I cant remember what tires I had on two sets back, prolly because I'm getting so damn old. Corsa IIIs barely lasted 3000 miles. I can't afford new tires every 3K miles! I had Erik's minions throw some Rosso IIs on. Loved the feel. But they are showing cord after barely 4500 miles. Now I haz a sad, was hoping for considerably more. Okay, the SV is a bit tough on rear tires and I do like to get the most enjoyment possible from the torque monster it is and that doesnt help the tire last. But come on! There must be a tire that rides great AND is less wearing? Don't need a new front so I'm torn on spending money for two new tires versus one new Corsa, depending on what I can expect. So for those who ride a big bike and ride it ... spiritedly, how you doing - Bike, tire, mileage? And who has the best rates in PDX area to mount and balance (wheels on the bike cause I don't have stands)?
