Spikes Spider Sport SPM 14.321 winter traction aid set Bought and used a couple of times on a dirt/gravel driveway for my Toyota Prius (tire size P195/65R15/wheel specs: bolt pattern 5x100, center bore 54.1, hardware 12x1.5 lug, offset 35-48mm). These are compatible with many vehicles; please confirm the correct sizing for your vehicle at the company website. The website also has videos, FAQ, etc. on using the product. These are so much easier than installing traditional chains, and made all the difference in the traction for my FWD Prius during poor road conditions! $150 OBO plus shipping based on your location (UPS Ground or USPS Priority Mail: 12" x 15" x 18" box weighing 20lbs shipped from 69341 USA)
