›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.”
— FJ Cruiser Forums

WHAT OWNERS SAY
❝
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.
❝
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.
❝
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.
