Goodyear's Wrangler SR-A LT215/85R16E 115P Tire Helps Trucks/SUVs Get a Grip Designed to serve as original equipment on a variety of light pickups, vans and SUVs, the Goodyear Wrangler SR-A Tire prides itself on all-season performance and highway quiet. When it's wet outside, the Wrangler excels. It also can go off road or handle itself when conditions start to get a bit dicey. It's designed to reduce noise and rattle on varying terrain, including gravel and light snow, while its WetTrac technology improves handling in wet conditions. For the Wrangler SR-A Tire, and the entire Wrangler line, it's always been all about the tread. Offset tread blocks deliver traction and handling, while zigzag grooves within those blocks smooth and quiet the ride even as they improve grip on and off road. Wide circumferential grooves help quickly move water out of the way and allow you to move confidently ahead in wet conditions without worrying about hydroplaning.
