Just reread the post 34 - I agree, that tire size does not even come up in the tirerack as a common winter tire available. and when you do a google search just for the size, mainly the Dunlops show up, telling me that Dunlop is one of a very very few manufacturers who make that size. So, I wonder, if the dealer tried to sell a set of more expensive tires to the fellow... however, once those tires are worn out of specs, i can always buy the 255s for the same set of wheels... Right?
265 refers to width of a tire, as opposed to my previous statement of the diameter. so, the tire is is by 10mm wider than 255... however, i could not find any article that would recommend for or against such a "swap". I am leaning closer and closer to buying that set - unless somebody here yells at me STOP, DONT GET MARRIE... ooops... DONT BUY IT!!!
