BFGoodrich KO2 285/60/20

[YELOSUB]

It’s been awhile since I’ve posted but my truck needed new tires at 25k miles, the stock 20” tires suck on the 2021 Ram Night Edition. Anyways, after a ton of research I finally decided to go with a 2” front leveling kit by Daystar and went with the BFGoodrich KO2’s in 285/60/20 on my stock 20” Night Edition rims. Man I couldn’t be any happier, it has totally changed the look and feel of the truck. Truck sits level now with the back and I have ZERO rubbing anywhere. If you are considering doing a 2” level kit, go with the 285/60/20. Love the KO’s and don’t notice any more road noise than stock. And my speedometer is only off by 1 mph at 75 mph. Here are some pics:

Nice truck, tires look great!!
Technically, going from 275/55/20 to 285/60/20 your speedo should be off by about 3.5 mph at 75mph.
Here is a link that shows it:

275/55-R20 vs 285/60-R20 Tire Comparison - Tire Size Calculator | Tacoma World

285/60-R20 tires are 1.56 inches (39.5 mm) larger in diameter than 275/55-R20 tires and the speedometer difference is 4.6%

Don't worry about it dude. I put 35's on mine and I'm off by 2 or 3. I just don't happen to give a crap as long as I'm in the neighborhood. I drive pretty fast anyway.

You are correct. OEM -2+3.5=~1 mph.
