Hey there. I am not new to the dodge forum, but am a new member. I have been following the forum for several years now. I currently drive a 99 Ram 2500 5.9, but am in the process of selling it and acquiring a 2000 Durango as its replacement (the twins dont fit very well in a single cab truck, and the wife would have to ride in the back!).

 

I have a 99 Dakota which came with 31-10.5-15. They are hard to find and are expensive.
p215/75r15 is a size also shown for this truck. They are much more reasonable in price but would they fit on the same rims? Congratulations on the twins though. Doubt it would be a good idea to put Mama in the back......
