    Shinko 230s or 712s?

    I know the difference is probably slight…. As is the price. I’m going to put about 1,000 miles on my GS1100 in the driftless area of SW Wisconsin in a couple of weeks, and thought fresh tires would be nice. I have 230s on it right now with no complaints…. But it’s 3 year old rubber… and the rear is starting to get worn.

    On paper the 230 is V rated so it's supposedly better. That said, the 712 has similarly great reviews and is cheaper. Flip a coin?

      I don’t think I’ll be approaching 130 anytime soon.... I pulled the trigger on the 712s. Mostly just to try for myself.... and save $15.

        I've used both. They both work well with no real difference between them that I can tell (I don't get much chance to ride in the wet....). Running 712's at the moment.

          Yep, I've strenuously abused both and I can't tell the difference from the saddle. The price difference is usually something like $5 or $7.

            I have some 712s on at least one bike. No problems. Everything from dirt roads to long highway rides at 85 mph.

              I read that the 230 is more heavy duty touring oriented somewhere. I looked at user reviews such as below and 712 seemed the way to go. I am very pleased for the ones I now have on my GS1000E. It may ruffle feathers but I wish I'd saved money and gone with them on my CB750 and GS1100E, which run Avon AM26s - they are great tires, but hard to find these days it seems.

              Putting an 81 motorcycle on the road, just got it running. One website likes the Bridgestone BT 45 tires, though they do not differentiate H or V...

                When I was piling a lot of miles on my GS850, I did the math and used the Avon AM26 RoadRiders. The rears lasted about twice as long as the Shinkos, and I could run two rears for every front (the AM26 100/90-19 front is also designed to be used as a rear, so it is especially durable). So cost per mile ended up cheaper even though the Avons are ridiculously expensive.

                Nowadays most of my miles are on my other bikes, so I end up replacing the Shinkos about once a year; I like the warm and fuzzy feeling of having fresh sticky buns more often; with the Avons I'd likely end up with a front tire four years old at some point.

                  This reasoning is how I also change rubber on my Goldwing
                  The Bridgestones I favor are the least expensive GOOD set of galoshes for the Wing -
                  They only last about 8500 to 9500 miles (which is what I average annually on the Wing)
                  So Each Spring I put on a NEW set and love a full season of riding on fresh tires

                    Based on Shinko's website I would say it is the opposite. The 712 is designed as a high mileage tire and the 230 as a higher performance tire. This is also suggested by the H speed rating on the 712 and the V rating that many of the 230 sizes carry. Your ADVrider thread is interesting, I have never seen anyone express discomfort with the 230's and I have no complaints with them myself, but I haven't tried the 712's for a direct comparison. I would say that either is a reasonable choice for our old bikes. I would use the 230's on my 1100E on a vintage track day with no concerns, but I am not a super fast track rider.

                    I also do this. I chose the 230's partly for their shorter life because I don't put a lot of miles on the 1100 and prefer to change tires more often for fresher tires at about the same overall cost per mile.
