New dark side with SideCar

I have a 2006 1800 S3 with CA side car. Followed the directions on this site. Sealed spokes on rear tire with 3m 5200 marine and mounted a 205/65 15. Have been running for two months 3500 miles up to 85 MPH. Could not be happier. Every thing is great. No leaks, rides great. Tire shows no wear what so ever. Ran through three MC tires in 16K miles. Speed-o is just slightly fast but was fast before. Just keeps me from running even stupider. I have a heavy foot no mater what I drive. Did try the GE silicone first but it failed miserably, did not make it to end of street. B roke down the tire and pulled the silicone out like a one piece rubber belt. Thanks for the great info.
