Try Tire Rack for the tires. Blizzaks are great in the snow if you're just looking for a dedicated snow tire and plan to switch out in the spring.
As for other recommendations, not much that I can think of. Those things are pretty well equipped as they are. Don't know what your budget it but rear DVD players are a nicety that have saved us on many trips in the past.
Well, this forum is still a bit slow. I'm not sure if it's because the 2011+ models are still somewhat in their infancy or if it's because they're so darn good that no one is coming on here to report problems.
Anyhow, Ford's accessories store is usually decent when it comes to stuff like the deflector but I'm not seeing anything for the Explorer. Auto Anything, Stylin' Trucks, Real Truck, and a few others generally stock a lot of aftermarket accessories for these things.
Hey there and welcome - didn't even know they had a 2011 and up forum
We too love the wife's new sport - right now all stock with 2400 miles on it so far....
She doesn't want me doing anything to it like I did with her Audi unless I have a signed release from her (but what I can sneak on there is a whole nother idea !)
I'm holding out for the amp powered steps since the sport is right in the middle of low enough to not need them but not as high as the limited's to really need them...
Really surprised the aftermarket hasn't started producing for the new Explorer's - not sure if the sales are not there or what, but we see them all over...
Let's see if we can get some activity going !
They are selling like hotcakes around here... in fact I've seen two other blondes driving tux black sports just like hers' in our lil town of Mansfield, Tx !!!
