Will these different sized tires fit?

[PoPo8]

Hello

I have found a good set of tires for a cheap price. But I am ignorant when it comes to tires and I am not familiar with the tire numbers. I am not sure if they will fit or not and what the difference is.

I currently have 295/75 16 tires on my 2001 F350 4x4 with stock rims and no lift.

The tires I have found are 305/70 16.

Will these other tires work???? or will I need spacing and if so I do I go about that.

Remember I am completing ignorant. If you can explain the number system as well that would be great!.

Thanks

Metric To Inches Tire Size Conversion

Go there and plug in the numbers for the tire sizes and rims...make sure you hit reset when you put in a new tire size after you have calculated one already. It will tell you in standard sizing

i know i fit my 315/75/r16s on my truck but mine is leveled. Only think is at a full turn it rubs on the leaf springs. I have mine forsale right now just beacuse I want 20's or money. Other than that I like them.
