What about a tire survey?

[Grumpy Goat]

I used to have similar mileage when I rode the ROAD 4's (or was it the 5's?) but (a) the fronts wore out slower than the rears (which is normal) and (b) they were pretty scalloped but the time they were changed out.

Since that time, I switched over to my go-to tire for the RS, Dunlop Roadsmart III / IV, and both variants exhibited zero scalloping under same rider and riding conditions. Mileage is about the same and dry/wet performance is similar. Air pressure drops are similar to the Michelins (which I would expect since that is a mounting / valve stem issue). The Dunlops are also cheaper. Loved the Michelins but I found these Dunlops were a much better value.

How are you on the front brakes? I am somewhat hard on my brakes when on a spirited ride so I wonder if that has something to do with it?

On the RS the brakes are partially linked, so when the front brake lever is pulled both brakes are activated, unless you press the rear brake pedal at some point. The system dynamically adjusts the braking effort, but it typically apportions about 70% to 80% of the braking power to the front wheels and 20% to 30% to the rear.

I typically use this feature 99% of the time.

On my Tiger which does not have any degree of linked brakes I use the front brakes (only) 90% of the time and essentially only use the rear brake sometimes when mid-corner and usually when coming to a stop at a light (I like how it keeps the bike level).

Point is, I am not usually hard on my front brakes as I prefer a smoother riding approach, using engine braking as much as I can. Brakes and tires last much longer that way.
