Jarvis Bike Setup:
So the Shinko 216 front in 90/100 in only 1.5mm wider than an M59, both tires mounted, Tubliss @ 10 PSI. Perhaps the height, in addition to providing more compliance as noted, has other effects on the feel noted by some as well, like a wider footprint when weighted?
These are 4 ply correct? If so, like the F546, Tubliss dismount will be a bitch as there is no room left between the thick bead and liner.
I believe these may be 2 ply
Was it easy to mount, or stiff to get the last bead section over? The 546 was noticeably tougher than an average 2ply tire. Should say on the tire sidewall somewhere.
no drama at all!
Sounds like a 2ply then, there has been some misinformation floating around. That also means its lighter, the 4ply F546 was heavy and stiff. Maybe the weight/gyro effect is what some notice. I'll try a 90/90 next.
just another update on this tire. I have since sold the Beta and I'm on a Husky TX300 for now. I moved the fatty over to that bike and 30hrs later she is done. all of the side knobs are peeling off, but I don't think it's the tires fault. My tubliss system has been leaking down a fair bit on the front tire and I didn't check it before the last ride, when I got home and noticed the condition of the tire I measured the pressure and it was around 4psi. I don't know why the front is giving me crap, the rear tubliss with the dunlop d803 is right at 10psi every time I check it. perhaps the shinko is leaking through the carcass? I might have to resort to slime on this one. I've been using dielectric silcone grease with no slime for a tubliss lubricant with good luck till now.
Actually that sounds normal for a Tubliss front. M59s do that with some time on them. I think the carcass starts to break down and VERY small leaks form. Funny because mine will drop to 4 PSI the week after a ride and stay there, not go totally flat, so that tells me its happening as its ridden and flexes. I have had no issues just airing up in the AM for a few more rides until I change them.
Fronts can be a bit more fussy at times because there is more seal surface area, less room to move and conform to the bead, and more stress and distortion on the tire bead when mounting. If your mounting a front tire that's a known PIA, use Quadboss sealant as a lube/sealing aid instead of the grease. It won't react with raw aluminum like Slime will.
I did the "reset" with the front tire and it's now holding air just fine. basically, all I did for the reset was let all of the outer chamber air out and refill....weird, but seemed to work. Now I'm going to play with some different pressures to see what I like best. Still running without the damper right now.
