The best 18-inch rear dirt bike tire depends on your bike’s required size and the terrain you ride. The Tusk EMEX T-45 110/100-18 is best for intermediate-to-hard trails, while the WIG Racing 110/100-18 is aimed at loose dirt and mud. The PaoWin suits riders seeking a 110/100-18 tire with listed dimensions, and the Kenda K760 and IRC GP-1 offer options for riders who also use pavement. Check your owner’s manual before choosing: an 18-inch rim alone does not confirm tire fit.
| Tire | Listed size | Best suited for |
|---|---|---|
| Tusk EMEX T-45 | 110/100-18 | Intermediate-to-hard terrain |
| WIG Racing Dirt Hoe | 110/100-18 | Loose dirt, sand, and mud |
| PaoWin P-2006 | 110/100-18 | Buyers comparing size and construction details |
| Kenda K760 | 100/100-18 | Mostly off-road riding with some road use |
| IRC GP-1 | 4.10-18 | Dual-sport use on pavement and dirt |
Tusk EMEX T-45 110/100-18
Best for: Riders using hard-packed trails, motocross tracks, or rugged intermediate-to-hard terrain. This rear tire has an aggressive tread pattern, and its bridged side knobs are designed to reduce flex and resist chunking during turns.
It is a useful choice when cornering control on firmer ground matters. The listed size is 110/100-18, so compare it with the tire size specified for your motorcycle rather than relying only on the rim diameter.
Limitation: The provided features focus on intermediate-to-hard terrain, so riders prioritizing very loose or muddy conditions may prefer a tire specifically described for those surfaces.
WIG Racing Dirt Hoe 110/100-18
Best for: Off-road riders who regularly encounter loose dirt, sand, or mud. WIG Racing describes this as a mid-hard rear tire with widely spaced tread intended to help maintain traction without clogging in loose conditions.
The product listing also highlights a stiffer sidewall intended to help prevent pinch flats during aggressive riding. Choose this tire if your terrain mix includes soft surfaces and you want a 110/100-18 option.
Limitation: The listing does not provide a specific road-use rating or application, so verify suitability for your motorcycle and intended use before buying.
PaoWin P-2006 110/100-18
Best for: Buyers who want a 110/100-18 tire with several listed specifications to compare. The product details state a 4-ply construction, 16 mm tread depth, 127 mm section width, and a 64M load and speed designation.
The listing describes the tire for 18-inch rims and says it can be used as a front or rear tire on compatible motorcycles. Its stated maximum load and pressure are product specifications, not a substitute for the limits in your motorcycle manual.
Limitation: The listing’s broad compatibility language does not establish fitment for every bike. Confirm the size, position, and required load and speed ratings for your model.
Kenda K760 100/100-18
Best for: Riders whose approved fitment is 100/100-18 and who want a tire designed primarily for dirt with some road use. Kenda lists tall, aggressive knobs for varied terrain, a durable compound, and a 90% dirt/10% road application.
Compared with the 110/100-18 choices here, this is a different size. It may suit a bike that calls for 100/100-18, but it should not be treated as a direct replacement for a wider tire without checking manufacturer guidance.
Limitation: Its stated use is heavily weighted toward dirt, so it is not the best match for riders seeking a tire primarily for pavement.
IRC GP-1 4.10-18 Dual Sport
Best for: Dual-sport riders who need a rear tire for both pavement and off-road surfaces and whose bike specifies 4.10-18. The IRC GP-1 uses knobs for loose-surface traction, braking, and cornering, while its listing says the tread wears less quickly on the street than a full knobby.
This is a better road-and-trail compromise than a tire described exclusively for aggressive off-road use. The listed size uses inch-based sizing, so do not assume it is interchangeable with a metric 18-inch tire.
Limitation: The product information advises verifying tire and vehicle data with a tire professional, the vehicle placard, or the owner’s manual.
Buying Guide: How to Choose an 18-Inch Rear Tire
Which tire size should I buy?
Start with the size printed on your current tire and the fitment specified in your motorcycle owner’s manual. The products here include 110/100-18, 100/100-18, and 4.10-18. These are not automatically interchangeable just because each is associated with an 18-inch rim. Width, profile, clearance, load rating, and the bike’s approved fitment also matter.
What terrain do you ride most?
- Hard-packed trails and tracks: Consider the Tusk EMEX T-45, whose features focus on intermediate-to-hard terrain and reinforced side knobs.
- Loose dirt, sand, or mud: The WIG Racing tire is specifically described with spaced tread intended to resist clogging in loose conditions.
- Mixed road and trail use: Compare the IRC GP-1 or Kenda K760, while accounting for their different sizes and stated road-use emphasis.
Should you choose a road-oriented or off-road tire?
A tire designed mainly for dirt may provide a more suitable tread pattern for off-road riding, while a dual-sport design aims to balance pavement and loose-surface use. Match the tire to your actual riding conditions and local road requirements. Do not infer road legality from the word “dual sport” alone; check the product and vehicle documentation.
What specifications should you verify?
Confirm the tire’s position, size, load and speed markings, and any tube or rim requirements with the manufacturer or a qualified tire professional. The PaoWin listing provides specific load and pressure figures, but those details do not override the motorcycle’s limits. Also check physical clearance before changing tire dimensions.
Frequently Asked Questions
Does any 18-inch tire fit an 18-inch rear wheel?
No. The rim diameter is only one part of fitment. Tire width, profile, approved size, and motorcycle clearance must also match.
Are 110/100-18 and 100/100-18 the same size?
No. They have different listed widths and profiles. Use the size approved for your motorcycle unless a tire professional or manufacturer confirms an alternative.
Which option is described for mud and loose dirt?
The WIG Racing 110/100-18 listing highlights spaced tread intended to work in mud, loose dirt, and sand without clogging.
Which listed tires include pavement use?
The IRC GP-1 is described for on- and off-pavement handling. The Kenda K760 is listed as a 90% dirt/10% road tire. Confirm fitment and road-use requirements for your bike.
