Product Information
Full details
The Michelin City'J is a purpose-built tire designed for young urban cyclists who need a dependable and safe ride through city streets. Featuring a robust wire bead and a durable gumwall sidewall, this tire offers excellent stability and grip, even on wet pavement. While it provides exceptional strength for daily commutes and recreational riding, it is specifically sized for 20-inch wheels, meaning it is not suitable for larger adult bicycles or mountain bikes requiring wider treads.

Extended Product Information
FAQs
Will this tire fit my mountain bike?
This tire is designed specifically for 20 x 1.375 wheels. It will not fit standard 26, 27.5, or 29-inch mountain bike wheels.
What does 37-451 mean?
This is the ETRTO size: 37mm is the approximate tire width, and 451mm is the tire's inner diameter.
Is this a tubeless-ready tire?
No, this tire is designed for use with a standard inner tube.
Can I use this tire for trail riding?
The City'J is optimized for urban pavement. While it is durable, it does not have the tread patterns necessary for grip on dirt, mud, or loose trails.
How often should I replace these tires?
Replace them if the tread depth is significantly worn, if the rubber shows dry-rot cracking, or if the casing fibers become visible.
Troubleshooting
Difficulty mounting the tire on the rim
Ensure the wire bead is fully seated in the center channel of the rim before moving to the edges; use tire levers carefully to avoid damaging the bead.
Tire feels sluggish or rolls slowly
Check your tire pressure; under-inflated tires increase rolling resistance significantly.
Frequent punctures
Inspect the inside of the rim for sharp spoke ends and ensure the rim tape is properly positioned.

Setup, Compatibility & Care
Before installation, ensure your rim matches the ETRTO 37-451 sizing requirements. To install, use standard tire levers to seat the wire bead firmly into the rim bed, making sure the inner tube is not pinched during the process. Inflate to the manufacturer-recommended pressure indicated on the tire sidewall. For maintenance, regularly inspect the tread for embedded debris like glass or sharp stones and wipe the gumwall sidewalls with a damp cloth periodically to maintain material integrity.
