    Those are quite a bit smaller than your factory tires. Maine law prohibits putting an inspection sticker on your truck with that size tires one it. Besides, it's not safe. You will actually be riding on the sidewall because they are too thin for the factory rims.

    thanks, the thing is, they are not stock rims. and i dont quite get why i would be riding on the side wall anyhow. 16 " tires fit on 16 " rims right?

    What he's saying is, when you mount the skinny tires on your wider rims it pulls the bead out to the rim which will cause the tires to grind off the edge of the tread at the sidewall.

    Sell the tires and buy some that fit.

    I don't know what size rims you have now, but a 1995 1500 would have come with 225 75 16 tires on it. Skinny tires work much better for plowing than fat ones.

    The two wheel drives could of possibly had that size. If he was running 265's, the rims are probably at least 7.5 inches wide, too wide for the 225's.

    Do me a favor. Open the drivers side door and look at the stickers on the rear edge. What is the tire size stated on the sticker? What is the load rating?

    Also, look at the rim and see if you can see any numbers stamped. what exactly are those numbers? It will probably indicate 16 x 7.5 or 16 x 8.

    I'd say you could run 245 75 16, but I wouldn't go skinnier if it were my truck.

    I run 245 "snow tires" in winter, and 265 all seasons in summer on my 2500.

    Then you cant legally run those 225's in maine, nor would I want to on those rims.

    LT235-85R16's would be the smallest I would go. Because they are tall, you can still run them legally. And because they are skinny, a studded set absolutely rips through the snow and ice.

    Good luck finding someone to install them. There aren't many places that will install tires that aren't with in the legal range for size. I know a shop up here that probably would. But I would never let him touch one of my vehicles any ways.
