Do you think I can fit 38mm tires on my bike? (self.bikewrench)

Here's the bike I have: https://www.bikesdirect.com/products/motobecane/mirage_tour.htm

Here's the tires I want: https://www.amazon.com/gp/product/B0B6BXF43T/ref=ox_sc_act_title_2?smid=A3QGN5CVWB8NQ6&psc=1

I recently moved and there's less paved trails and more rail trails. I want a wider tire, but can't figure out if it will fit on the rim, within the fork/frame, or within the brake pads. I measured and 38mm looks like it should fit, but I figured someone else might know more than me. All the products and stats are listed on the site.

Also: I get it, it's not the best bike/tire combo on the market. Cycling is only really a side hobby for me, so don't shame my choices. I love my bike and the price I paid for it.

I'm definitely not an expert but I would say you need at least a few mm (maybe 5mm) of clearance on each side. A bike frame is not static while you ride it.

Ok, that's a good base to go off of. Would the tire fit the rim, you think?

Not sure about that one. Afaik, the manufacturer of the tire should tell you what rims it fits.
