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.
You've got a pretty standard road bike that comes stock with 25mm tires. The rims are less of a concern than the frame/fork/brake caliper clearance. I'd be surprised if you fit larger than a 28mm tire on there, maybe a 30mm if you're okay with some rub (which you shouldn't be okay with).
Don't bother getting new rims/wheels for this bike, it won't change clearance issues (and the 200+ price of any decent wheelset is gonna be a lot better toward a new ride). Try finding some 28mm gravel-style tires, or a different bike.
