Anyone know the biggest rear tire you can jam under a stock Road King Classic?

 

Sorry. The bike is a 2003

 

I'd say a 150 unless you change the pulley and belt. I run a 150 on mine and it just cleared.

 

150 on my 01. Rubbed the inner (rubber) belt guard. When I backed up a few feet the tire would "grab" it and roll it up onto the top of the drive belt, where it would stay once I got rolling forward again. Had to trim an inch or so out of it.

 

This may sound stupid, but what is the advantage of a wider rear tire? My stock rear wide whitwall wore out at about 13k and isn't a bigger tire (which cost more) going to wear out around the same mileage? Just curious.

 

I got a 140 Avon venom on mine and it just barley touches the strip , rides and handles completely different than the stock Dunlaps

 

what is the size of the rear tire. mine says mu85B16 and thats fine if you want to buy a dunlop but what is the official number so you can order other brands?

 

For those of you that have installed a larger tire - what did you do about the speedo? Unless you install a lower profile wider tire the speedo is going to be out and I haven't had any luck getting the stealer to adjust mine to correct the 5 mph error it has now.
