The best 19-inch rear motorcycle tire depends on your bike’s required size and where you ride. The Tusk EMEX T-45 is best for intermediate-to-hard off-road terrain, while the Tusk EMEX T-35 set suits riders seeking matching soft-to-intermediate terrain tires. The WIG Racing tire is a size-specific option for certain electric dirt bikes; check your wheel and model before ordering.

Tusk EMEX T-45 100/90×19
Best for: Riders whose motorcycles call for a 100/90×19 rear tire and who mainly ride intermediate-to-hard terrain. This TUSK knobby is designed for hardpack, rocks, and rugged trails.
Its aggressive tread is intended to provide off-road grip, while reinforced, bridged side knobs are designed to reduce flex and support cornering stability. Those features make it a relevant choice for riders who want a dedicated dirt-oriented tire rather than a street-focused option.
Limitation: The listed terrain focus is intermediate to hard. Riders who spend most of their time on sand or very loose ground may prefer a tire specifically described for softer terrain. Confirm that 100/90×19 matches your motorcycle’s required tire size.
Tusk EMEX T-35 70/100×19
Best for: Off-road riders whose fitment calls for a 70/100×19 tire and who ride soft-to-intermediate terrain. TUSK describes this tire for sandy, loose, and packed dirt trails.
The deep, aggressive tread is designed to help with acceleration, cornering, and braking across varied trail surfaces. Its rubber compound is described as resistant to wear and abrasion in off-road use. Choose this option when the listed size and terrain match your bike and riding conditions.
Limitation: The product listing does not specify front or rear placement in its name or features. Verify the intended position and fitment with your motorcycle’s manual or a tire professional before buying.
WIG Racing 80/100-19 Rear Tire
Best for: Owners of compatible Sur Ron, Segway, or Talaria electric dirt bikes that use a 19-inch rear rim and require the listed 80/100-19 size. The product is presented for select electric dirt bike model years, but fitment should be checked for the specific bike.
The listing highlights a tough sidewall that allows lower pressure for off-road traction and fewer pinch flats. It also advises adding a rim lock because tire slip can pull the inner tube’s valve stem.
Limitation: It will not fit an 18-inch wheel, and the listing warns that its longer lugs and larger outer diameter may reduce low-end power on a stock bike. Check rim size and drivetrain considerations before choosing it.
Kenda K761 100/90-19
Best for: Riders looking for a 100/90-19 dual-purpose tire, provided the K761’s fitment is correct for their motorcycle. The listing identifies it as an off-road dual-sport tire and labels it for front or rear use.
Compared with the dedicated off-road Tusk knobbies, this Kenda is the more appropriate listing to investigate when a dual-purpose category is a priority. The provided product data includes the size and tire designation, but does not give detailed tread or road-performance specifications.
Limitation: The available features are limited, so they do not establish specific wet-weather performance or a particular balance of pavement and trail use. Check the motorcycle manufacturer’s tire requirements and confirm the tire’s intended position.
Tusk EMEX T-35 Front And Rear Set
Best for: Off-road riders replacing both tires who need a 90/100×21 front and 110/90×19 rear combination. The set is designed for soft-to-intermediate terrain, including loose dirt, sand, loam, and hard-packed trails.
The deep tread is intended to provide traction on varied off-road surfaces, and the rubber compound is described as resistant to wear and tear. Choose this set when both listed sizes match your bike and you want a coordinated front-and-rear replacement.
Limitation: The rear tire is 110/90×19, not 100/90×19. Do not assume it is interchangeable with another 19-inch tire; verify the complete size and required fitment first.
Buying Guide: How To Choose A 19-Inch Rear Tire
Which tire size should I buy?
Match the full size code in your motorcycle owner’s manual or on the existing tire. A 19-inch rim diameter alone does not establish fitment: the width and aspect ratio also matter. For example, 70/100×19, 80/100-19, 100/90-19, and 110/90×19 are different listed sizes. Confirm the required position, load requirements, and fitment with a tire professional when uncertain.
What terrain will you ride most?
For hardpack and rocky trails, the Tusk T-45 is specifically described for intermediate-to-hard terrain. For sand, loose dirt, and mixed packed trails, the Tusk T-35 listings emphasize soft-to-intermediate terrain. A knobby tread is an off-road-oriented choice; it should not be treated as a guarantee of street performance.
Do you need a rear tire or a complete set?
A rear-only tire can be practical when the front tire remains suitable and the replacement size matches. The Tusk T-35 set includes a 90/100×21 front and 110/90×19 rear. Check both sizes against your bike before selecting a set, especially if you are shopping for a 100/90-19 rear replacement.
Is the tire for an electric dirt bike?
Check the wheel diameter and the exact electric bike model. The WIG Racing listing cautions that it will not fit an 18-inch wheel and notes possible low-end power effects on a stock bike. It also recommends a rim lock to help prevent tire slip from pulling the tube’s valve stem.
Frequently Asked Questions
Does every 19-inch motorcycle tire fit every 19-inch wheel?
No. The full tire size and the motorcycle’s fitment requirements matter, not just the rim diameter.
What is the difference between the Tusk T-45 and T-35?
The T-45 is described for intermediate-to-hard terrain. The T-35 is described for soft-to-intermediate terrain, including loose dirt and sand.
Can I use a 110/90×19 tire instead of a 100/90×19?
Do not assume the sizes are interchangeable. Confirm the approved size for your motorcycle before changing tire dimensions.
Is the Kenda K761 listed as a rear tire?
The supplied listing calls it a dual-purpose front/rear tire in size 100/90-19. Verify that this size and position are approved for your motorcycle.
What should I check before ordering a tire for an electric dirt bike?
Confirm the bike model, rear rim diameter, and full tire size. Also review any listed notes about rim locks, tire slip, and possible changes in low-end power.
