I had the WR G3 on my Mazda CX5 and loved them. I will probably go with the newer G4 but I am wondering if the larger 265 will fit the ridgeline. I am assuming from your post the 255 do not rub, yet do you think that I could get away with another size up?The Nokians WR SUVs are my favorite tires having had one set of G3s and two sets of G4s on a couple of Honda SUVs. I think if you don't plan on running chains and you stay with the stock wheel or a wheel with stock specs you should be ok. I have the 255/60-18 WR SUV G4 on my 2019 right now because I didn't want to deal with any fitment issues and I was traveling to Minnesota in the Winter for a family emergency.
