Will going up to bigger width and height affect transmission in the long run?

Hello, just recently got a 2023 Limited Crewmax and looking into getting A/T tires. Stock’s are 265/60/20 and been looking at the KO2s in 275/65/20 for that added height and width. Do you guys think it’s too big of a bump up to cause transmission issues?

 

No

 

That's not a huge jump in tire size, unlike say a 37" tire, which in day to day driving wouldn't be bad but if you were to tow and you had much larger tires it could affect the tranny depending on how it was driven.

 

Thank you guys!

 

If that small bump up in tire caused a tranny issue then almost all of us would be in trouble. Go for it.

 

I ran 295/70/18's on my 2nd gen for over 10 years/200k miles and there was no issues with the tranny. You have nothing to worry about.
