After doing some more research, I decided on forgoing the Metzeler 150 because it will be too wide to fit. It's 19mm wider than stock. I decided on a 130 Metzeler instead, which is still 142mm, so a little bit wider. Metzeler doesn't seem to make a 140 front that will work, which would have been nice.
I just bought a 21/140 metzeler for my ride wright fat 50. But since RW sent me an 18" rim instead of my 21" I am left to wait until it arrives, maybe next week? My bike is sittin on the wrenches lift waiting to mock up a fender bracket to mount the stock fender. Waiting sucks ***!! I am not very good at it...
I remember the original thread and I will be fitting a 150 on the front and 210 on the back I do remember him saying he had to pull the fender slightly to get it in
I'm running a Dunlop 150 on my front. Stock rim, no modifications to fender. Rides fine to me.
Im thinking to try Metzeler ME880 Marathon Front 150/80/16 as front tire on the crossbones. instead of 150/90/16. would probably be fine coz the tire is less taller than stock, no? Im also running a lowering kit on the back so it should be fine, I guess. what do you think? should I go for it?
