I dont like riding any tire in the rain that being said, I have the EIII bias tires on my 85 now and had them on for about a year.
I like the feel of them, they do make a lot of noise when cornering, I just turn the radio up
Everyone has a different outlook on their choice of tire, I have never used other than Dunlop or Michelin on my Wing so I cant compare with other makes.
My next set of tires will be EIII
I did countless hours of research on tires for my 1500.
The Metzelers had too many reports of tread separations & scared me off. Long story short, all the info I could find got me to Avons & E IIIs.
Once, I actually brought it up at a goldwing group meeting [who all knew wingers from all over] & they had the same conclusion + Bridgestone, so I justwent with the EIIIs. A coin toss between them, for me at the time.
After 40+ years of big bikes &endlesstires over 400k miles, I'd say the EIII/GL1500 combo is the best I've had, so far.
I'll always be looking for something better, though.
Most important is to look at manufacture date 'stamped' in tire, it need to be 4 digits, last 2 digits are the year made.
Tires only have a shelf life of 6 years [this is regulated in the UK, but NOT in the U.S.].
I've run about 10,000 so far on my E-III's since June of last year and have had no problems. Good grip in the curves and I'm not bashful about dragging a peg now and then. There is another thread on this site called "Best Tires for GL1500" That has a lot of comments and a couple of other suggestions for 1500 and 1800 wings.
Good luck and enjoy the ride.
Original set of Dunlops that came with the bike. First rear tire replaced at 900 miles for a nail :X. 2nd rear tire and front tire replaced at ~9,000 miles due to severe cupping. (first summer = 2 sets of tires)
Changed to Metzler ME 880's. Must of had a bad rear tire because the bike wobbled from the day they were put on. Changed them at ~2800 miles. Got tired of the wobbles and the road noise.
Purchased Avon Venom's. Very smooth and quite grippy at first. Got noisier as they wore and finally started cupping at ~17,000 (second summer = 2 sets of tires... a pattern?)
New set of Venoms, rode for 3,200 miles and picked up a screw. Not the tires fault. New Venom on the back only. Rode for ~14,000. Front tire wear getting bad gripping the road edges and grooves. Back just starting to cup. Was on a long trip to San Francisco so I broke down and bought a set of Dunlop Elite III's.
Elite III's so far have been much better than the original set of Elites that came on the bike. Ride well, not to noisy and hold the road pretty well when I take a turn a little more aggressive than the wife likes. She never complains, I can just feel her legs tighten up slightly against me.
In Summary so far I can vouch for the Avons and the Elite III's. I won't put another set of Metzlers on.
