High Speed Rear Blowouts

"The meek shall inherit the earth" I dont think that includes humans the way were going. Ants and turtles have been around for hundreds of millions of years, I think they know some thing we dont......all this started with a simple thought of the hare and the slow turtle, dont ask.

Bairdco started it by saying the slow get eatin.....

"There's always a bigger fish" seems to apply.

Qui-Gon Jin's most memorable quote from "Star Wars Episode One: The Phantom Menace."

so, uh, back on target here, there's some stuff called "rim cement" that's designed for tubular bike tires which might work. you could try it on the beads of your tires, maybe that'll help.

i wouldn't drill the rim out and put in a grommet. i think the air pressure, rider's stress, etc. might just blow it out. and it'd probably weaken your rim.

That's a good idea—though I'd only use a small amount, I'm sure it's a pain to get off.

Also—you might try replacing your rim tape.

Usually tires shift because they're under-inflated.

You may have also damaged the valve stem area while inflating your tire (when pulling the pump off). I've ripped entire (previously undamaged) valve stems off of tires (both new and old tubes). And I have spaghetti arms. It's a fragile area of the tube.

Inflate to 65lbs or even 70!! Use the PRESTA type tubes that have a thread locking valve system. You will need an adapter for inflating.Make sure the valve is staight up and down while inflating.

I use Serfas Drifter S tires. I think they are the best motored bike tire made. Inverse tread, 4 layers of flat protection. I ride at 40 mph for 10 miles just to get to town. I think you need to get rid of the weight inside the tires. A Drifter S tire is 40 bucks they come in 1.75 and 2.0 width. Try one with just a hvy duty tube. No slime tubes. No flat protection strips. Make sure the hole for the stem has no sharp edges. Inflate to about 40 lbs and look at the stem. If it isn't straight drop the pressure to about 5 lbs and work it round till it is straight then ride at 60 psi. Since I switched to these tires I have had zero tire problems. With the inverse tread they are very smooth rolling and vibration free. The S stands for survivor series. I have about 400 miles on them now and they are showing almost no wear but they still have great cornering traction. These are far and away the best bike tires I have ever rode on.

Junster - nice tires man!

I've been risisting the urge to get a nice set of streets for mine, what with winter just around the corner I figure no sooner than I ditch the knobbies - it'll snow...

I will admit I've been runnin' el'cheapos - just some random low cost tires I scored off a garbage bike. They must be fairly common because I've no less than three sets of exactly the same tread design - ALL off dead junkers! o_O (which is awesome given I really like the tread lol) No fancy liners, no sketchy goo tubes, just yer basic Walmart Bell tubes and inflated to 50psi.

I beat my ride mercilessly. Trails, highway use, even a mini "Death Race" tribute in an empty lot - I've never had a tire/tube shift on me or even a flat! Well, I did pop both the tubes the bike came with when it was new - but as they both "seam split" within 15 miles of each other I figure those were defective.

I wonder given what Junster and others have said - if perhaps alla fancy tire liners and whatnot are actually contributing to more problems than they're protecting against?

I was wondering how effective the liners are myself. The have them at Walmart now for $9 so maybe give them a try and see for myself.

I do know the thorn-proof tubes and goo made a big difference for me. Used to get a flat almost every long trip but now only once every couple years. Thorn-proof helps a lot with punctures but also the goo stops un-noticed slow leaks which is the "silent killer".

My first set of tires were Kenda 26x2.5 tires with heavy duty slime
tubes. This is running the GEBE 35CC four-stroke set up and I have lots
miles with these tires with no trouble. The only problem is at speeds above
25 mph, they make an annoying road sound on blacktop payment.
I have serfa drifter tires 26x2.0 on my China-Girl 2-stroke engine set up
with regular size slime tubes. I have been putting alot of miles on this bike
recently with no tire problems.
On my GEBE 40CC 2-stroke I have Serfa Drifter 26X2.0 tires and regular slime
tubes that I did not have any problems with until recently I added the tire liners.
There is about 14 pounds of engine set-up weight over the rear tire. I had only
about 27 miles on the tire liner milage before I had the blow out.
The Serfa Drifter tires are a really good choice to me based on my experiance
with the store model stock tire. I have the Maxxis HookWorm 26x2.5 tires with
regular slime tubes on another project bike and have not got to try these out
yet. I was really surprised as to how thin these tires are. But I have no opion
on them yet until I get to put some miles on them. I run all my tires on the same
brand triple-v wheel sets..
I am learning alot about tires from this thread.....thankyou
