After a nail in one of my tires and blowing out another yesterday on a chunk of concrete in the middle of the road I decided to just upgrade all my tires rather than replace the two stock ones. Went with some Goodyear Wrangler Ultra Terrain A/T 33's on my stock 20" rims. Size is 275/60 R20. I have to say... The ride feels like it might actually be smoother than the stock tires. Also, I have little to no vibration, added a little height, and they look amazing. Got 'em for $1200 out the door with a sick replacement warranty included on all 5 for 70k Miles/10 Years. Would highly recommend so far!
