What about a tire survey?

[36654]

As an example, I liked all the Michelin Road tires I've had on my bikes, but treadwear/life dropped at generation 5 and the prices jumped.  The Dunlop RS4 is similar or better on wear/tread life and the price is lower.

I liked the Pilot Road 4 but did not like the tire life of the 5. Never tried the Road 6.
I like the Roadsmart III but never tried the IV.

The RS4 rear is wearing really well and will do over 10K before I hit the wear bars.  The first RS4 front was a disappointment.  It must have been a manufacturing error.........the location of the center mold seam varied around the tire and there was a slight side-to-side vibration at all speeds.  The second RS4 front has none of that.  If the second front had been similar to the first RS4 front, I wouldn't have considered Dunlop in the future.
