Road smarts

My Road smarts arrived today and I immediately noticed a different rubber compound between the front and rear tires. The fronts were made in Japan and the rears made in France. The front tire seems to be of a harder rubber. Another thing I noticed was a very stiff sidewall on both front and rear. They maybe the stiffest sidewall of any of the GT tires I have used so far. The BT020 and PR2's have very soft sidewalls and the smarts and Road attacks were very stiff. However the PR2's I have used turned out to be the incorrect tire for the GT. (No "B") Those are my observations so far, I have a question for you guys that mount your own tires. How much cussing am I going to do when mounting these Road smarts? Here is a good link for info about the Roadsmarts http://www.motorcycle.com/products/d...iew-75375.html

Quite a bit if it's cold outside and they are stiff.

I find of I cuss enough loudly, my neighbor hears me and asks "if I'm changing tires again?" He then offers a beer and comes over to shut me up at the request of his wife, fsr.

Oh. Get some Yamaha Tire Mounting Lube. Good stuff and it helps a lot.

All I can tell you is that the rear Roadsmarts are dual compound rubber with the harder compound in the center strip and the softer/grippier on the sides where it is needed. The front Roadsmart is only a single compound tire. Don't think the origin of the tire has too much to do with the quality of the tire? As far as the stiffness of the sidewall, I do know that a few manufacturers recommend a stiffer sidewall for this bike if available due to the bike's initial weight and use as a tourer when fully loaded and passenger on board.

I mounted my own RoadSmarts. No big deal.

As with any tire, make sure it is plenty warm before you try to take it on or off. In the winter time, set the tire over a heat vent in the house for a half day at least. Use plenty of lube. I use a 50/50 mix of water and dish soap, but others use Pledge, etc.

My front RoadSmart went 6400 miles. I have removed it and put a spare used tire back on until the rear RoadSmart wears out. The rear should probably last at least 9000 on my bike.

I also noticed that the front and rear were manufactured a world apart. Strange.

Thanks for the info gentlemen. I posted the origins of the tires because They are indeed a long way apart, And being so far apart I thought the content of the rubber would be very different. Kinda of like New york and Oklahoma pizza being different. I use the No Mar lube. Pretty good stuff. I think I will hit the neighbor up for help before I start cussing this time.

More thoughts about the RoadSmarts for anyone that cares...

As mentioned, only the rear is dual compound. I pushed the front to 6400 miles, but it started handling poorly at least a thousand before that. When I say "poorly", I mean that the front end got heavy and I had to strong-arm it in the curves. The curves are my favorite place to be, but not with a bike that doesn't want to turn. I replaced the front RoadSmart with a decent used BT020 and the bike handles fine again.

The smarts handled very fine up to that point. I had no complaints.

I would much prefer that the front and rear had a matched tread life. Even if they are within a thousand miles of each other, I'd still replace them as a set. In this case, the rear will outlast the front by at least 2500 miles, probably more. There's too much tread on the rear to take it off already.

I've already purchased a set of PR2's, which have dual compound front and rear. If they don't wear more consistently than the Dunlops, then I'll try something else next time. There are lot's of tires out there to try.

My buddy experienced the same with his Roadsmarts (FJR1300). He runs through 'em pretty quickly as well (Iron Butt rider), 30 days of vacation a year and no kids at home doesn't help keep the mils down!

I put 10k on mine but they were feeling heavy at that point. Front was just at the wear bars and the back look like it could go another 2-3k easy. Just put the second set on for the trip to the rally.
