I need a new rear tire for my bw80. Does anyone know where I may be able to find one? Closest I can find is a 18x7-7 but I dont want to make my big wheel tires smaller!

The KT587 is the stock rear tire and there is ONE place online that says they are in stock for $103. I have emailed them to see if they truly do have them. If I could find a pathfinder that is 18x8-7 I would like to get one, but I can only find them in 18x7-7.



...and of course i've tried google

Your googlefu is weak. All the above claim to have at least one Dunlop in stock. Prices start at high-60s. Wise to verify availability before sending money--most online sources order from Tucker Rocky or Parts Unlimited AFTER they get your money. Might be wise to verify and order over the phone due to limited supply.



I checked with the folks at Greenball. Cheng Shin, Kenda, and Dunlop have all discontinued any tires in the 18x8-7 size. Better get a lifetime supply while you can.

Thanks qwerty. I have checked these sites and they all seem to be out of stock as well as many other sites
Should I be trying to find an 8" rim so I will have options down the road?

Ok. I'm leaning towards buying a taller rim so I will have tire options down the road. Can anyone help me figure out how to do this? As of tonight all I know is the wheel is 8" tall and has three mounting holes.

I did find a few 19x8-7 duro atv tires for about $50 a piece. Would that mean the tire is 1/2" closer to the fender. If so, I would think there is enough room for that to work.



I did see that someone raised the rear end by making this-

Measure the wheel mounting bolt circle diameter, the diameter of the bolts, and the distance from a straight edge layed across the bed of the wheel on each side to the mounting surface (side that goes against hub). "Offset" is simply the difference between the mounting surface and halfway between the beads. You can determine your offset easily. If the mounting surface is the same distance from both beads, you have "No" or "0" offset. If one bead is 20mm closer to the rim than the other, your offset is 10mm. If the mounting surface is closer to to the hub side bead, you have positive (+) offset. If the mounting surface is further from the hub side bead, you have negative (-) offset. By knowing the offset, you can select a wheel that has a different width between the hubs than stock and still keep it properly centered in the swingarm.



Calculate the difference between the distances from each bead to the mounting surface and divide by 2 to determine the "offset".



Running an inch taller tires certainly wouldn't hurt anything if they clear the hard parts. You'll probably want to run a bit larger wheel sprocket to compensate for the taller rolling radius. Don't assume an inch taller in the size designation translates to an inch taller tire or a 1/2-inch decrease in clearance. That idea "should" work, but often doesn't.
