I have just purchased a new-to-me 2009 GX470 with 39,000 original miles. At dealer now for full fluids swap, TB,WP, belts and CV boots just to baseline as the car is 11years old. The dealer put on 4 new tires - Dunlop AT20 265/65/17. I see that the feedback on these tires is horrible. What would you replace them with on stock suspension. Mostly highway/street use, but I WOULD LIKE to take it on trails and perhaps even to the mountains/light snow occasionally! What are your recommendations? Looking for safety and cost is not my primary driver, dependability is. Would Faulkins AT3 work and still be quite on the road? Any input is appreciated!!
