Actually, I had the truck first. It was a stock white (ugh) Silverado, and I just had it painted back, put the SS 20s on it, the tonneau cover and an induction hood. Looks faster than it really it.
Now, back to the Shadow - I got the Metzelers installed. Unfortunately, after about 2 or 3 miles, the rear tire rolled off the rim as I was slowly going around a corner. No damage to the bike, and the shop that installed the tires came and picked it up for repair. According to them, the tube had a pinpick in it, so it held air until there was weight on it. I dunno about that - they gave me the old tube, and I stood on it (aired up), and it didn't leak. I guess it's possible the old tire had a piece of wire in it that punctured the tube but was keeping it sealed. Who knows? Regardless, they replaced the tube and brought the bike back to me (and gave me a certificate for a free oil change/service next time) - all at no charge. Good service.
Oh, and I'm in the deep south - where it's reallyreally hot!
