So with a more aggressive tire tread like that, do you sacrifice a lot of on road performance? I understand they won't grip like a Z-rated performance tire, but I also don't think any of us drive our FJ like a Porche 911 either. I just wanna make sure I won't be putting my life ,or more importantly my 22 month old daughter's life, in jeopardy by going to a tire designed more for offroad use on a daily driven car. Thanks!!!
