Overview
The Motor Trend FlexTough Plus positions itself as the heavy-duty upgrade in Motor Trend's floor mat lineup, sitting above the popular FlexTough Contour in both price and capability. Where the Contour aims for everyday versatility, the Plus goes after drivers who need maximum protection -- think construction workers, off-road enthusiasts, and anyone who regularly subjects their vehicle interior to punishing conditions.
We tested the FlexTough Plus set for ten weeks across two vehicles: a 2021 Chevy Silverado 1500 that serves as a job site truck, and a 2023 Subaru Outback used for mountain biking and trail running. The conditions were deliberately harsh -- we wanted to see where the "heavy duty" label holds up and where it falls short.
Motor Trend has clearly learned from the Contour's success and applied those lessons to a burlier product. The FlexTough Plus uses thicker rubber, taller sidewalls, and a more aggressive tread pattern designed to channel water and debris away from your vehicle's carpet. The question is whether these upgrades justify the price premium over the already-excellent Contour.
Pros & Cons
What We Like
- Heavy-duty rubber construction resists cracking and curling
- Deep grooves channel water and slush away from shoes
- Anti-slip backing grips carpet without shifting
- Trim lines make universal fitting straightforward
- Very affordable for a 3-piece set
Watch Out For
- Universal fit means gaps around pedals on some vehicles
- Rubber smell lingers for about a week
- Not as thick as the Contour model
How We Tested This
Each mat undergoes 8 weeks of daily use testing, including water pour tests, mud tracking, UV exposure, and anti-slip verification. This mat was tested over a 8 weeks period before we published our findings.

Design Differences from Contour
Side by side with the FlexTough Contour, the Plus immediately looks like the bigger, meaner sibling. The rubber is noticeably thicker -- roughly 20% more material by weight -- and the raised edges climb higher, providing an extra half inch of containment around the perimeter. The tread pattern shifts from the Contour's geometric design to a more aggressive channel-and-ridge layout that directs water toward drain points.
The underside anti-slip system also gets an upgrade. Where the Contour uses simple nibs, the Plus features a full grid of interlocking teeth that bite into factory carpet with serious authority. During our testing, we never once experienced mat movement, even during aggressive off-road driving in the Outback where the footwell was taking lateral forces.
The trim-to-fit system carries over from the Contour, with the same molded guidelines making customization straightforward. Motor Trend wisely kept what works while beefing up the protection elements. The color options are limited to black and gray, which is fine for a product targeting the utility-first buyer.
Material Quality
The FlexTough Plus rubber compound feels denser and more rigid than the Contour's material while still maintaining the flexibility needed to conform to footwell shapes. We performed bend tests at various temperatures and found the Plus remains pliable down to about 10 degrees Fahrenheit -- slightly stiffer than the Contour in extreme cold, but still functional.
In terms of chemical resistance, we exposed the Plus to motor oil, brake cleaner, and road salt brine. The motor oil wiped away cleanly with no staining after 24 hours. Brake cleaner left no visible damage or discoloration. Road salt, which can be devastating to cheaper rubber mats, dissolved cleanly with a water rinse.
The material odor, which plagues many rubber floor mats, was present out of the box but dissipated within about 48 hours. This is faster than most competitors in the heavy-duty category, and significantly better than some budget mats we have tested that retained a chemical smell for weeks.
Coverage Test
In the Silverado, the Plus mats covered an impressive amount of footwell real estate. The truck's generous footwells gave the oversized mats room to work, and after minimal trimming we achieved approximately 90% floor coverage. The tall sidewalls integrated well with the Silverado's raised door sills, creating a nearly seamless containment zone.
The Outback presented more of a challenge due to its contoured footwell design. We needed to do more precise trimming around the center console area and near the pedals, but the end result was still strong coverage. The Plus's taller edges proved their worth here, as the Outback's footwell has some complex angles that shorter-walled mats struggle to protect.
One notable improvement over the Contour is the Plus's rear mat design. The rear piece provides better center hump coverage and wider side coverage, which matters in vehicles where rear passengers tend to shift their feet around. The overall protection envelope of the Plus set is measurably larger than the Contour, which justifies the price bump for buyers prioritizing maximum coverage.
Winter Performance
Winter testing is where the FlexTough Plus truly separated itself from the Contour. During a particularly brutal February in Minnesota, we tracked slush, road salt, and packed snow into both test vehicles daily for three weeks. The Plus's taller sidewalls contained the meltwater without issue -- we never saw overflow, even when both front mats had standing water from melting snow boots.
The channel tread pattern proved its worth in winter conditions. Water naturally flowed into the channels and pooled in low spots rather than spreading across the entire mat surface, keeping the driver's heel area relatively dry. This is a meaningful quality-of-life improvement during commutes when you do not want your feet sitting in a puddle.
Cold weather rigidity was our one concern going in, but the Plus remained flexible enough to handle and install even at sub-zero temperatures. We removed and cleaned the mats twice during the winter testing period, and the rubber did not crack, split, or show any signs of cold-weather degradation. For northern climate drivers, the FlexTough Plus earns a strong recommendation.
Who Should Buy This
The FlexTough Plus is purpose-built for drivers who put their vehicles through heavy use. If you work in construction, landscaping, farming, or any trade that means climbing into your truck with dirty boots, these mats will pay for themselves in carpet protection within weeks. The heavy-duty rubber and tall containment walls handle industrial-level abuse without complaint.
Outdoor enthusiasts will also appreciate the Plus's capabilities. Mountain bikers, hikers, skiers, and hunters who regularly load wet, muddy gear into their vehicles need this level of protection. The Plus catches everything the Contour would, plus the extra containment handles the overflow situations that active lifestyles create.
If you are primarily a commuter with occasional weekend errands, the FlexTough Contour is probably sufficient and will save you money. The Plus earns its premium through superior containment and durability under heavy-duty conditions. Match the mat to your lifestyle, and either product will serve you well.
Our Verdict
The FlexTough Plus is a solid budget workhorse that handles rain, snow, and daily grime without complaint. It lacks the refinement of custom-fit mats, but at $35 you're getting reliable all-weather protection.
