OULEME Curved Leveling Blocks (2-Pack) for RV Tire Changes — Lift up to 6" with Chocks and Rubber Mat

If you’ve ever tried to change a tandem-axle trailer tire on uneven ground, you already know the problem: the jack helps, but it doesn’t always stop the tire area from rolling or slipping. OULEME’s curved leveling blocks are designed specifically for raised tire changes, giving you a controlled setup (and pairing) with included chocks and non-slip rubber matting.

On paper, this is the kind of tool that’s meant to live in your RV/camper storage and do its job without drama. The key claim is the lift height—up to 6"—which fits the “quick practical tire-change” use case rather than anything heavy-duty for extreme off-roading or specialized setups.

The essentials (what these are for)

These are curved leveling blocks used as a raised ramp/aid for changing tires on a tandem axle trailer. The curved shape helps create a more stable ramp-like surface so you can position the wheel area more deliberately, not just rely on a jack point and hope the rest behaves.

The set comes as a 2-pack and includes a chock and a rubber non-slip mat. That matters because tire changes are when small slips feel big—especially when your goal is to reduce movement while you swap the tire.

What you’ll notice in use

The design focuses on grip and coordination between the leveling block and the chock. The leveler and the chock use a precise gear mesh design intended to prevent slippage between them. Add thickened rubber non-slip pads, and the idea is that the base stays put while you work.

There’s a real-world difference between a flat block and something that’s shaped to guide the tire area into position. For example: if you arrive with the trailer on mildly uneven ground, you can place the block where the tire needs to land, seat the chock system, and use the ramp-like lift to get the tire up for removal. It’s not complicated, but it’s the kind of setup that can make you feel more in control.

Key features that actually matter

• 6" lift height: intended for raising the tire-change area up to 6".
• Curved leveling/ramp design: supports a raised tire-change workflow rather than just being a simple support block.
• Anti-slip approach: includes thickened rubber non-slip pads, plus a gear mesh interaction between the leveler and the chock.
• Durability focus: made from premium polymers with added anti-aging and UV-resistant materials, including anti-UV additives intended to slow aging.

One limitation to keep in mind: lift height and stability are only as good as your surface. If you’re on very soft ground, loose sand, or anything unpredictable, no block-based system can fully replace proper safety judgment.

Capacity and limits (so you don’t buy the wrong tool)

OULEME states these blocks are for trailers up to 35,000 lbs in weight, with tire sizes up to 32". That gives you a reasonable “range” to check before buying.

This is also a product aimed at common RV/camper tire-change situations (especially tandem axle aid changing). It’s not described as something for specialized industrial lifting, extreme recovery scenarios, or anything that replaces professional guidance for unsafe conditions.

Materials and longevity: the UV/aging angle

A lot of RV accessories fade into storage and then get reused months later. The polymer material and the mention of UV resistance/anti-aging additives are relevant if your trailer sits in sun for long periods.

That said, these tools are still tools you should inspect before use—look for wear, deformities, or anything that could compromise grip. Anti-UV additives can slow aging, but they can’t stop wear from use and contact with the road or debris.

What to check before you commit

Before you add these to your travel kit, double-check: - Your tire size (the listing specifies up to 32"). - Your trailer’s relevant weight range (the listing specifies up to 35,000 lbs). - Whether your setup matches a tandem axle aid changing workflow—the product is positioned around that specific use. - Ground conditions where you’ll place the blocks. Even with anti-slip design, stability depends heavily on what’s under the system.

If you’re shopping because you want the simplest “keep it in the compartment and use it when needed” solution, this aligns with that. If you’re expecting a one-tool answer for all terrain types and heavy recovery, you may find it a bit narrow for that broader job.

What’s included

The package is described as a 2-pack and includes a chock and a rubber mat.

Buying verdict

It makes sense to buy these OULEME curved leveling blocks if you regularly haul an RV/camper trailer with tandem axles and you want a dedicated raised aid system for changing tires—especially if you value the anti-slip idea (rubber pads plus the gear mesh interaction between the leveler and chock).

You may want to skip them if your tire size is outside the stated range, if your trailer’s use doesn’t match tandem axle tire-change needs, or if your typical ground conditions are so irregular that even a 6" lift tool can’t give you the stability you expect.

Mini FAQ

Are these blocks only for tandem axle trailers?

The product is described for tandem axle trailer tire changes, so it’s safest to assume the design and intent are tuned for that setup.

How much lift do they provide?

The listing describes a lift height up to 6" for the tire-change workflow.

What grip features are included?

You get a gear mesh design between the leveler and chock intended to reduce slippage, plus thickened rubber non-slip pads and a rubber mat.

What trailer weight and tire size are they meant for?

They’re stated for trailers up to 35,000 lbs and tire sizes up to 32".

Are they UV resistant?

They’re described as using anti-aging and UV-resistant polymers with anti-UV additives intended to slow aging.
