I run 35x12.50x18 on my bone stock no problem.

I am running 315/70r17 KM3’s on mine.

You can run 35's no problem.

What year is your truck. I have a 2020 running 35's on stock suspension

I'm still running stock tires on mine, but thinking about going to 35's the next time.

I know this is older but here are some Cooper STT Pro's 305/70r18 with Raceline Gauge 950B 18x9 +18 on my 2016 3500. It has a 2.5" leveling kit.

Good looking truck. How do you like those Cooper Discoverer STT pros. I am thinking about putting them on my 2019 Megacab.

Thank You! I have only had them for a day. I have had Cooper Tires in the past that wore like iron. My buddy has the AT3 XLT on his '15 Cummins and loves them. I will say they are louder than my other tires but that is to be expected with a more aggressive tire. The guy at Discount showed me his 2003 F350 with them on it claiming to get 60k out of them with 5k interval rotations and proper inflation and is on his 4th set. I like the look, I like the size I put on and I like that they are made in the U.S.

Guy at work told he got 60K out of his first set on a power wagon and my neighbor is on his second set and he said 60K miles also on a F-250 running 37's. I like the way they look and reviews are solid. I like they are made is U.S. also.

Which tires are you running? You mind posting a pic. I'd like to run 35x12.5x20 stock but was worried about rubbing.

I’m running 285/70/17 on my 2012 and have plenty of room to go 305.

The 2014+ truck sit higher than mine when stock.

As to tires, I’m currently running Toyo AT2 extremes and hate them. They are downright dangerous on wet pavement.

Just talked to Discount. They told me a 295/70 will impact my speedometer up to 5 mph. Is this right?

Any time you go larger diameter tire your speedometer will no longer be calibrated.

My stock size tires were 265/70/17 and I had to recalibrate 2 mph when I upsized to 285/70/17.
