The rear tire on the left is a replacement stock HD Street Bob Dunlop tire.
The rear rire on the right is a radial. I think it is one size smaller on width. (Same stock wheel.)





I'm thinking the radial rear tire looks too skinny.

The guy that put radials on his Street Bob isn't pleased with the way it handles now.

 

I don't recognise the radials, what brand are they? Some tyres are better suited to Harleys than others.

 

The markings on the sidewall say DUNLOP TRAILMASTER. The owner tells me they are radial tires. He also says the handling has improved back to original since he adjusted the shocks for more pre-load last night. His opinion is that the radial tires are more sensitive to having the suspension set up exactly right.

He is much happier with the his new tires now, but not really pleased with the skinny look of the rear tire.

 

Man I'm not lovin the tread pattern on the replacement tire. It just looks out of place on that bike.

 

Those are duel sport tires and look like D607s, WTF?
