Mitchleeey, does your rim run true (it should being cast), or have you dented it. Easy to tell with wheel in the air spinning.
Hi M. Sorry to hear of your woes. 9k doesn't seem like a lot of distance. I just had a quick browse on forums and wheel balance can cause it. The problem may also be inside the tyre where you can't see it. The tyre may have de laminated. Do you remember hitting a drain hole or something which could have damaged the tyre. Is it tubeless.
What's the brand of your tyre as you can get the odd tyre that wears funny on the front i had it with my night dragon 90/90-21'' on the front of my wideglide and i got less than 8k out of it, since buying my lowrider S the Metzeler cruise-tec has done similar on the front, I am wrapped with the rear Cruise-tec as as now done 12k with a little live left in it (i have never had a good performing tyre last this long
Not too many 21” tyres that are designed for the weight of a Harley.
Hi there. Any outcome in this. Did you get a new tyre.
