It seems that most forum members discuss tires which fit other bikes but not the new K1600. In fact, there seem to be a pretty small selection of sport/touring tires in the above sizes, so far.

Here's what I've found:

:: Specs :: DUNLOP - SPORTMAX Q2 - Bike rated 3/5 stars -

Michelin Motorcycle Tires - Bike review 3/5 stars - Always good performer, especially in the wet and over long distances.

Michelin Motorcycle Tires - Bike only tested them in the rain and said they were sensational.

METZELER - Product Features - Ride review - "Grip levels still fine even on heavier bikes." ... a rear should last 8000 miles while still delivering the kind of grip that exceeds the ground clearance of all but sport bikes in the dry." Bike review 3/5 stars - Easy turning, confidence inspiring, do-it-all sports touring tire.

Continental Motorcycle Tyres*-ContiRoadAttack 2: Our masterpiece in sport touring. - Bike review 3/5 stars - Softer, sportier replacement for the Road Attack ... faster wear.

http://www.bridgestone.com/products/motorcycle_tires/products/battlax/bt015.html

http://www.bridgestone.com/products/motorcycle_tires/products/battlax/bt016.html - Bike rating 2/5 stars - Solid enough road tire.

http://www.us.pirelli.com/web/tyres-catalog/moto-hypersport-none/en_US/DIABLO%20CORSA%20III%20Three%20zone%20compound/default.page

What is hard to tell is which tires are designed for the weight of the K1600GT, let alone a fully loaded, two-up, GTL.

What else is there?

The Metzler Roadtec Z8 and Michelin Pilot Roads look like good choices for the K1600s.

I've always run the Metzler Z4 and then the Z6. When I find something I like I stick to it.. The Z8 should work just fine. I hope my GT doesn't come with the slipstones.

Just so happens I have a spare set of Dunlop Q2's which were previously intended for the S1000RR.

Only lasted about three track days. Hopefully they will last a bit longer on the GTL. :)

I've been looking at the popular tires for the K13GT and expect that we will see the BT-023 GT and Roadsmart come out in the K1600 size soon.

Here is a summary of the Bike rain tire test:
1. ** Michelin Pilot Road 3 - 5/5 - The best road tire in the wet
2. Dunlop Roadsmart - 4/5 - Three years old but a brilliant road tire
2. (equal) Bridgestone BT-023GT - 4/5 - Good but less sporty than the Dunlops
4. ** Michelin Pilot Road 2 - 3/5 - A good all-round tire
4. (equal) Pirelli Angel ST - 3/5 - Only for those who prioritise stability
6. ** Metzeler Roadtec Z8 Interact - 2/5 - Quick, but dosen't inspire confidence
7. Avon Storm 2 Ultra - 1/5

** indicates K1600 sizes

Hey...

I checked at SWMoto and REVZILLA, and none of them have been able to give me a clear 'verdict' on whether the Pilot Road 3s come in a version that can handle the 1600GT, weight wise.

You see, I used the PR2s on my 1200GT, with the 180 in the back being their 'B model,' capable of handling the higher weight of the 1200GT. Nobody has a PR3 190 tire in a 'B model' listed - but they also cannot answer my questions about whether the 'standard' PR3 190/55-17 will be able to handle the 1600...

Am I missing something? :confused:

According to the Michelin Fitment Guide, the 190/55 max load is 853 lbs, 120/70 front tire max load is 520 lbs, total 1373 lbs.

The published GVWR for the K16GTL is 1235 lbs (560 kg).

There is a greater size availability in Europe, if you can find the tires.

While we have fewer tire choices, availability in the US seems better. And, with no rules or regulations that limit our tire selections, it is certainly easier to experiment with the different tire options.

With the Bike Magazine rating of the Michelin Pilot Road 3, that will be my next tire.

Thanks!

I knew I'd get the answer here. PR3, here I come! :clap:

What befuddles me though is, looking at the load ratings for the PR2, standard and B model, they are identical (365kg/805lbs)?! Now why did I have to use the B model (more $$!), if the charts are correct?! :confused:

Pilot Road 3 Set Ordered

Ordered a set of Pilot Road 3 from swmototires.com for $312 w/ free shipping. My rear Z8, at ~2200 miles has 4.5-5mm tread left.

The PR3's will go on once the rear Z8 is done for... If the PR3s are to the Z8s what the PR2s were to the Z6s on my 1200GT, the comparison won't even be close...

I'll give my 5c once complete :k16:

Bridgestone Battlax Tires ....No Good

I picked up my new GT last Friday and noticed a vibration in the handlebars @ 60 mph. Took the bike back to the dealer and they pulled the wheel to check the balance. The balance was dead on. Checked the tire and found what seems to be a manufacture defect. The dealer ordered a new tire. I would prefer Metzelers on the bike. German tires for a German bike. My RT came from the factory with Bridgestones and they were good handling tires but I only got 7000 miles out of the set. I have had Metzelers on my RT and Goldwing and they have performed Very well.
I'll stick with Metzelers!:)

Don't like my Metzlers so far at 3400 miles. The front has cupped badly to the point that I feel a vibration when leaned way over on smooth pavement. They have an alternating scalloped tread pattern down the center (hard to describe) each of which has developed a 2-3mm step across the groove. I have ridden them hard with not a lot of "straight" highway miles (the last 1000+ of NorCal curves with my wife on board; 300lb total weight between us + luggage) but 3400 miles seems a little early for this much wear.

I used to get cupping on my Z4's and Z6's (1994 R1150RS), and I believe it was from running slightly under inflated. I've run my K1200GT at 42PSI and have had no problems, despite it being a heavier bike.

Religiously kept the pressure at 42psi front and back, per the manual. Double checked onboard monitor with two different electronic gauges. For this last two-up trip, I dialed it up 1 psi to 43.

I've had a lot of different Metzlers over the years and experienced cupping on every front. I got vibration and an annoying buzzing noise. I've had Stones on my FJR for the last 3 sets, and no cupping.

On my 1200GT, the Z6s I had mounted were cupping really badly as well. The PR2s I ran after that never did...

RL - I believe the "official reason" for the PR3s not 'BMW-sanctioned' is that they don't have a 'B Model' in the required size. Claim is that for a "heavy sport touring bike' like the GT/GTL, the sidewall needs to be reinforced, which is the only difference between the standard and B models (other than price, of course).

I ran with standard (not B model) PR2s on my 1200GT for over a year and a half (3 sets), although my last set had the B model in the back - frankly, I couldn't feel a difference. Maybe if you run with a heave load in the panniers and topcase, plus a passenger, the sidewall could be an issue... :confused:
