I have this same problem in my FJ - new bearrings in front wheel new oil in front suspension and nothing...:( what is this? My tire Michelin PilotRoad2.
FastJota Alf, you need to try the RPM front fork valves, that problem will go away. I used to have the same issue on my front tire. Here is Pilot Power 3 tire I took off with 8000 miles on it before the winter months.
I made it and dont help it...new oil and simmerring and nothing...what's up?
FastJota Alf here is my Pilot Road 4 after last winter before the summer PP3 tire above. this tire has almost 12k on it. RPM fork valves work and the tires last much longer.
Te Cecha if the tire is already cupped you cannot do anything with that tire. If you have wear of the fork bushings that can cause the wobble. Also a RPM fork brace helps stiffen up the front end.
Go slow, ;)
Steve Jpnes in mainland Spain, with more straight roads, the problem is not so pronounced: around 8.000 kms. in my FJ front Roadsmart or cupped MZ 8s like your tyres in my FZ 750 with 7.000 kms. In my Fazer 600 a couple of Pilot Roads lasted 4.000 kms here in Tenerife. The problem is that I like to take curves ;)
Fork bushings is ok ...i controlled it when I change oil in fork...:( two tires I killed... - Pirelli Diablo strada and now PR2...and still I don't know where is problem maybe central bearrings in frame?
me too, my daily commute to work includes a mountainous set of twisties that for about 35 miles one way...I get to do that everyday on the way to work and back home. I used to get low mileage out of my tires, but since I changed over to RPM suspension the tires have almost tripled the miles. http://rpmracingca.com/proddetail.asp?prod=M%2FC%3 ARPMForkValve http://rpmracingca.com/proddetail.asp?prod=M%2FC%3 ARPMShock%2891-95%29
