interested in going with a larger tire on my rear end, on my 01 fxdwg,
whats the biggest i can go with out rubbing anything
thanks

 

Not sure what the stock rear tire size is for your bike,but usually you can go up 2 sizes with no problems.Let's say,there is a 160 on there now.You could go up to a 180,max.

 

An 01 Harley dyna has a 130 tire on the rear, could be tight for a 150,

 

I have a 150 in my old Evo, but to get it in I used a later spec narrow belt and rear pulley. I changed the gearing at the same time. I have read that a 150 can be got in, using a narrow spacer behind the pulley, to provide clearance between tyre and belt. That wouldn't work for me, but it seems it can be done.

Be aware that the fitted widths of tyres can vary a lot from the size they are supposed to be. My Avon Venom is actually 153mm wide, on my 3" rim. My previous 140 Venom was only 139mm wide. Some tyre brands have bigger differences (often wider, not narrower!).

Take a look over in the Dyna forum to see if there are any threads.

 

A Dunlop E3 would be a good choice in tires. An MU 90B-16 alpha numeric would be the equivalent of a 140 series tire. A 150 would be a tight squeeze and you would likely have to re- route your rear signal wires under the rear fender to fit the 150 without interference...especially if the bike is lowered. Dunlop also suggests a minimum rim width of 3.50 inches with the 150 tire. The stock rim is 3.00 inches wide so really with a stock rim a MU 90B-16 (140) is the best way to go. I have a Dunlop E3 in MU 90B-16 on mine and it's lowered one inch and I have no clearance issues at all, even when riding two up. You can realistically expect 10-15 thousand miles out of an E3. In 2002 the DWG came with a 150 from the factory, the rear fender is slightly wider and I think the fender struts are also further apart as well.

Interesting how the tyre brands differ. Avon recommend a 3.5" rim, but permit fitting a 150 Venom on a 3". I have done thousands of miles on tour 2-up with one on my Glide, so it works just fine!

 

I'm not sure how critical the rim width recommendations are when you are only talking one or two sizes over the stick tire size. Putting a tire that is too wide for the rim will make the tread surface curve around with the sidewall and you won't get the full benefit of the extra width of the rubber on the road. Even the Dunlop150 wide tire kit HD sold for the Softails that originally came with a 130 rear tire, were installed on the stock 3.00 wide rim while in the Dunlop literature it recommended a minimum 3.50 rim for the 150. I guess Harley Approved means more than Dunlop Approved.

 

Good points! When changing brand of tyre we are on our own, as Harley only recommend Dunlop (at least for my Harleys). Hence I refer to Avon's website and as I have used their tyres on my Harleys since the late 70s, their word is good enough. They recommend 3"- 4.25" rim for their 150/80 Venom, which seems a very range of sizes.

 

Stock Dunlop on my 02 FXD was 130 and I've got a 150 Michelin, .... Commander? I think it is, on there now. But thats on a Duce rear wheel.
