The B6 commuter's rear tyre is on it's last legs. Maxxis-something-or-other, done about 7K miles. It's squared off, but still legal tread. At speed I'm getting that weave again. Since this is an SO commuter I'd really like to get as much as possible out of the tyre. Would raising the rear ride height help at all - assuming that's even adjustable. Or should I just forget it and get a new tyre? I think I need one of those dual compound types.
