Tire size

[attacksoldier]

Have a question. My dakota came with 215/75-15's on it but the spare tire is a 255/65-15. A friend of mine that works in a tire place says there are like 3 different sizes I can use for my truck but I can't find anything in the owner's manual. He told me 215/75-15, 235/75-15, and 255/65-15. Which one would work best for the truck?

I'm guessing you got this car used, as I can't imagine the vehicle coming with the larger tire as a spare - seems like an additional and unnecessary expense for the manufacturer.

First, check the vehicle placard for the original tire size and inflation pressure. Some vehicle manufacturers list all the tires optioned and some the specific size that came on the vehicle - I forget what Dodge does.

Assuming there is only one size listed, whatever is listed on the placard would be the best. The shocks, springs, and sway bars were set up for that combination.

If multiple sizes are listed, see if the dealer can run the VIN and tell you what the original tire size was.

255/65-15 will offer the best handling
