37s on a 2.3L?

[JerryG]

I am running true 38" tires with a 5.38 gear ratio on 2.3 m. Acceleration off the line is incredible, 5th and 6th gears are now great gears.

Upgrade your brakes before your tire size.

Which 38's and brakes?

Is the 5.38 gearing a diy swap? into the same axles? If not, what are we looking at for cost?

Thanks. And thanks on the brakes suggestion.

Did the brakes just fit or did you have to finesse them? I've heard it's a little difficult on previous posts about upgrading the brakes.

Don't forget a major tire size change will effect your speedo, shift points, etc. On our Jeep it was easy to adjust using an app. The older I get the harder it is to lift those big tires too.

Bronco's can only adjust up the the size of the 37x12.50 17 BFG K02 (Software hard limit by Ford).

So any 37 taller than the K02, or any 38+ will not be able to be fine tuned.

Most people running 38-40s don't care.

Full disclosure: I didn't read the entire thread, just replying to the original post.

I've been on 37's with the 2.3 since November 21 & have zero regrets. It's my daily driver & has been off-road plenty as well as multiday road trips. It's not fast but it's fast enough. Faster than my 16 JKU Rubicon on 35's.

The rim companies would need to post it, or ask someone who sells them. RTR, which I think has fairly light rims, doesn't seem to say what they weigh.

Method, though, does. For instance, this rim that works on the Bronco is 25lbs while the stock Sas rim is 35lbs.

I am also considering RTR wheels. And was also curious about weight. My personal preference is hubcentric and light weight when possible. Below is RTR’s email response from customer service.
