I'm giving this tire four stars because once the tire is mounted on your bike, it performs well.
However, I had a lot of trouble mounting the tires on my rims. What used to be a ten minute task in tube-land ended up taking me most of the day. Granted, this was my first experience with tubeless tires so it's not the tire's fault I was on a steep learning curve.
I ended up inadvertently ruining one tire by inflating it to the max and then having it explode spraying me and my bike with sealant. Again, mea culpa. I thought taking it up to the max air pressure would ensure the bead would seal. Unfortunately, the bead didn't hold for more than 15 minutes and after it popped, I was unable to re-mount the tire as it seemed like wire inside the tire had been stretched or otherwise damaged. Again, not the tires fault!
I ended up purchasing a Schwalbe tire as a replacement for the damaged one since I couldn't find another G-One Speed in stock at my LBSs. I hope this is useful to someone with a big caveat to not inflate your new tire to its max!
Have used these tires for a bit over two years now, and find them satisfactory for most conditions. I run them at close to 80psi most of the time, and down to 60psi on rough trails. Not a pure mountain bike tire by any means, but can take on most gravel, dry dirt, grass and small rocks with ease. Gets a bit squirrelly in wet conditions and larger rock. Runs very smoothly on dry roads. I am very confident on these tires as the tread and construction appear very solid and puncture resistant. Only reason I would change tires would be to go more aggressive for off-road wet and large rock conditions.
After, 3,700 miles on the Great Divide, i would recommend the Allaround over the Bite for better durability and less likely to flat in thorn country, i.e., New Mexico.
