WHAT OWNERS SAY

❝
Our initial impressions on road noise and traction have been positive, and they do look great on the XPED BC Sequoia.

❝
After wheeling the rocks, sand, mud, snow, and everything in between on both tires, we definitely have experienced what off-roading on the STT Pros is all about, and man, this is one seriously impressive off-road tire. This tire has absolutely dominated dry surfaces with its sticky rubber compound, more so than the EVO M/T.

If you are a daily driver who commutes or someone who sees snow/ice on the road often, I would opt for the Evolution M/T. If you are more focused on general off-road performance over road-noise, and snow/ice performance, then definitely look at the STT Pros.

Having great off-road performance while maintaining long tread life is where I see the STT Pro really standing out amongst the crowd.

The Discoverer STT Pro’s dry performance is not outstanding but enough for me to use for a long time. Even I believe that the product is suitable for everyday use. Not many all-terrain tires achieve the same performance.

We can say first hand that the tire noise has noticeably been reduced from the original STT design.

The first thing that hits you about the STT Pro’s is that they are QUIET compared to the MT/R’s. At a steady 50 mph (on the same stretch of road), I recorded a 10 decibel difference between the STT Pro’s and the MT/Rs. That’s pretty huge.

›What the forums are saying
“They are surprisingly quiet for such an aggressive tire. These are the quietest M/T on the market.”
— 4Runner Forum
“I love these tires. I've got about 2k on mine and they still have the nubs on the tread.”
— Tacoma World
“Trail riding they can't be beat. The closest to a draw back is when they sit for a while.”
