Imagine cruising down an empty highway when a sudden afternoon storm turns the pavement slick. You need a rear 170 80r15 motorcycle tire that holds the line without hesitation. I have waded through mountains of rider data to compare these nine replacements. My personal view is that rubber choice makes or breaks your ride. Let me walk you through an honest, ranked comparison of your top options.

1. Dunlop D404 Rear Motorcycle Tire 170/80-15 (77H) Black Wall

Dunlop D404 Rear Motorcycle Tire 170/80-15 (77H) Black Wall

This model earned its place on my list through pure factory pedigree. Dunlop built this rear tire to mirror original equipment standards for classic cruisers.

I think the tread compound strikes a dependable balance for casual weekend riders. You get predictable dry traction, though wet grip can feel slightly loose once the rubber ages.

Buyers frequently mention that this tire matches factory handling characteristics well.
Riders appreciate the straightforward black wall aesthetic for vintage builds.
Some notes suggest tread life diminishes a bit faster on heavy highway tours.

Heavy cruiser owners carrying extra luggage will find their match here. Shinko engineered this heavy-duty casing specifically to bear substantial machine weight on long tours.

I appreciate how the reinforced carcass handles fully loaded saddlebags without squirming. Keep in mind that softer rubber compounds trade away longevity for initial grip.

3. Kenda Kruz K673F 170/80-15 77H Rear Motorcycle Tire – Bias Ply, Tubeless, DOT Approved, High-Mileage Cruiser Tire with Excellent Wet Grip and Stability, (170-80-15 77H) Includes Kenda Keychain

Kenda Kruz K673F 170/80-15 77H Rear Motorcycle Tire - Bias Ply, Tubeless, DOT Approved, High-Mileage Cruiser Tire with Excellent Wet Grip and Stability, (170-80-15 77H) Includes Kenda Keychain

An unexpected included keychain adds a curious touch to a serious high-mileage utility tire. Kenda packed this bias-ply design with deep grooves meant to channel standing water away from the contact patch.

I find the wet-weather siping quite impressive for the price point. The stiffer sidewall does transmit more bumps from cracked asphalt into the chassis.

Commuters praise the reliable traction during unexpected rainstorms.
Feedback consistently points out high overall mileage before replacement.
Some users report a slightly stiffer ride quality over rough expansion joints.

MICHELIN Commander II Cruiser Bias Tire-170/80B-15 77H

Critics often point out the higher upfront cost associated with this premium French brand. Yet, I rank it as my number one overall pick because the engineering justifies every penny.

You get an aramid fiber belt that resists centrifugal growth and delivers exceptional mileage. My judgment is that you will save money over time by skipping frequent tire swaps.

Owners consistently report double the mileage compared to stock tires.
Riders note crisp cornering response even when the tread nears the wear bars.

5. Kenda Cruiser K671 Motorcycle Street Tire – 170/80H-15

Kenda Cruiser K671 Motorcycle Street Tire - 170/80H-15

Stepping down from my top pick, this K671 variant shifts focus toward sporty agility rather than pure touring mileage. Kenda designed this street tread for riders who prefer a more responsive lean angle in corners.

I think the tread profile feels noticeably quicker to turn than standard cruiser blocks. Just remember that sport-oriented rubber on a heavy cruiser can wear through the center rather fast.

City riders mention that nimble handling improves low-speed maneuverability.
Feedback indicates good grip during aggressive braking maneuvers.
Rear wear can accelerate quickly if you spend most of your time on straight interstates.

Dunlop D404 Rear Motorcycle Tire 170/80-15 (77H) Black Wall for Triumph America 865 2009-2016

A strong reputation among British cruiser enthusiasts propelled this specific version onto my radar. Dunlop tailored this D404 iteration to match the precise weight distribution of mid-size Triumph cruisers.

I believe the predictable tracking makes it a safe default choice for owners of those specific machines. On the downside, technology has marched past this older design in terms of wet-weather braking.

Triumph owners value the exact factory fitment for their rear wheels.
Riders cite smooth rolling behavior on freshly paved two-lane roads.

Factory cruiser setups earned this tire its secure mid-tier ranking. Bridgestone tuned the Excedra line specifically for heavy Japanese touring motorcycles rolling off assembly lines.

I like the stable highway manners this rubber displays during crosswinds. Do not expect extraordinary tread life if you twist the throttle hard away from traffic lights.

Owners of metric cruisers frequently replace factory rubber with this exact model.
Highway feedback highlights a quiet, low-vibration roll at speed.
Aggressive riders notice faster wear on the central contact patch.

8. Kenda K673 Kruz Rear Tire (170/80-15)

Kenda K673 Kruz Rear Tire (170/80-15)

Budget-conscious highway cruisers represent the primary audience for this standard Kruz model. Kenda focused on delivering basic, DOT-approved dependability without inflating the price tag.

I consider this option a solid wallet-friendly fallback for daily commuters. The rubber compound tends to harden slightly faster than premium alternatives as the seasons change.

Budget-minded buyers praise the low entry cost for standard touring sizes.
Reviewers note adequate dry grip for everyday errand running.
Some long-distance riders wish for softer traction during cold morning commutes.

An interesting asymmetrical groove pattern catches the eye before you even mount this commuter tire. Kenda built this specific SKU to handle the daily stop-and-go grind of urban street riding.

I think the sidewall construction handles potholes and rail crossings with decent composure. You will likely sacrifice some total seasonal mileage compared to dedicated heavy touring rubber.

City riders point out reliable stopping traction on greasy urban asphalt.
Feedback suggests the tire warms up quickly during short trips.
Tread depth diminishes faster under heavily loaded two-up riding conditions.

Choosing Between Them

For your garage, I recommend choosing the Michelin Commander II as your primary cruiser upgrade because it delivers exceptional tread life and sharp handling. If your budget is tighter, turn toward the Kenda Kruz for reliable everyday mileage without spending a fortune.

Keep in mind that cruiser bias tires generally demand careful pressure checks every weekend to prevent premature center wear. Consistent inflation remains the single best tool you possess to protect your rubber investment.
