i was looking for! I also have a black 2-door that looks just like yours and I actually meant the 315/11.50r17 LT so you are RIGHT ON THE MONEY! same goes for the picture. Exactly what I wanted to see.
If i opt for the 285/75's - would a lift be required and would it fit on my stock wheels? (Specifically, the Falken wild Peake AT) I plan to black out the stock wheel fwiw and I am going for the poke so I plan on installing some wheel spacers.

I took this bronco over from my wife at 44k miles. I gifted my wife a brand new '26 tesla model Y so it was a fair trade lol

37's is as low as I'd go...

 

[buckybronc23]

Neither... Get 37s.

285's and the 35's are rated for the factory 7.5" wheel. No problem here.

The 315's are rated for an 8" wheel at a minimum, but should be just fine on a 7.5". Most tire shops will mount this, a couple may not.


285/75-17 = 34.1 x 11.6 (WildPeak AT4 specs)
35 x 11.5 -17 = 35 x 11.9 (WildPeak AT4 specs)
315/70-17 = 34.7 x 13.1 (WildPeak AT4 specs)

I BELIEVE ..... No lift required unless you plan to offroad it to the point you will be getting full stuff in the wheel well while at full turning lock. Street driving SHOULD not be an issue.
At full lock , on factory +55 wheels and 35x12.5" , most reports are to the effect of "just a light rub while turning at full lock".
The 2" spacers will make the tire swing in a different arc than mine does. Yours will stick out 1.25" more than mine. (twss)

The link I provided above "tiresize.com" has another cool tool that will let you visualize your poke/tire placement compared against a stock (or other) wheel IF you input all the correct info.
"Offset calculator"

Here's your stock vs 35x11.5 with 2" spacers.
