Installed 33 inch tires on stock Base rims - no mods required

That… is a fine-looking bronco. Nothing like what I ordered, but damn… looks great.

Winning!

I still don’t understand offsets. How would these tires look on a wheel with a +35 offset?

You will stick out just shy of 1" more and have just shy of 1" more interior clearance.
I should clarify. The center of your tire/rim will move farther away from the hub by the offset difference.
Use the link below, it’s a great tool.

I was looking at doing that to mine but according to Tirerack that tire requires a 7.5-9” rim width. The base 16” rim is 7’s wide. Probably the reason for a bulge in the middle. Compensating for that issue with lower tire pressure to me would only lead to further problems. I’m sticking with 265/75/16 Goodrich T/A’s. A 32” tire which is what is stock on a BB & OB.

Thanks for taking the time to do this and show us exactly what I needed to know.
I have a Base 2-Door on order since March, have already ordered my Ultra 17x9 +25 rims and hub adapters. I was waiting for confirmation before getting my tires, either the 275/70R17 or 285/70R17. I know I can go with the 285's. Almost identical height to you 16's shown.
The 285/70R17's on a 9" rim with a 25mm offset looks like they will work great.
I'm looking at either the Goodrich T/A's or the Cooper AT3 XLT's.

Thanks again for taking the time do do this.

Whoa, really? What is the offset of the stock wheels?

Thanks for the R&D. Super jealous you got you Bronco past QC! I’m having a hard time deciding between this and the 265/75/16s. Need more pics! Thanks!

These are 285-75-16 tires (technically a diameter of 32.8 inches) , mounted to stock Base Bronco rims. No lift or spacers, and no rubbing in my testing. That increases the stock 10 inch tire width to a much beefier 11.2 inches.

See video linked here for full testing with shocks/springs compressed and extended:


I think 33 inch looks great on the 2 door, and for my light off-roading needs is a good option for getting a extra inch+ of ground clearance while saving $4000+ as compared to the Sasquatch option.

Let me know if any questions and I will do my best to answer them!

Great video
Well done
Nice look, much better than stock
Paint rims and top next?

0 I believe.

I was told it’s a weird wheel, because it has a trucky lug pattern of 6 x 5.5 but with a car like offset of zero, leaving few wheel options.

Cars typically have a high-positive offset, not near-zero.

I looked it up here: https://www.bronco6g.com/forum/threads/-2021-bronco-oem-factory-rims-wheels-specs-sizes-offsets-.11893/

...and it looks like stock is +55 which is indeed different than what I would have expected. Thus,
Jsullivan's answer would be correct.

Nice! you did what most people were thinking about that base... can't wait to see what you have planned next in the paint shop

Other than the look of The Pizza Cutters, any concerns with the 255/85/16’s
Wouldn’t need to worry about the bulge and rim width, right?

 

[Jsullivan]

Whoa, really? What is the offset of the stock wheels?

55mm on all but Sas which is 30mm.

Love the look of your Bronco, reminds me so much of the original. Color goes great with the grey top too.

I plan on also adding tires, but thought about switching to 17 inch rims. But following your example I think I will keep the same rims and upgrade to bigger tires. I don't know if I will go to 33's though. Please post any issues you encounter. Also thanks so much for being the guinea pig on this.

Looks great!!! Personally I would loose the flares. Just my opinion not a fan of fender flares. First time I really like the steel on the bronco. Good job!

Stupid follow up question: Could the dealership recalibrate the speedometer to correct for the 33's ?
