I had Michelin Road Pilot 4's on my K1600 GTL and it caused it to pull left, changed to Dunlop RS4's and the left pull disappeared. I run the Dunlop Trailmax Mission's on my GS and I love them, however they are more of an off road tire.
Just made official complaint on their website. Let's see the answer.have you called the manufacturer, these could be a dangerous issue that needs addressing
Done that already, no change.The most likely source of the problem is the shop. It’s not a balance issue. And probably not a tire issue. If the symptom is as radicals as you describe there is something “wrong” with the set up. I’d ask the shop to dismount the tires and remount them. visually check to see the beads are seated. Something is wrong and it’s probably not the tire and it’s definitely not the balance.
That's an impressive bit of detective work. Well done!Went back to the shop that installed my Road 6. They still had my old Anakee's. I explained I wanted to test my front tire by installing back my old Anakee. As they were informed by me previously about the problem, they said they's do it free of charge and then put back Road 6, free of charge too. So they did, balanced it and I went for a test ride. The result is, the bike was perfect again. No pulling left at all. Then I went to one highway to see about the rear swerving, and that one was gone too. So everything was back to perfect. Went back to the shop, they put Road 6 again, balanced it and I went to the same roads for the test. Bike was pulling left again and the rear was swerving on the highway.
So, I have my conclusions now. It's the front tire.
The guys in shop were very nice and helpful. They also filled complaint to Michelin importer but they say it's hard to get any response from them. They offered replacement tire, whichever brand I wanted but I know them for many years. They are just small family bussiness and very honest. Knowing them and the way they work, I know if I accept the replacement, they would be paying out of their own pocket and then wait for Michelin to refund. And that may never happen. I just can't do that, it wouldn't feel like the right thing to do. So, I won't. I kindly refused the replacement. I'll see in Spring if I can get Scorpions Trail 2.That's an impressive bit of detective work. Well done!
