Mounain bike tires on a roadbike?

I have this Schwinn, dual sport bike they call it, 700c, I'm wondering if it's possible to put some mountain bike tires on this thing, I looked around and it seems to be a major hassle if not impossible to get mountain bike tires to fit the rim already on it but could I order another set of like 29" rims and just swap them out if I wanted to? I do want to get a real mountain bike but I'm saving for something nice, just wondering if in the mean time there are any alternatives. This guy here: 700c Schwinn Men's Hybrid DSB Dual Sport Bike - Walmart.com Thanks for any info!

Swapping rims is a pretty involved process. It's basically akin to building a new wheel. Some details here:


The most practical short term solution might be to figure out what kinds of tires you can fit on your existing rims. You might be surprised.

Tire Sizing Systems

Note that 700c and "29er" refer to the same diameter. With a bit of research, you might be able to come up with a satisfactory compromise that doesn't involve a lot of expense or tools.

Look for cyclocross (CX) tires. The skinniest I found were Kenda Kwicks, which were labeled 30mm, but were actually a little skinnier. I managed to jam them into a Trek 660 for my first season of CX. They're not great tires, but work pretty well for hard pack dirt and gravel. And they are cheap.

I run knobby 700c tires on one of my bikes sometimes, there are definitely some out there. That's your best bet imo, OP.

There are two practival issues to consider:
1. Do the brake calipers and/or fork provide enough clearance?
2. What will be the impact of a wide tire on a narrow rim for fitment and safety?

700c and "29 inch" mountain bike tires have the same bead diameter, so they're generally interchangeable, but you'd need to watch out for two things:
  • Do your frame and fork have enough clearance? If you put a wider (and taller) tire on, will it rub the frame? The brakes? The fork? You can measure the narrowest clearance your bike currently has and estimate how much bigger you can go.
  • How wide a tire can your rims take? You don't want to run a tire that's too much wider than your rims. Sheldon Brown (and others) have a chart that recommends tire/rim width combinations:
    Tire Sizing Systems

caloso's recommendation for cyclocross tires is probably your safest bet. If mountain bike tires are too wide, you can find knobby cyclocross tires in somewhat narrower widths.

The limit will be what will fit between the frame tubes in the back. Listen to @caloso and find cyclocross or "gravel" tires. Here are some examples from a company I like 700C Tires | WTB. Don't overthink it, you don't need to change your wheels at all, and there are plenty of options.

I think your bike with some knobby tires will work well for dirt roads and paths. Will be sub optimal on real singletrack though.
