275/65/20 - Looking For Your Input…

[Thunder Buddy]

Hello There - I’m hoping some of you could help chime in on your experience/feedback.
I’m on the fence of upgrading from my stock Goodyear Trailrunner AT (275/60/20) to the Goodyear UltraTerrain 275/65/20.
Looking for feedback on this:
1. Has it had a major effect on your MPG (40lb stock tire to 57lb Ultraterrain)?
2. Do you notice that the tires ride a lot worse (going from a SL to E Load range)?
3. Lastly, I’m assuming there is no fix for the speedometer and it’s reading a bit low on the highway?

Thanks folks for your input.

I like those tires..... and no the dealer isn't any help with the speedo!

Hopefully an updated Hypertech comes out soon.

I just put that size on my SLT with a 1 1/2 level and my gas mileage hasn’t really changed. I put them on at 300 miles. I went with Toyo at3.

So I ended up just pulling the trigger. I’m pleasantly surprised that the ride from the SL to the E Load Rating is hardly noticeable. They have just a touch more noise.
So far so good.

I just put on Michelin LTX Platinum LT 275/65R20 Load E on my 2020, very happy with it. I will test out mileage next week with 10hr drive to Ohio.

Michelin’s rarely disappoint! Very good tire!
Sorry you have to go to Ohio; Go Blue!
OK, OK, I will stop being a jerk - Haaaaa.

Do you have a level kit on? Is there any rubbing? My AT4 came with the 18’s and 32’s. Just wondering if I go up to a 33 or 34 if there will be rubbing without a level. Currently running method 305’s with a -12 offset as well

Truck is 100% stock and I plan to leave it that way, which is why I debated on tires for so long. It’s absolutely perfect and they do not rub anywhere. The problems arise when you change out the offset, as I have read about with other folks putting on new wheels. This is only 1” taller than the stock 33” tire. Not to mention I’m impressed with the tires - they have done very well in the snow we have had here for the past 2 days.

Any chance you could post a photo of these on your truck? Considering the same.
