Topic: scalloped rear tire

[jsaab2748]

My k5 750 is starting to develop flat spots all the way around the tire, that can actually be felt thru the entire bike at very low speed. The tires are a matched set of dunlops, but the type/model escapes me right now. Both tires were replaced at the same time, and both wheels were checked for trueness and statically balanced. Rear shocks are Hagons with maybe 8000 miles on them. Anyone know why a tire would scallop? Is it maybe an alignment issue
due to the wheel being mounted crooked in the swing arm after a chain adjustment? At this point, I don't think the flat spots can be eliminated, but I'd at least like to keep them from getting worse. Is there a preferred method of wheel balance you all would recommend?
As always, thanks. jim

If you mean your tires are cupped its usually caused by not keeping the proper air pressure in the tire low air pressure is the major problem you need to checkk your tires on a regular basis and keep the pressures up.  And you are right once the process of cupping starts there is no stopping it, you will need to replace the tire. Sorry

What joeb said. Once cupped they are toast. Softer sport touring tires are bad for eventually cupping . I've never had a rear tire cup though, always the front.

Been riding 2 up lately, never adjusted for that pressure wise, but it's pretty close to spec
for 1 up riding (according to the owner's manual). Do you guys use maximum recommended pressure from the tire manufacturer, ar the max. pressure that Honda specifies?

For tire life I'd go with the higher of the two. Depending on the  bike, riding style, weight, braking habits, tires etc sometimes they'll cup anyway. Big problem on Oilhead Beemers.

I would go with manufacture's specs the closer to to the high pressure the better unless you start to loose handling.  I use Dunlaps on my wing and if you run low pressure they will cup.  Hope this helps.
