I just installed a new Metzeler on the front today.
It sure feels like a new bike. Amazing what a new front can do.
Got 16,000 from the old one.

Know what you mean, new skins front and back, feels like a new bike.

Got a little over 20K on the front, it was cupping. Rears don't last as long, less than 10K.

Trying a new tire combo, Metzeler in front, Bridgestone in back, feels good. Have determined that an Avon Storm is not a good tire for the rear.

Whew! You had me worried there, Jesse. I thought maybe you ditched the LT.

Good deal on the new front tire. I never got that much out of one.

No way, Howard......

She's a keeper. Too good a ride 2-up. My wife
wouldn't let me get rid of it. My youngest son
has claimed the pillion, as soon as my wife
gets her Spyder.

I'm running the same combination. Put the first BT on
3,000 miles ago. I was hoping for some extra miles
from the Bridgestone. The ride is great.

Here must be someone on this forum who is wearing Wellingtons on the left and flip flops on the right foot :rotf: .
Why do you put different tires on front and back? Can give someone a explanation to that?
This is dangerous, because your bike develop a different behaviour front to back.
Please dont take this wrong, everyone should know what he is doing but dont play with your live.
Here in Germany it is even forbidden by low to use different tires on that bike and this has a reason.
So be careful dont play with your live.

I've been running Metz.880 front & Bridgestone BT020 rear for over 100,000 miles. What difference can it possibly make. Both tires are OEM tires for the K1200LT. Both tires are Bias Ply tires. Even if you run the same brand of tire front & back the tread is completely different.

I can guarantee you that the bike & suspension can't tell the difference. This is the best mileage combination for front & rear tires that a lot of us have found. This combination has the best equal wear front & rear. In my opinion because the front & rear tires wear equally it is a very safe combination. On my 2000LT both front & rear tire are just now at the wear bars at almost 18,000 miles.

Ok, you Guy's should know what you are doing. Maybe a mixed pair is good enough for straights and up to 80 mi /h and I know a lot of LT owners do this in the states.
In the German Papers to the Bike it says " Reifenpaar nur von einem Hersteller zulässig" translated "Tires front and rear are only of one manufacturer permitted".
If Police stops me with a mixed pair of tires over here they take the bike of the road.
Once again please don't take it as a criticism from my side on that what you are doing, just wonna let you know it is not safe even if you mean that.
There change also 100 k mi not my mind, sorry.

I like the metz on front and after running the metz on rear a few times I just installed my 2nd brigs on the rear. Does not get as noisy as metz and have also got more mileage from the brigs. Brigs was quieter when in turns when worn out then the metz was with 8k on it.

I also run the Metzler on the front and the Bridgestone on the rear. I works like Saddleman said. The Metzler on the rear wore out faster than I thought so I found a Bridgestone at a better price and thought I would try it. I can't tell the difference other than I get better milage with the Bridgestone. The Bridgestone front on the other hand wears out faster than the Metzler so I keep the Metzler on the front.

I think you are confusing "known to be safe" and "known to be unsafe" with "safe" and "unsafe."

Manufacturer's include statements like the one you reference due to the fact that they simply don't have the resources to rest all possible combinations of tires and such that owner's may choose to install on their bikes. So, they test one combination thoroughly and then approve that combination as being safe. This does NOT mean that other combinations are not safe, it just means that no testing has been done and thus it is not known if they are safe or not safe.

Unless you have tested another combination of tires and have data that suggests that combination is somehow unsafe, you can't proclaim it unsafe simply because it is not the safe combination the manufacturer specifies.

There is a similar issue in the aviation world. Most certified airplanes have a specification called the "maximum demonstrated crosswind." This is required by the FAA to be at least 0.2 x Vso (twice the power-off stall speed). The manufacturer has to list this speed and it must meet the FAA minimum, however, the actual cross wind component that a given airplane can handle may be much higher than either the FAA minimum or the value "demonstrated" during flight tests. The demonstrated value is simply the capability that the manufacturer had the time and resources to demonstrate. It may be that they simple didn't have time to keep testing until they found the ultimate limiting wind speed.

So, if you attempt to land in a cross wind greater than the demonstrated amount, you are now a test pilot. You may well be successful, but you are operating in a regime that the airplane has not tested. Same with mixing tire brands. Any given combination may well be very safe and perform very well, but you are now a test rider for BMW as you are exploring an area they likely did not explore.
