It looks like only few sellers on eBay are selling Solus KH23, almost nobody else, Discount Tire Direct or Tirerack or Tread Depot, has it, except Tire-Easy.com. What is unusual is everyone has only one size 245/45-19.
It has asymmetrical tread design with UTQG of 480 A A and W speed rate. The price seems very reasonable of $90/ea for 245/45-19 + shipping at Tire-Easy.com and little more on eBay. For 16-17" size, I expect the price to be in the $70.
TedSexington, where else did you find Solus KH23 available ?
