ok so i found this nice set of rims that are 16x10 moto metal 951s(my truck is black, black chrome, NICE HAHA)...i have the stock regular ones(not trd) with just 245/75/r16 tires and i wanted to go up to the 265/70/r16 tires because they have like white writing and they look kind of better(i think they come on the stock trds). what i was wondering is are the stock ones or the other ones i mentioned the right size for the rims? and will i have to get balancing and other stuff done when i get them installed, if yes how much for installation and all? also what i notice is that i went from a 75 to a 70 on the second number, what is that? actually what do all those numbers mean haha i know that the 16 is the rim size but what are the other ones.
sorry about all the questions but im new to this
