I have about 15K on My Kumho Exta 4x's. I rotate at 4-5k and had the car aligned at installation.I don't baby it at all in the corners,and keep it inflated @ 35 Front and rear. and they show minimal wear.I'm really satisfied with them.I run 195's. The last tires were 205 BFG super sport AS,but they were prone to hydroplane and tram-lining...even when new.These tires are pretty good in the wet and really grippy in the dry.I also looked at the general Max tires.I heard they got pretty noisy about 10 k in,so I didn't get them.I dyna-matted the car recently,and removed the roof racks to make it more quiet,so the Gmax seemed like the wrong move for me.I'm sure you got tires already,but maybe this helps somebody else.If I recall...the guarantee's for 35K.Also,wider tires aren't as snow friendly,you're probably better off with the 195's.No idea how these work in the snow.I moved to Florida.
