The rubbing issue is also affected by height of the tire. If you go too big it will rub no matter how narrow you go. Eventually you fill the wheel well and they rub. And I have the NITTO terra grapplers like many others on this forum ( I believe I was the first ) and they are awesome.The 18" tires are quite a bit more than the 16" tires. Not thread jacking just getting my opinion in. And again they look great. shawn
