I recently purchased a used 4runner with Nitto Ridge Grapplers. I am disappointed with their performance in wet conditions and am looking for alternative aggressive looking AT tires. But, I have never had this type of tire before, so I dont know what I should expect for wet traction. I am used to Michelin Defenders which have never let me down in the rain. Is something like a Wildpeak AT3W going to be a big improvement over the Nittos, or is it a marginal improvement? If it is marginal, I dont think I want to spend the money as the Nittos have a lot of tread left.
