34" tires on stock - THEY FIT

[LightningSauce]

Just had Toyo ATIII EVs (275/65r20) installed on my stock '23 Lighting Lariat (Max Tow). Replaced OE tires (275/60r20). The new sized tires fit without a lift or leveling kit. Pictures below...

Looks good! What kind of drop in efficiency have you seen so far?

Not sure yet...just had them installed today and drove ~8 miles home.

Following. Curious, how many miles did you get out of the Hancook’s?

Interested - hope you post the net results for everyone here.
I myself am interested in options for next winter, will run the factory set until next fall, then switch to a more suitable winter tire.

They look great!

Any rubbing? How's noise compared to stock?

Still running factory Hankooks at 30K miles. Looking at replacement around next fall which will bring me around 45K. Id love to hear your thoughts and observations on these.

Additional notes/responses :

OE tire miles : ~15,000 miles; Tread was still great all around.​

Rubbing : none that I know of; plan to make a video of wheel range to ensure​

Efficiency : to be determined;​

Noise : did not notice anything outrageous and I drove home with the radio off.​

Pressure : 41 psi (new and old tires)​

​

Since I purchased the truck, i wanted to beef up the wheels...so I waited ~2 years to replace them. I work from home, so my annual miles are limited. As I drive more, I will update the thread with efficiency numbers.

I got rid of my Hankooks at 36k because of uneven wear (caused by the front end).

Do you know what was causing the uneven wear?

 

[roddiaz1]

I was unable to get to the bottom of it, but my guess it is camber/caster issue.

I got about 40k on my Hankook’s but they were BADLY worn on the inner and outer edges. My daily commute has several roundabouts but I felt they still wore quite badly along the perimeter.

I have about 6k on the LT275/60R-20 TOYO OPEN COUNTRY A/T III EV E and I love them. The look, feel, and lower than expected road noise. I believe when I bought them back in October 2024 they only had the load E version?

Range is probably a tick lower but didn’t benchmark old vs new.

I think I need to increase pressure though. At 36 psi, they look a little low. Do we have a published psi from Toyo or Ford on these Load E tires?

At what intervals did you have the tires rotated?

 

[roddiaz1]

At what intervals did you have the tires rotated?

About every 10k miles. (wouldn't have the patience to do it any more than frequent than that). My other vehicles get rotated every 20k or 25k without issues.

Yeah for those that aren’t aware the outer edge wearing poorly on the factory hankooks is widespread. Doesn’t matter how much you rotate. They don’t sell them with those anymore for a reason.
