For some reason my previous post is no longer visible. Call around to small engine repair shops as any of them that deal with Husqvarna can order the tire for you. It took me several phone calls but eventaully I found a place and they had the tire for me the next day. $20 something dollars including shipping. Stay away from Home Depot, Wallmart, etc., as they are not interested and really don't know who to call. Just make phone calls and tell them you want a tire, and don't let them sell you what they have on hand, unless of course it is the exact tire you want. They can just as easily order it for you.
I explained to you above how to get one tire just as I did. Take it or leave it.
If you follow the above advice from Scott, you should be able to get your tire. It took me several phone calls and visits to local "dealers" and finally one of them placed the order and I had the tire the next day. Home Depot seemed like they didn't want to be bothered as did Walmart. So look for local small engine repair type places, they seem to cater to the customer better.
I did google only the part # 532428269 and found 3 results, all Husqvarna manufactured front wheel assemblies (and a Myspace & Facebook link?). But no pictures and the price was a penny more. I'm not sure if I want to take a chance at ordering blindly like that.
I agree with MacArthur Eld, something seems very strange about all the backorders and that no one can order the specific Weedeater One wheel.
