The Limited I ordered comes with 255/50R20 tires. I will be using the 245/65R17 winter tires from my present vehicle, which came with stock 19" tires, on Ford's base 17" steelies. The difference is speedo reading will be 1.689% too fast or 1 mph at 60. Narrower tires are better in snow. In any case, stock all-seasons will not match dedicated winter tires for traction in snow or on cold bare pavement. Different rubber compounds! Also, my insurance company gives a 5% discount on my insurance because of the use of winter tires.I think the overall tire diameter between 17,18 and 20" wheels are roughly the same- if not, changing between those sizes can greatly effect everything about the vehicle's performance. Not to mention the speedometer error.
20" wheels do look cool though.
Currently only the province of Quebec has a mandatory winter tire policy. It applies to all vehicles registered there. Not sure what tires come on the 2011. Have seen pictures with Hankook but I'm not sure if they come all the models.I thought in one providence (or maybe just a city) in Canada, winter tires were mandatory. Don't remember which one.
I have run dedicated winter tires on my cars for the passed 5 or so winters. This winter with my Explorer will be the first I haven't- although these tires do carry the mountain snow flake symbol, but they still leave a little to be desired as far as snow stopping traction.......
I think the Hankook must be made just for the dealer ordered Explorers. I looked at pictures of the wheels and see the tire shows as a Hankook Optima. When I searched that particular tire on various sites, it does not appear to come in the size that the Explorer Limited uses. Had the same problem with my Highlander. It came with Toyo A20 in a 19" size but I could not find them on Toyo's website. Many complaints about them not lasting very long as is typical on new vehicles. The tires that come on thenm seem to be for comfort and quietness. Not durability. Probably the same with the OEM Hankooks.Limiteds get Hankooks, XLTs get Michelins, not sure what the base model gets. Suppose I should have looked the other day, local dealer got their first 2011 in, base model for a fleet/company.
