Limited 4runner tire size

What is the largest tire I can fit on a stock height 5 gen Limited with the factory 20” rims?

 

Don't recall the source but many forum members have referred to this chart. Hope this helps.

This is awesome! Thank you!

 

Cool. Appears some have said they need to slightly clear the liner with the 275/55/20s as there may be slight rubbing with full lock in reverse. If so you can use a heat gun to soften the liner and gently move/push it out of the way.
I have a 2018 Limited and will likely go to 275/55/20s when my originals wear out in a few thousands miles. Many more tire options in that size versus the stock size and I want a bit more aggressive thread.

 

The dealer had installed 265/60-20's on my '19. Slight liner rubbing in reverse at full lock.

 

Someone on another forum put that together, it's a very helpful resource
