BF Goodrich AT K03 GEN 3 Limited TRD 2023

Help Needed: KO3 275/65/R20 on Stock TRD Suspension - Conflicting Information
I need help with tire fitment for my TRD. My OEM tire is 265/60/R20, and I need to replace ASAP.

Discount Tire (visited twice) claims AT KO3 275/65/R20 would rub on my stock TRD suspension. However, I've seen multiple forum members running this exact setup with no modifications and reporting no rubbing issues.

I've used KO2 tires on my previous trucks for years with great performance in tough terrain throughout Colorado and Utah. The KO3 seems like an upgrade I'd prefer to make.
Looking for confirmation from anyone running 275/65/R20 KO3s on stock suspension. Am I wasting time and need to settle for smaller tires or add a lift/leveling kit?
Getting inconsistent answers from Discount Tire and need reliable information.
Thanks for any help or opinions!

 

you have the answer : "However, I've seen multiple forum members running this exact setup with no modifications and reporting no rubbing issues."

 

They will fit. I have Nitto Terra Grappler G3s and ran them for a week stock height. I've since leveled and will be also swapping for new wheels/tires.

 

How did it turn out?

 

While my budget has been tight recently, I'm still planning to make the switch I discussed. I've been trying to extend my current tires until camping season begins, but recognize the importance of having proper tires for Colorado's conditions. I noticed Discount Tire down the street is currently slammed with winter-to-summer tire changeovers, which is expected this time of year. They've always handled my rotations and fixed issues effectively in the past. Once my finances stabilize a bit more, I'm committed to completing this tire upgrade before heading into camping season and will let you know. Thanks
