Largest tires on stock 3rd gen?

Hello All, I currently have a 98 3rd gen 4 runner with the extremely small 225/75-15 tires on it and would like to know the maximum size I can put on it with the stock suspension. I know I see the mention of 265/70-16 or 31x10.5-16 on the 6 cylinders, but wasnt sure if that is also with stock suspension 2 wheels drive 4 cylinders as well. Please help clear up the confusion. Thanks!

 

the 4 cyl and stock suspension shouldn't make any difference, id be willing to be a 265/70/16 or 265/75/16 is probably as big as you can go stock. you shouldn't also look into tall/skinny
