My wife busted a sidewall on one of the Arachnid tires, after reading about these on another forum, we bought Federal Formoza from Amazon, I paid $91 for two tires. She told me that "everything is better", it handles better, corners better, smoother ride, no shimmies anymore, just simply awesome. She has a 2014 RTSNONE.
Unless you have some handling complaints.
The original Kenda tires were worse than almost anything else you could put on.
The jury is still out on the new tire design.
Keeping the front tires inflated to within .5 PSI of each others is good.
If you feel that it tends to wander all over the road, a laser alignment might help.
