I'm getting new tires in March and have done some digging in the forum archives. I've determined that I really like the look of the vintage tires(ex. Firestone. Are these option s that the dealership can offer or do you get these tires put on at a Indy ?
Dealers tend to only offer Harley approved tyres, in my experience. If you want to fit any other brand, modern or older style, you need to shop around. I actually use my local Yamaha dealer, because they are close and will buy in most brands and fit to a loose wheel.
You can check at the dealership, but I'd go with an indy. My local dealership wouldn't even get me the Michelin Commander II tires that I wanted. I was told they only sell and install the Dunlop and Michelin tires that had the HD logo on them. They won't even do just an install on tires that I carry in. The guy in the service dept. tells me this right after complaining about how slow it's been the last couple months.
+1 on Indies. They may do a deal for you on other brands/styles of tires & will mount them cheaper. I actually use a local Honda shop to mount tires I buy online, and they only charge me about $20 a tire/rim to switch the old to new. The HD shop said minimum of $90 for me to have them switch out the front & rear tires even with me bring them just the old tires/wheel & new tire for them to switch out & them not remounting/aligning them back on the bike.
