This is my first thread, hope I do this right. I need help picking out new tires. I am a new rider a don't like how the Dunlap's (402's) ride. I have 02 Softail Standard, with a Superbrace fork brace and progressive front springs stock height. I like to try Dunlap's E3 but they don't my size 80-90-21.They do make a tire 90-90-21, will that fit? With out problems! Or do Avon or Metzler work better on this bike. Like to find a tire that helps me ride better. I HATE tar snakes! Thank you for input and help.
