I was having some problem with drift and such, but I had checked the sidewalls of the tires to determine correct pressure and loaded them up to 110 pounds whcih was the max.
Big mistake. A mechanic at the Dealer told me very patiently to never use the number on the tire. Look at the tag by the drivers seat installed by Manufacturer. I did and it stiuplated only 82 pounds. 82 pounds! Huge difference. Rides much better than even when I bought it. They had put 90 pounds in the tires and that was wrong too.
When all else fails, read ths instructions...
