Questions about rim/tire combo for an '84 c10

[KSTHANE]

Hi everyone,

I am new to the forum and am just now looking to make improvements to a truck I bought earlier this year. I am not a truck or vehicle expert in any way; I just grew up on a farm with trucks like this and now that I'm an adult I decided I wanted one. I bought this truck from an airport so it has been in a hangar for most of its life. As far as I can tell it was the most base model they sold that year and is probably totally stock.

I want to put some better wheels and tires on it but don't know how big it can actually accomodate without a lift kit. The bolt pattern is 5x127.

I'm sorry for this simple/stupid question, but can I buy 16 or 17 inch rims (I'm looking an Amazon.com for example, for wheels that "fit" my truck according to them) and some all season tires and expect them to actually fit in the wheel well? I'm really just looking for a much wider profile tire that is also wider circumference and fills the wheel well up a lot more.

Here are some pics of the truck from before I got it that show the current tires. Thanks in advance:
