During my 'just-finished' 720 mile ride thru S and SE AZ, I got a bit tired of hearing my Tourance 130/80 (rear) on the front of BIG RED "HOWLING" at speeds above 50, so I planned to remove it and install the SHINKO E705 in the same size yesterday. I, of course, used zip-ties to make the job MUCH easier, took a few pics, and here are some observations:
1. That Metzler was reputed to be 'good' for as much as 36,000 miles by 'Gary' in S America, years ago. Because I only ride my '08 for roughly half the year, it took me just OVER 5 years (09 Feb '12 to 25 Feb '17, w/ a 'break' of a year while I used some knobbies riding w/ "jdrocks") to acquire a TOTAL of 28,799 miles. I measured the remaining rubber, and came up w/ .141" minimum near the center, .271" at the sides.
2. I 'used' the tire to the point that I couldn't see much in the way of "chicken-strips", and it never 'let-me-down', cornering well on pavement and dirt.
3. I was noticing a minimal amount of 'cracking' along the tread-blocks, probably as a result of the FIVE years I used it, and figured I'd get rid of the 'howling' AND 'cracking' w/ a new SHINKO.
Some observations on the SHINKO:
1. I've heard the opinions that you should 'reverse' the direction of the tire when you put a rear onto a front wheel, but, like many others (jdrocks, for instance) I have ALWAYS installed them w/ the 'directional-arrow' pointing forward, and that includes the SHINKO on the front wheel of the GREEN HORNET TOO in BC (however, a FRONT 120/70), and used it to Alaska last June. Imagine my surprise to see the 130/80 'sporting' TWO sets of 'directional-arrows', different directions depending on whether it's used front or rear!
2. I installed a 90 degree valve stem during the 'install' (same as I have on the rear wheel) and when checking rotation after, I kept hearing a 'click'. On further inspection I determined that the valve stem was JUST long enough to 'foul' my brake-caliper, so I turned it to follow the direction of the wheel - STILL easier to use than the OEM shorties.
I went for a ride this AM and am glad to report that I did NOT hear any howling...!
I will say that I got VERY good value from however many $ that Tourance cost me.
