Please help with tire and wheel fitment
I need help from all the tire and wheel guru's. I have an '06 F250 Superduty crew cab FX4 PSD that is totally stock. I have an opportunity to buy a nearly brand new set of 305/65/18 tires for an awesome price. It sure looks like they will fit, but can anyone tell me if they will for sure? Also what size rim would be better, 18x9 or 18x10, and what offset will I need to make this work (if possible)?
The factory rims are 17x7.5 with a +40 offset and the tires are 265/70/17.
One local tire place said they would work fine but said I needed a -12 offset. This seemed odd to me since the factory wheels have a +40 offset, but I'm not to knowledgable in this area. Please offer advice.
Thanks for the help.
