(2) 20x8.8, fronts (2) 20 x9.5, rear. Wheels are polished aluminum in excellent condition. They can use an excellent polishing, however I will certainly take care of it prior to they are offered, for my asking cost. They have Goodyear 275/55r20 with about 60 % tread left. When I bought them, Wheels retailed for $800 a piece. They will certainly fit any 6 lug Chevrolet, GMC, Tahoe, Suburban, Yukon, escalade, Silverado, Sierra, avalanche. Will certainly separate wheels and tires. Dropped the asking cost to $850, requires to get these from my garage, occupying too much space. Make me an offer!
