Living in Colorado with snow and great trails realizing I'm going to need to get some all terrains for my 2017 altitude with 18's. Finding I'm incredibly limited in my options... So I've narrowed it down to 2 tires both are 29"... 1. BFGoodrich Ko2 255/55r18 Pro's: 3 peak mountain snowflake rated Tried and true Con's: Price $215 a tire Weight! 45lb tire thats 20lbs over stock 2. Atturo Trail Blade X/T 235/65r18 Pro's: Aggressive tread Price ($140) Weight 30lbs only 5lbs over stock tire Con's: Very new (atturo made by continental) Not winter rated (does have siping) Will be on stock 18" wheels with 1" or 1.25" wheel spacers. No lift yet, but considering the ATP in the future. Let me know your experiences with either tire!
