I am replacing my Metzer tires with Bridgestone front and rear. I have a 2002 LT. Am I making a good decision?
I love the 'Stones. I've run Avons, Metzeler, and Bridgestones during the 90K+ miles I've put on my 2000 K1200LTi. A great many of those miles were on climbing and twisting roads in the hills and mountains of Vermont.
The front will wear out before the rear and won't last long. I was putting on a new set of tires every 6000K miles when I did a scheduled "BMW Service" or "Inspection".
We are not riding as much as we used to (often ride two up), nor riding as aggessively as we used to. BUT, there was nothing like the feel of the bike in the twisties with a new set of Stones. The bike exudes a grippy confidence with the Stones that the Metzlers lack. (Our riding style was that of trying to go fast, not maximize tire mileage.
As far as those who recommend a tire mix, I have no argument with them; these are experienced riders who have arrived at a solution that works for them. However, I've always stuck with a matched set of tires. I once had a really weird experience with a mixed set of tires. I've forgotten what the exact mix was, but the mixed set handled great for hundreds of miles, and then one day it got bad. Some combination of road surface, temperature, humidity, or whatever and they got really squirrely. I ruled out tire pressure, road/tire contaminants, etc. Ahh, I thought to myself, that's what tire manufacturers are talking about when they recommend against mixing brands.
So if great handling, and confidence in the bike's traction on all kinds of road surface, the Bridgestones are a great choice. They are not the best choice if you're most interested in high mileage.
Addendum: I did run a couple of sets of Avons, I found them to be more like the Bridgestones both in terms of better grip and lower mileage than the Metzlers. But I didn't think there was any big advantage of Avons over Bridgestones.
