Tires: rims/tires, tire placard, winter tires

Question
my husband bought rims for my winter tires on my  dodge durango.
He said that they are 7 inch instead of 8 inch. Will these work and will I need a different size tire than what is on htere now?

Answer
Donna,

Yes, they will probably work, but there is an awful lot of stuff that has to be considered.

First is what tire size is listed on the vehicle tire placard?  

On every vehicle sold in the US – and I am told this is worldwide, but I have not been able to verify this - there is a sticker – commonly called the tire placard - that lists the original tire size and the proper pressure for that size.  The placard is usually located on a doorpost or in the glove box – but sometimes it is located in the trunk or on the fuel filler door.

BTW, it doesn't matter who makes the tire or what pressure is listed on the tire's sidewall, if the tire size is the same as the placard, then the pressure listed on placard is also appropriate.
