So I'll be tire shopping soon!

I'm confused by a few things I've read in my research.

Of course I read this thread.
https://www.tundras.com/threads/largest-tire-you-can-run-stock-for-all-generations.9762/

Which says I can run up to 285/65R18 with out a lift. I'm sitting on these rims. And will be installing TRD OR yellow and blue takeoffs from another forum member.


But then I read in this thread
https://www.tundras.com/threads/what-lift-is-good-enough.42740/page-2
Post 38 a forum member says he is running 275/70r18 on stock suspension.
This thread also has plenty of members running 275/70r18 on stock suspension.
https://www.tundras.com/threads/can-i-see-your-275-70r18-please.16553/

Does the first thread need updating? Or am I missing something obvious here?

 

I had 275/70/18 on my truck before the lift. Fits totally fine. It same width but 1 inch taller. Turn your wheel and look at both tires, if it has more than half inch of clearance it is good to go
