Heidenau Modern Street Motorcycle Tire | Honda CB350 / CL350 / CB360 / CB450 / CB550 / CB750
You don't have to run vintage-style tires on a vintage Honda. The Heidenau Modern Street puts a modern tread pattern and modern rubber compound on your classic bike — in sizes that actually fit inside the fenders, between the forks, and swingarm without modification. German-made, "H" speed rated, and built to handle real miles.
Why You Need This
If you want maximum handling performance from your CB350, CB360, CB450, CB550 & CB750, the Modern Street is the tire to run. Where the Vintage Street and Vintage Scrambler prioritize period-correct looks, the Modern Street prioritizes grip and road feel. The wider tread contact patch, contoured profile and modern sticky compound keep the bike planted through corners and will eat up highway miles.
Heidenau has been making tires in Germany for over 70 years, specializing in motorcycle and scooter tires. We have done the work to figure out which modern metric sizes fit vintage Honda frames — so you get a modern tire that bolts right on without fender or clearance modifications.
These tires are tubeless by construction, meaning they'll fit modern one-piece rims. Since most vintage Hondas use spoke wheels, you'll need to run tubes and rim strips inside them — which is perfectly fine. Running a tube inside a tubeless tire is standard practice on spoke rims.

Modern Metric Sizes vs Original Honda Sizes
Honda specified tire sizes in the old inch-based system (i.e., 3.00-18, 3.50-18). The Heidenau Modern Street uses the modern metric system for sizing. Here's how they translate:
| Original Honda Size | Modern Heidenau Equivalent | Typical Position |
|---|
| 3.00-18 | 18" x 3.50" | Front (CB350/CB360) |
| 3.50-18 | 18" x 110/90 | Rear (CB350/CB360/CB450) |
| 3.00-19 / 3.25-19 | 19" x 90/90 | Front (CL350/CL360/CB450/CB550) |
These are the sizes we've verified fit without modification. Check the fitment chart on this page for your specific model.
About Heidenau
Heidenau has been building tires in Germany since the 1940s, specializing in motorcycle and scooter tires distributed worldwide. The Modern Street line brings their premium rubber compounds and engineering to vintage bikes that deserve better grip than what was available in the 1970's.
Installation
Difficulty: Intermediate
- Remove the wheel from the motorcycle. For the rear, remove the chain guard, cotter pin, and axle nut.
- Break the bead on the old tire using a bead breaker tool, then lever the tire off the rim with tire irons. Start prying 180 degrees from the valve stem — that's the hardest area.
- Install a new rim strip before mounting the new tire. Replace the rim strip with every tire change.
- Mount the new tire with the balance dots (double red dots) aligned with the tube's valve stem. Pay attention to the rotational direction arrow on the sidewall.
- Inflate the inner tube slightly before inserting it into the tire to give it shape and prevent pinching.
- Use baby powder inside the tire and on the tube to ease installation. Glass cleaner (like Windex) works as a lubricant between the tire and rim bead.
- Inflate the tire to approximately 25 psi before mounting the wheel on the bike — this lets you check for pinched tubes before everything is buttoned up.
- Reinstall the wheel and torque the axle nut to spec.
Remember: these are tubeless tires, but you MUST run tubes and rim strips on spoke wheels. It's perfectly fine — standard practice on vintage Hondas.

Frequently Asked Questions
Is the price for one tire or a pair?
One tire. Tires are sold individually — select your size above. Most customers order a front and rear tire together.
What size Modern Street tire fits my CB350 / CB360?
For the CB350 and CB360: 18" x 3.50" for the front, and 18" x 110/90 for the rear. The 110/90 rear is slightly wider than the original 18" x 3.50" but fits without modification and gives you a wider contact patch. Check the fitment chart for confirmed front/rear positions by model.
Do I need inner tubes with these tires?
Yes — if your bike has spoke wheels (most vintage Hondas do). These are tubeless tires by construction, but spoke wheels aren't airtight. You'll need inner tubes and fresh rim strips. It's perfectly fine and standard practice to run tubes inside tubeless tires.
What's the difference between Modern Street and Vintage Street?
Performance vs looks. The Modern Street has a contemporary tread pattern with a wider contact patch — it's the better tire for grip and handling. The Vintage Street has a period-correct block or ribbed tread that looks like what came on the bike from the factory. Both are German-made Heidenau tires with excellent rubber compounds. The Modern Street is "H" rated (130 mph) vs "S" rated (112 mph) for the Vintage lines.
