What 19×7-8 Means and How to Check Fit
The size 19×7-8 means roughly 19 inches tall, 7 inches wide, for an 8-inch rim. Use this checklist before buying:
- Rim size: your wheel must be 8 inches. If your wheel is 10 inches, see our 10-inch rim ATV tires instead.
- Existing tire size: read the size on your old tire sidewall. Mini bikes such as the Coleman CT200U and Baja Warrior are named in listings for this size, but confirm in your manual.
- Front and rear: many mini bikes use one size on both wheels, but check yours before ordering a pair.
- Quantity: some listings are a set of 2 and some are a single tire.
- Tread: knobby tread suits dirt and grass. A directional tire has an arrow that must point the way the wheel turns forward.
Also see small ATV and go-kart tires if the same wheels go on a kart.
MOTOOS Non-Directional 19×7-8 Set: Casual Trail Pick
This set of 2 has a non-directional tread, which means there is no rotation arrow to get wrong when mounting. The listing data shows 4-ply construction and a 176 lb load capacity. The link slug on Amazon mentions Roadstar rather than MOTOOS, so confirm the brand and quantity on the page.
What buyers mention
Amazon buyers commonly mention that the tires fit as expected and mount without too much trouble. Some say you may need to lower the pressure in soft sand.
- Good for: backyard riding, light trail use, replacing worn stock tires.
- Limits: not an aggressive mud tire, and 4-ply is lighter duty than 6-ply.
SunF A051 6-Ply 19×7-8 Tires: Heavy-Use Pick
Choose this set if you ride often or want a tougher tire than the stock ones. Listings show a 6-ply tubeless tire with a 16 mm tread depth, a 220 lb load figure and a knobby off-road pattern. The listing text and spec table disagree on whether the tread is directional, so look at the sidewall for an arrow before you mount.
What buyers mention
Amazon buyers commonly mention a strong tread and good wear on mixed terrain, and a firmer ride than thin stock tires. Some say mounting takes patience.
- Good for: regular trail riding, grass and dirt, replacing weak stock tires.
- Limits: stiffer sidewalls are harder to mount, and the heavier build may feel less lively.
EOPOAYI 19×7-8 Knobby Tire: Coleman and Baja Style Replacement
This knobby tire is advertised as a replacement for 110-125cc mini bikes. Retailer pages for it name the Coleman CT200U and BT200X, Baja Warrior and similar bikes, but verify your exact model in the Amazon fitment list. The listing appears to be for a single tire, so order two if you need a pair.
What buyers mention
Amazon buyers commonly mention a good fit, a thick tread and easy enough mounting with basic tools.
- Good for: replacing one worn tire on a Coleman or Baja style bike.
- Limits: sold singly, so you may need two orders for a matched pair.
MOTOOS 6PR Heavy-Duty Directional Set
The listing title describes an all-terrain, heavy-duty 6PR directional set of 2, so treat it as an off-road tire rather than a street tire. Pick it if you want a sturdier build and are happy to mount the tires in the correct rotation direction. A 220 lb load figure and a 24 lb weight are shown in the listing data.
What buyers mention
Amazon buyer comments are mixed here. Some like the ride and look, while others report air-retention or quality problems out of the box, so inspect each tire and bead when it arrives.
- Good for: riders who want a heavy-duty directional tread.
- Limits: some buyers report sealing issues, and it must be mounted in the right direction.

How to Mount 19×7-8 Tires
- Remove the wheel and let the old tire fully deflate.
- Break the bead and remove the old tire, then clean rust and dirt from the rim.
- Check the rotation arrow on directional tires and match it to forward travel.
- Coat both beads with soapy water and work the new tire onto the rim.
- Inflate slowly to seat the beads, then set the pressure printed on the sidewall. ATV-size tires run low pressure, so do not overinflate.
- Check for slow leaks with soapy water, then refit the wheel and tighten the axle nuts.

19×7-8 Mini Bike Tires FAQ
What does 19×7-8 mean on a mini bike tire?
It means the tire is about 19 inches tall and 7 inches wide and fits an 8-inch rim. Tires in this size are used on many mini bikes, go-karts and small ATVs.
Which mini bikes use 19×7-8 tires?
Listings for these tires name bikes such as the Coleman CT200U and BT200X and the Baja Warrior. Always compare the size printed on your current tire and check your manual before ordering.
Should I choose a directional or non-directional tread?
A non-directional tire can be mounted either way. A directional tire has an arrow and must be mounted so the arrow points in the forward rolling direction. Either can work, so choose by tread style and ply.
Are tubeless 19×7-8 tires worth it?
Tubeless tires remove the tube as a leak point once the bead seals, and they need a clean rim. If your rim is rusty or rough, clean it first or run a tube instead.
What pressure should I run in 19×7-8 tires?
Use the pressure printed on the tire sidewall, because ATV-size tires run low pressure and the maximum varies by model. Do not overinflate to seat a bead beyond the stated limit.
Does ply rating matter for a mini bike?
A higher ply rating, such as 6-ply versus 4-ply, usually means a stiffer and tougher carcass for harder use. It can also make the tire heavier and harder to mount.
Bottom Line
Match the 8-inch rim and the quantity first, then pick by use. SunF A051 for hard use, the non-directional set for casual riding, EOPOAYI for a single Coleman or Baja style replacement, and the 6PR MOTOOS if you want a heavy-duty directional tread.
