i have been to twenty differant tire shops and i keep hearing the same thing youre tire size is new to the market.and there is only afew tires you can buy for 18 inch rims.with out spending 350+ a tire this really me off but when i bought the truck two months back i didnt think about it,untill i used my truck as a 4x4 in the snow and found out that the stock bf rugged are crap and i wanted somthing with a little more go in the snow.all the tire shops say that 18 inch wheels are becoming more popular then before.and the tire companys cant keep up with the car manufactors.i guess all wait and see.
