I'm running 32's on stock axles now. I wanna go to 33's. We're taking a 1000 mile road trip next month for Christmas. Do you think I should get the new 33's before the trip? Is a long road trip with the 33's recommended? We've done the trip before with my current setup but I need some tires soon. Thanks

You'll probably notice reduced MPG and power with the bigger tires, but they won't *hurt* anything. If your current tires are low on tread I'd replace them before your trip, especially with it being winter...
