Default Rear tire project on '90 softail

Ok heres the deal. Im stuck in Iraq with alot of time to figure out how to tinker with my newly aquired (bought off ebay) softail.

I've searched the web for a fatter tire kit. Came across DM Customs kit. Being the guy that I am I think I can do it better for less. So far Ive come up with this. Im going to use a 2000 softail swing arm. Run a 18x5.5 rim and maybe a 180-200mm tire. I want to keep everything else stock, accept the fender and fender mounts. Any one got any idea as to what size spacers I might need? Or any other tips that might save a guy some a$$ pain later. Or just any other cool tips on an old evo.

-Joe

i have a 1990 softail also. didnt know you could swap out the swingarm for a 2000 model. but how does that affect the rear drive belt, right now, with a 160 rear, im 1/4 inch away from the rear drive belt.

From what the dude at DM Customs tells me, a 2000 or newer swing arm will allow a 18x5.5 rim with a 200mm. I don't know that the swing arm from a '06+ would work though. They didn't say anything about offsetting anything. It will require removal of the horns on the back. And some spacers.

Get a strutless fender, it will make your life a lot easier. The only difference on the 2006+ swingarm is the caliper mount has been shaved. You will need a narrower belt or most likely a chain if you go with the 200mm.

Sgt Lopez, I looked at the DM set up from iraq as well. Not sure about your 90’ but I have a 99’ night train that I put a 180 metzeler on using the stock swing arm. Im running a 18 X 5.5 inch rear wheel with a strutless Russ Wernimont fender. Had to cut the frame horns off. I used a 70 tooth ž inch pulley and a 2006 HD 133 tooth belt. Needed new rear spacers. Because of the 70 tooth pulley I could no longer use my belt guard so I cut the off the tabs. I think I like it better anyway. Good luck

I have a Metzler tire chart if that will help. It has the mods for larger tires. I can email it if you pm me with your email address.
