No I was shocked how good it looks and rides stock no rubbing whatsoever

Hell yeah, take a hit on MPG?

Honestly, I’m not 100% sure I only had the 35s on for about a week. I went with these because they’re some of the lightest 37s on the market, and they’re brand new tech-wise (just released in 2025).

MPG in this truck is already pretty rough, it probably dropped another 2 mpg with the 37s. I’m filling up about once a week. But let’s be honest it looks absolutely badass, so that’s the trade-off.

What does the computer say mpg wise?

What color is that on the beauty ring? Any issues balancing the KO3s?

No balancing issues whatsoever. Ride quality feels nearly identical to stock. There might be a slight increase in steering and braking effort, but it’s very minor. I had the wheel powder coated satin black and made the ring a dark gunmetal for contrast.

Here are a few more pics I honestly love the fitment stock which I thought I wouldn’t so I probably won’t be adding springs anytime soon.

I think the contrast looks great.
These trucks were clearly designed for 37s and I won't be doing springs until I move up to a 38 or 40.

Facts I’m not sure why ram doesn’t offer it

2-3mpg loss you say! Shit I’m already only getting 10-11mpg. 2-3 more and I’ll be at trx numbers.

The truck honestly looks pretty level here, is it the angle or would you agree? Looks really good.

No it definitely looks level I never walk out to it and think that it needs to be.

I’m looking to go the same route and really don’t want to do any aftermarket suspension alterations so this is great info, I think you already mentioned you have jumped or flexed the truck out a bit with no running issues? Also do you intend on having the dealer recalibrate or do you have any issues with parking sensors?

I don’t think it needs any recalibration. The park sensors and drive assist are working perfectly. I’m sure the speedo is probably off a little, but I’m in Texas where speed limits are more of a suggestion anyway

TRX park sensors disabled with 37’s. They never found a fix, not even Tazer.

I think it is safe to say the new TRX won't have that problem since the issue has been corrected in the RHO platform.

TRX? Wtf is a TRX?
