Straight answers on the Toyo Tires Open Country R/T Pro 2.2: what the 4.9-inch size means, how to pick a compound, and how to mount these tires without guesswork.
Quick answer
The Toyo Tires Open Country R/T Pro 2.2 is a 4.9-inch 2.2 crawler tire sold in pairs, and the compound choice matters more than the size: pick Super Soft RED for lighter rigs and Soft WHITE for heavier rigs or muddy, higher-speed running. Mount them on 2.2 beadlock wheels and check clearance before you glue or clamp anything.
What the 4.9-inch figure actually tells you
The 4.9-inch number is the tire's overall diameter, not its mounting width. It tells you how much ground clearance and approach angle you gain compared with a smaller 2.2 tire, but it says nothing about which wheel width or foam it needs. Treat it as a clearance figure first and a looks figure second.
Because the catalog lists only the diameter and the 2.2 class, not a recommended wheel width or foam size, you have to confirm fitment against your specific wheel and body. That missing data is a real limitation, not something to assume.
Why the compound choice changes the whole setup
The two compounds are not a quality ladder; they are a weight-and-terrain decision. Super Soft RED is the stickiest and softest option, which helps on dry, wet, slick, and high-traction rock but lets lugs deflect more under load. Soft WHITE gives more lug support for heavier rigs and holds up better in mud or at higher speed.
If you run a light rig on technical rock, RED is the obvious pick. If your crawler is heavy or you split time between mud and speed, WHITE keeps the tire from folding over. Choosing the wrong one is the most common reason a good tire feels disappointing.
Mounting 2.2 tires: where most fitment problems start
Most mounting issues come from seating the bead unevenly or trapping the foam, not from the tire itself. Work the bead onto the wheel by hand first, confirm the foam sits centered, then tighten or glue in stages. A tire that looks seated can still be pinched on one side.
If you are reusing wheels, inspect the beadlock ring and screw threads before mounting. A stripped ring will not hold a soft compound under load, and that failure looks like a tire problem when it is a hardware problem.
Toyo R/T Pro 2.2 fitment questions answered
- Will these fit my 2.2 crawler wheels?
- They are a 2.2-class tire, so they are intended for 2.2 wheels. The catalog does not list a recommended wheel width, so test-fit on your actual wheel and confirm the bead seats fully before gluing or clamping. If the bead will not seat by hand, stop and check wheel width before forcing it.
- Should I choose RED or WHITE compound?
- Choose Super Soft RED for lighter rigs and dry, wet, slick, or high-traction rock. Choose Soft WHITE for heavier rigs, muddy conditions, or higher-speed applications where you need more lug support. Match compound to rig weight first, terrain second.
- How do I mount them without pinching the foam?
- Seat the bead by hand, center the foam, then tighten or glue gradually and check the bead line all the way around before final torque. Do not rely on the tire pulling itself straight. Inspect the bead line after the first stage of tightening, not at the end.
- Do I need to check body clearance with a 4.9-inch tire?
- Yes. A 4.9-inch diameter is larger than many stock 2.2 tires, so cycle the suspension and check for rubbing at full steering lock and full compression before your first run. Test clearance with the body mounted, not on a bare chassis.
