Cooper Discoverer STT Pro
Cooper STT Pro is a value-leaning MT with strong rock/mud performance and severe-snow rating.
Cooper's STT Pro splits the difference between AT and MT — labeled an MT and aggressive enough to handle rocks and mud, but mannerly on highway and severe-snow rated (a rare combo for MTs). Common sizes: 33x12.50R15, 35x12.50R15. Cost is typically a touch below comparable Toyo/Nitto MTs.
Commonly recommended for overland XJs that occasionally see real off-road and need snow capability. Wear and noise are average for the MT category.
Why it works
- severe-snow rated MT
- good value
- strong rock/mud
Trade-offs
- available sizes thinning
- not the toughest sidewall
