Am planning to run the Dunlop D404 rear tire on the front of my 99 tour. Current tire size is 150/80/17 but I have not been able to find that size in a rear tire. Closest I have found is 150/90/17 in Dunlop and 150/60R/17 in Avon. Any help on where to buy and do they make the standard size for putting a rear tire version on the front?
Why not just use the 404F front in the standard size, It lasts a long time, is a bargain, and I have used it with about any rear tire there is. I like it. I presently have it on my bike with an E-3 radial on the rear. jmho
