im sure they would....might make ur tires stick out some with 3.75 of backspacing..lol...i wish i had those rims...im in the process of getting some 1 1/2 in. wheel spacers off of craigslist right now...that way maybe my truck will get dirty when i go muddin..its got 31"10.50 TSL's...on 15x7 in rims...idk what the backspacing is though...o well..anyways...now that i have rambled on...i think the rims will fit fine...

 

3.75inch is stock backspacing for your truck. So yes they will.
