Can someone please give me some feedback / guidance on just how big of a front tire & rim you can run with a stock 2011 Street Glide fender without having to make modifications?

 

Im running a 19" on this one i have been told you do a 21" by drilling the fender holes a lil bigger

 

Here is an excellent chart.

you can use the 21x3.25 with a 120/70/21 Metzeler ME880 front tire. We have installed tons of them on the newer baggers and MOST of them did not require any fender modifications at all. We always do a simple spin check while the front wheel is up to check for any fender/tire clearance issues. If you have any issues, it's usually toward the rear of the fender. If there is an issue, you can simply drill out and enlarge the rear fender mount holes and tilt the fender forward. The ME880 tires do not grow or swell with heat/riding, so that is the tire we recommend. Call me if you have any concerns 972-231-1298

thanks
