For a 700c commuter with room for a 37 mm tire, Schwalbe Marathon Plus is our protection-focused pick. For a road-bike commute that calls for a narrower 25 mm tire, the folding Continental Gatorskin two-pack is the more relevant choice. Both selections have a 622 mm bead-seat diameter and require inner tubes; neither is a universal replacement for every commuter wheel.
Start with the ETRTO/ISO numbers on your existing tire and the bike and rim makers’ permitted combinations. In 37-622, 37 is the nominal width in millimeters and 622 is the tire’s inner diameter, which must match the rim’s bead-seat diameter. Matching 622 is only the first check: approved rim width, tire type and clearance at the frame, fork, brakes and fenders still matter.
Best commuter bike tires at a glance
| Selected tire | Best fit | Construction | Main tradeoff |
|---|---|---|---|
| Schwalbe Marathon Plus, 37-622 / 700x35C; one tire | A compatible city or hybrid commuter prioritizing a substantial protection belt | Wired bead, tube type; 5 mm SmartGuard layer | Needs room for nominal 37 mm width; flats remain possible |
| Continental Gatorskin, 25-622 / 700x25C; two folding tires | A compatible narrower road-bike setup used for commuting | Folding clincher, inner tube required; PolyX Breaker and DuraSkin | A 25 mm size does not suit every modern rim or rough-route preference |
1. Schwalbe Marathon Plus: best protection-focused option
Choose the Marathon Plus 11100769 when your bicycle permits its 37-622 size and your priority is a thick puncture-protection layer. This exact Black+Reflex version uses a wired bead and an inner tube. Schwalbe also labels it 700x35C: that familiar name should not override the more precise 37-622 marking when checking fit.
Pros: the 5 mm SmartGuard layer is a concrete reason to choose this model, and the selected size has Schwalbe’s E-50 designation. Cons: the maker lists approximately 900 g per tire, so it is a substantial choice if wheel weight matters. Its rigid bead does not fold for compact storage.
Do not take the brand’s “flat-less” wording as a guarantee. Schwalbe explicitly says a flat can still happen and recommends setting pressure with a gauge because squeezing the tire is unreliable with this construction. Carry repair equipment even with a protection-focused tire.

2. Continental Gatorskin: best narrow road-bike option
The selected Gatorskin pack contains two folding 700x25C tires, ISO 25-622, for use with inner tubes. It makes sense for a road commuter whose approved setup uses that narrow size and who wants to replace both tires or keep a spare. It is not a tubeless tire, and “folding” describes the bead construction rather than permission to run without tubes.
Pros: Continental documents a woven polyester PolyX Breaker beneath the tread and a polyamide DuraSkin layer protecting the casing. The folding construction is convenient to store. Cons: this is a two-tire purchase, and the selected 25 mm width limits its appeal if you want a wider tire for your route. Check compatibility before downsizing from a wider tire.
Continental’s Gatorskin documentation describes protection features, but those are not proof of immunity to flats or a measured advantage on your commute. Choose by the bike’s permitted dimensions and your riding needs; this comparison does not establish which tire is fastest or grippiest.
How to choose a commuter tire that actually fits
Read the complete size code. A tire marked 622 will not fit a 630 mm rim just because both are associated with road bikes. Likewise, “26-inch” can refer to several different bead-seat diameters. If your current tire is 559, 584, 590 or 630 rather than 622, neither exact selection above is the right diameter.
Use the bike maker’s clearance requirements and the rim maker’s width range. Schwalbe’s sizing guidance explains that mounted width changes with rim width and inflation, and a newly fitted tire can expand. Do not assume a nominally narrower tire clears every brake or fender, or choose a larger one based only on a gap measured before inflation.
These two exact selections are tube-type clinchers. Choose an inner tube whose stated diameter and width range cover the tire, with a valve type and length compatible with the rim. Do not convert these models to tubeless, or assume inserting a tube makes a non-approved hookless combination acceptable. Ask the tire and wheel manufacturers if the permitted combination is unclear.
Follow the tire’s current sidewall or packaging limits together with the wheel maker’s instructions, using the lower maximum where they differ. Continental’s mounting guidance makes that limit explicit. An internet pressure recommendation for a similarly named tire should not replace instructions for your size, rim and load.
Frequently asked questions
Does 700x35C mean the tire is exactly 35 mm wide?
No. The selected Marathon Plus is marked both 700x35C and 37-622. Use its ETRTO size for identification, then check actual mounted clearance; rim width and inflation affect the final dimensions.
Can either tire be used on a hookless rim?
Do not assume so. These are tube-type selections, and Schwalbe’s guidance restricts hookless rims to compatible TLE/TLR tires while also requiring wheel-maker approval. An inner tube does not remove the need for an approved tire-and-rim combination.
Will a puncture-protection tire eliminate flats?
No. Even Schwalbe’s Marathon Plus guidance rules out a never-flat guarantee. Protection features are a buying consideration, not a reason to leave your repair supplies at home.
Does the Gatorskin listing include two tires?
Yes. The exact selection linked here is the 700x25C folding two-pack. Other listings or size choices may have different quantities or bead types, so recheck those details before ordering.
Can I use the same tire on an e-bike?
Check the bicycle maker’s requirements for your speed class, load and tire size. The selected Marathon Plus carries E-50 on its manufacturer page. That designation is not a blanket approval for every e-bike, rim or load, and it does not transfer to the Gatorskin selection.
