Just a selection of tyre reviews I have found on various web sites. Hope this helps anyone struggling for choice...

Begin of 1st tire review

--------------------------------------------------------------------------------

This is an extract from ENDURO-WELT 94, a Special edition of MO mc- magazine. The tests were made in cooperation with the mc-magazine "motorrad, reisen & sport" and the ADAC, that's the german automobile club (like AAA in the US), which also has a mc-division. They used lots of equipment for the test, and the report features nice pictures, such as a GS loaded with tons of measuring stuff and fastened to a rail that helps the tester in not dropping the bike while emergency braking on wet roads. Another cool pic is that of Four Black and Yellow GS's running through a curve two-by-two at high speed.

To avoid cheating, they bought seven sets of each tire anonymous at official dealers for the tests. The driving behaviour was tested on a special tire test track and in a moto-cross area. The straightline running at high speed was tested with full luggage (Bags etc.) on the Autobahn. For measuring tear and wear they drove overall 45.000 km through Europe.

The ratings are given in the "german way", that means 1 is the best and 5 the worst. I will quote these ratings first, and the stated conclusions after that:

Dry Wet Dirt Noise Wear Overall
Avon Gripster AM24 2.5 3.3 2.0 3.7 2.5 3.0
Bridgestone TW47/48 4.0 3.2 3.0 2.0 2.4 3.2
Continental TK60/70 2.6 3.0 3.5 3.3 1.5 2.7
Dunlop Trailmax 2.5 2.9 3.5 3.0 2.7 2.9
Metzeler Enduro 3 2.7 2.4 3.0 4.0 2.9 2.8
Metzeler Enduro 4 2.3 2.5 3.0 3.2 2.2 2.5
Metzeler ME33/55A 2.2 3.1 4.0 3.0 2.5 3.0
Michelin T65 2.5 2.8 2.0 2.2 2.9 2.6
Michelin T66 2.5 2.6 2.5 3.0 2.5 2.6
Pirelli MT50 2.6 2.9 3.0 3.5 3.2 2.9
Pirelli MT60 2.5 2.4 3.0 3.0 3.6 2.9
Yokohama E705 2.7 3.3 3.5 3.3 2.2 3.0

Avon Gripster AM24:
Best ratings off-road, worst on wet roads. At two tires parts of the profile blocks flew away.

Bridgestone TW47/48:
Quietest tire in this test, Very bad straightline running at higher speeds on dry roads, even without luggage

Conti TKC60/70:
Lowest wear and tear, else average. Good braking abilities on wet roads, quite cheap.

Dunlop Trailmax:
Allround-tire with average ratings in all points.

Metzeler Enduro 3:
Best and fastest on wet roads of all, noisiest tire in test, can get spongy in curves at high temperatures (but not dangerous)

Metzeler Enduro 4:
Best allround-tire in test, highest speed on road track test. Quiet low wear and tear.

Metzeler ME33/55A:
Best ratings on dry road, nearly unusable off-roads, 2nd highest speed on road track test.

Michelin T65:
Best ratings off-roads. Good braking abilities on wet roads.

Michelin T66:
Allround-tire with average ratings in all points. Expensive.

Pirelli MT50:
Allround-tire with average ratings in all points, but two of the tires formed cracks during the test.

Pirelli MT60:
Best rating on wet roads, most Wear and Tear of all tires, two of the tires formed cracks during the test, can get spongy in curves at high temperatures (but not dangerous). Good braking abilities on wet roads.
Yokohama E705:
Worst rating on wet roads, rear tires did not pass the high-speed-test two times. Low wear and tear.

Overall they recommend the Continental for people who want to save money (Low price, lasts long), the Michelin T65 for Off-Road use and for mostly street use the Metzeler ME33/ME55A. The best allround tires are Dunlop Trailmax, Metzeler Enduro 3 and 4 and Michelin T66. These seem to fit the best for the universal use Enduros are made for.

Begin of 2nd tire review

--------------------------------------------------------------------------------
The following is a translation of a posting from (thomas@atlas.physchem.chemie.uni-tuebingen.de) that he sent to a german mc-newsgroup (Don't remember which one).
This information was collected from the magazine "Enduro" in 6/93, where they tested these tires on a BMW R 100 GS (Tire sizes 90/90-21 T and 130/80-17 T)

Test results (shortened):

BARUM ED 9 T
very cheap, good street-tire, but a little spongy in curves, runs straightline even at higher speeds, good "Grip", but it smears/fills up with dirt and mud easily at off-road use, quite high wear and tear, easy installation

BRIDGESTONE TW 47 /TW 48
difficult installation, average behaviour in curves, average on wet streets, not stable at high speeds, long life expectancy, relatively cheap, average wear and tear

CONTINENTAL TKC 60/70
easy installation, good street-tire, runs straightline even at higher speeds, good on wet streets, rear tire good for off-road use, average wear and tear

DUNLOP TRAILMAX
for universal use, easy installation, good street-tire, good handling, runs straightline even at higher speeds, good on wet streets, not as good on dirt tracks, average wear and tear

METZELER ENDURO 3 SAHARA
very good for higher speeds, runs very straightline, good/safe on wet and dry streets, extremely good on dirt tracks, outstanding braking capabilities, difficult installation, best compromise between street and off-road tire, average wear and tear

METZELER ENDURO 4
unusable on dirt tracks, extremely good street-tire, runs very straightline even at top speed, in curves as good as street tires, average wear and tear, quite expensive

MICHELIN T66 / T66 X
bad street handling at speeds over 80 mph., not too good on dirt tracks, Doesn't like grooves in the street, lowest wear and tear

PIRELLI MT 60
very soft, best street handling, fantastic handling in curves, good grip, runs straightline even at higher speeds, not as good on dirt tracks, highest wear and tear, quite expensive

YOKOHAMA E 705
good dry street-tire, more difficult on wet streets, runs straightline, bad on dirt tracks, very low wear and tear (nearly as good as the Michelin, and lasts longer due to higher profile)

Begin of 3rd tire review

--------------------------------------------------------------------------------
This tire review is not really a test, but a part of a R 100 GS long distance test (Well, sort of LDT, because they only drove 30.000 km and this is not a long distance for a GS :-)). It is from the MO Motorrad-Magazin in November 93. They used different tires during that distance and reported about their experiences. Since they had a model '88, which didn't have the improved frame of the later versions, some of the tire-wobble they had can be caused or at least been supported by the frame (especially at the higher Autobahn-speeds we are used to go at http://www.horizonsunlimited.com/ubb/wink.gif).
METZELER ENDURO 3 SAHARA
Very loud when running on the street, with worn rear-tire the GS becomes slightly unstable especially at higher speeds. Very good on dirt tracks, best combination between street and off-road tire, quite high wear and tear.

BRIDGESTONE Trial Wing 41(front)/42(rear) Not as noisy as Metzeler Enduro 3, better handling, good on dry streets, average behaviour in curves and on wet streets. Neither good nor bad, just average, but relatively cheap

DUNLOP TRAILMAX
Better handling than Metzeler Enduro 3, no negative change in behaviour with worn rear-tire. On wet streets as good as Metzeler, but not as good on dirt tracks, average wear and tear. Good for street use.

MICHELIN T66 / T66 X
Expensive. Very quiet, very good street handling, very good grip on dry and wet roads, low wear and tear

PIRELLI MT 60
Very soft rubber, best street handling, fantastic handling in curves, excellent grip on wet and dry roads, good on dirt tracks if tire pressure is reduced, highest wear and tear

METZELER ME33 Laser(front) / ME 55A Metronic(rear)
Street-tire only, not for off-road use. Quiet, best comfort of all tested tires. Very good street handling, very good grip on dry and wet roads, lowest wear and tear. The steering head bearings have to be exactly adjusted, otherwise these Metzelers become slightly unstable at higher speeds. But this is not critical and may only appear at the older GS's.
