They (tire mousse) are very popular in cross-country rally racing, like Dakar. But they have the same problem as the tire balls, that is they melt when they get too hot. You have to keep your highway speed reasonable to keep the heat down. Could be an interesting option for a Ural, ha ha! I haven't seen them available for car tires though.
Friction between the tire balls or the mousse and the tire is a major reason for the failures. Lots of lube between the two goes a long way towards preventing meltdowns. However, extended high speeds on a highway is pretty much a death warrant with either of these systems.
Sheet metal screws through the side of the rim into the tire sidewall was common on desert racing bikes back in the early 70's. Years ago Sun rims used to come with little pins that you placed into holes on the inside of the rim at the bead that acted as an anti-spin system.
Yep that looks like the item. Not really sure why it never took hold with car tires could have been numerous reasons from financial to structural.
Here are some pictures of the bead lock type system I was talking about earlier for running low air pressures.
They can be put on both sides of the rim.
We use bead lock rims on the cars we race in Baja and the pre-runners used to practice (aka: pre-run) with. However, bead lock rims are not DOT approved for highway use and will have "Not for highway use" stamped on them.
Agreed. I mentioned them as they are a means to run lower air pressure and keep the tire on the rim. My case here is that low tire pressure to the extreme is not the best way to go on the roads most travel with the tires we typically speak of here.
Well damn the pusher Nitto SN2(center tire) seems to be out of round and wearing funny, if it continues at this I'll be back to the Conti Wintercontact (left tire)which is suppose to be harder and more all season orientated.DB
Anyone had anything to do with Yokohama Avid Envigor tires ? They are available in 175/65/15 and 145/65 and all season
My pusher car tire seems to have issues its a 175/65/15 Nitto SN2 winter tire,the center is going away on at least a third of the tire, like it was out of round or over inflated, it has been under inflated as I had a slow leak for a bit.It maybe has 3 k miles, I'm disappointed the Blizzak on the front is doing wonderfully.DB
I can't stop myself I ordered another Blizzak last night as I don't like questionable tires, when your used to buying tourances car tires seem like a deal.DB
The Nitto SN2 pusher is gone replaced by a WS70 Blizzak both 175/65's the Nitto didn't last 5k miles about 1/3 of the blocks just went away as though it had been over inflated and very out of round.I like the winter tires as I ride allot of places where and extra edge is cool, the Nitto had been cheap $70 free shipping maybe that is the problem.DB
On the Nitto the sipping in the center ridge and the white line blocks just went away and the rest of the tire was fine.
Dead an Dying Nitto
If anyone had a clue as to why this happened please tell me.
It's probably the swaybars fault ! Damn the Dude and full speed ahead.DB
Slight over inflation.
Play with the air pressure. Could be building up with heat if you are riding hard. Check cold and hot. Looks like you are running a Little harder into lefties and not right handers....lol. Swaybar? Yes unhook it and see what happens....but slow down ... just kidding.
Allot of this is like driving my old RX7 Mazda slower and smoother is faster, I've been going way to hard to the left and not hard enough in the rights.
Isn't that the wheel you had a hard time getting it to hold air? Did you get that fixed? It looks like overinflation on the center rib, but that wear on the right side maybe happened on one of your underinflated trips? Dunno. Also, mebbe you should get somebody to measure your leanout while you are sitting in the saddle and the rig all loaded up? I should do that too sometime.
I fixed that wheel awhile back and kept pres between 26-32 and nothing seemed to slow the tires erosion.I'm beginning to think Strokers right run what is suggests on the sidewall.DB
Even a blind sow finds an accorn once in awhile.It was a really out of round tire as soon as I left the driveway with the new Blizzak on the back I knew what was wrong with it.DB
Drone get a small torpedo level with a magnetic edge, attache it to your brake disk front or rear look at it if you have no help set the timer on the Lumix and set it on a milk crate and climb aboard.
I have slight lean in unloaded and and a pretty much straight bike loaded, lean left for right pull and right for left pull throw away your crown compensator and get a swaybar.DB
Blizzak much better braking on loose gravel roads, my bad tire must not have been very round, I noticed that as soon as I got underway with new tire, much smoother less vibration apparently Nitto was bad from the start.Onward and forward.DB
