Can You Fit 20-Inch MRR HR3s on an Acura RL? (Yes — and Bigger Too)

Can You Fit 20-Inch MRR HR3s on an Acura RL?

Yes — and people have run 22s too. The argument about whether 20″ is “safe” on the RL keeps focusing on the wrong number. Diameter matters, but offset is what actually determines whether a wheel clears or rubs.

What the MRR HR3 Is

The HR3 is a 10-spoke, one-piece alloy wheel from MRR with a concave face and exposed lugs. It comes in 19″, 20″, 21″, and 22″ diameters, with widths from 8.5″ to 11″ and offsets ranging from +25 to +45. Available finishes include Silver Machined Face and Chrome. Multiple bolt patterns are offered, which is part of why the HR3 shows up on a wide range of platforms — from sport sedans to larger luxury cars like the RL.

How 20″ HR3s Fit the Acura RL

There are real builds to reference. A 2009 Acura RL has been documented running 20×9.5 MRR HR3 wheels with 225/35 tires on BC Racing coilovers — clean fitment, no major cuts or body modifications. The RL’s fender clearance handles the diameter jump from the OEM 17″ or 18″ setup better than most people expect.

Offset is the number that needs actual attention. Run too low an offset on a wide wheel and the lip pushes toward the fender; run too high and it tucks, which changes stance but can stress the wheel bearings over time. For the RL at 20×9.5, the +25 to +35 range is the territory most builds land in — though whether you’re on stock suspension or lowered changes the picture.

What It Takes to Run 22s

It’s been done. A 2006 Acura RL has been fitted with 22″ MRR HR3 Chrome wheels. Going from 20″ to 22″ is where most people need to think more carefully about ride height. The RL doesn’t have extreme factory camber, which helps — it tolerates bigger wheels without the rubbing geometry some sport-tuned sedans fight.

“Required work” in these fitment discussions usually means coilovers or lowering springs so the fender sits closer to the wheel, plus careful offset selection. It rarely means cutting the inner liner. A coilover setup gives you the adjustability to find the sweet spot after the wheels are mounted.

Tire Width and Sidewall

Going up in diameter without also going very wide in the tire can actually help clearance at full steering lock. The 225/35 combination on a 20×9.5 is a documented starting point for the RL. Push to a 245 or 255 and you’ll want to test clearance carefully on full lock, especially on a lowered car.

Fitment galleries are more useful than spec charts here. Photos of the exact wheel-tire-vehicle combination, with suspension notes, tell you things a calculator can’t.
