look in the owner's manual- sometimes there's a sticker in the glovebox or on a door pillar- it is splitting hairs between these two you mention- if those wider tires aren't rubbing, then they will give better traction on dry pavement, but the skinnier tires will work better in the snow- having smaller tires (70) might throw the speedo off a mile or two- that's the only difference- so if they are good tires, and you're not driving in snow, they should be fine- having said that, if you have the money go ahead and put some Michelins on that thing in the factory recommended size-

Thank you so much


Also look on the driver's door post for a small square sticker. It will list the proper sized tire for that particular vehicle.
