Powell Peralta SSF G-Slides Wheels Red 4pk | 59mm / 85a
A taller G-Slide with a firmer 85a feel.
The red 59mm G-Slide in 85a sits between the street-sized 56mm and the extra-soft 82a. It's for riders who want more roll and comfort than a hard wheel but a slightly firmer, quicker feel than the softest G-Slides.
Powell pours it in Soft Slide Formula, which is tuned for speed, slide control and life span. The 59mm diameter and 44mm width keep momentum up over rough bitumen, while the 85a urethane gives a slightly firmer feel than the 82a.
Key Features
- SSF urethane: made to roll fast, last long and slide

- 44mm width: stable for cruising and carving
- 85a hardness: a touch firmer than 82a

About Powell Peralta
Powell Peralta was founded in 1978 by engineer George Powell and skater Stacy Peralta in Santa Barbara, California. Powell had already been baking his own urethane wheels and building his own boards since the mid 1970s, and in 1979 the pair formed the Bones Brigade, the team that included Ray "Bones" Rodriguez, Steve Caballero, Tony Hawk, Lance Mountain, Rodney Mullen, Tommy Guerrero and Mike Vallely.
Today Powell Peralta still puts a big focus on urethane research and its own wheel formulas. Dragon Formula covers street and park, while Soft Slide Formula (SSF) covers cruising, freeride and downhill. Riders pick Powell because the wheels last, roll fast and slide when you want them to, and because the brand has been part of skating for close to five decades.
FAQs
What are 59mm 85a G-Slides best for?
Cruising, transition and mellow freeride on rough surfaces. They're bigger and faster than the 56mm version and firmer than the 82a, so they suit riders who want comfort without a mushy feel.
What does 85a mean?
85a is the hardness on the A scale. Lower numbers are softer and grippier, higher numbers are harder and slidier, and most street wheels sit around 99a to 101a. At 85a these G-Slides soak up cracks and rough bitumen, while the SSF urethane still lets them break into a slide.
Do I need risers for 59mm wheels?
On a popsicle deck with mid trucks, a 1/8" riser is a safe bet. On low trucks, go 1/8" to 1/4". High trucks and cruiser decks with wheel wells usually need nothing extra.
Do they come with bearings?
No. You get a set of 4 wheels with no bearings. Any standard 608 skateboard bearing fits, so you'll need a set of 8 (two per wheel), plus spacers if your bearings don't have them built in.
