    I am looking for front and rear tire recommendation for a 1985 ZL 900 A1. Please let me know what manufacturer and tire type that have worked well for you on this model.

    Thanks in advance for helping me out with making this decision.

    170 is max width for our rim without squeezing the tire changing the profile and handling characteristics from what the manufacturers intended the contact patch to be. That said there are people that want wide and it will effect handling but look tuff.
    Shinko Tourmaster is best bang for the buck. Metzler compound seems hard and lord help ya in the rain. Avon was great when new and it was greasy at 1/2 tread. Not many to choose from in 170 and even less in stock size of 160.

    I'm satisfied w/ my 170 HEIDENAU (German brand) which has enuff clearance in the swing arm, could even go wider a bit to 180; in the 'Nice shocks thread' you can see a 150 MAXXIS chosen by Michel, but he said 170 won't fit even w/out pressure in it, looks like some tires come out bigger from vulcanizing than written on the side...

    I just came from Iron Pony where I bought the Sinko 230 tourmaster 100/90-18 $55 for the front and 170/80-15 $86 for the rear, I had the front wheel off and they already mounted and balanced it for me. Once I get the forks done and front wheel on, I'll take the rear wheel in, they charge $28 to mount the tire and balance if off the bike, a lot more to remove from the bike.

    60 sidewall profile on a 15" rim is too small for the zl and would look awful. You too used to shopping for 17" rims there RJ.

    :hello: The stock tire size on a ZL 9/10 is 160/80-15 so the Michelin Pilot tire would work perfect. I put a 120/70-18 tire on the front of my ZL 10. After mounting it it still measured only as wide as a 100/70-18. The rims width determines how wide a tire will be after it is mounted & not the tire size. IMG_5993.JPG IMG_5994.JPG A far cry from being a 120. The tire tread is riding up on the sidewalls. This causes the tire not to perform as it should.

    The tire you posted 160/60 15 is 2 1/2" smaller OD than stock 160/80 15. Not a proper tire for the ZL.

    The middle number (sidewall height) is a percentage of the width. It's a scooter tire like the link says.

    :hello: That means that it has a lower profile & the width is still a 160. Scooter pooter. :laughing7:. It will still work better than a 180 because with a 180 mounted on a stock 15 " rim the tread rides up the sidewalls giving less tread to the ground. My rear tire is a 180/55-17. Recommendation from the manufacture is 190/50-17 or previous said size tire.

    Tire OD = Rim Dia + (2 × (width×sidewall height))

    Sidewall height is stated as percentage of width

    15" = 38mm

    160/60 15 = 381mm+(2×(160×.6)) = 573mm OD = 22.56"

    160/80 15 = 381+(2×(160×.:cool:) = 637mm OD = 25.08"

    Your 17":
    180/55 17 = 431.8+(2×(180×.55)) = 629.8mm OD = 24.80"

    160/60 15 = Scooter tire not to be used on a ZL

    170/80-15 = 381+(2x136) = 653mm OD => 25,71'' :laughing7::hello2:. Best ratio up to 200 (which won't fit...)

    :hello: Yes I know about how the math works but a tire is not perfectly round all the way around. So the math is not set in stone. Also the O. D. is measured at the center/middle of the sidewall. When looking at a Michelin Pilot Road 3 or 4 tire the tread on each outside edge is out past the side walls & say a shinko's is not. I ordered a rear scooter tire for my stock rear 15" rim. :laughing7:. How come that blue smiley pops up instead of the number.

    The blue smile was a fat finger typo. Should have been .8

    The point is the tire you posted will look silly and throw off the speedo as well. It's a sad day when I find out scooters wear the same width tire as the big zl's, they once we're the bikes that wore the fattest tires.

    Not sure what you mean there harriminator maybe the aftermarket shocks got in the way of the 170/80 15 but tons of people run that size.

    John, the thread turned into crap. Hope you found tire info on other threads useful. Rest assured 170/80 15 will fit your stock bike.
