Topic: Tire seating woe's!!!!

[LoopsAndLogic]

ok, i was the one that screwed up my 400f's rim....
http://forums.sohc4.net/index.php?topic=52315.0

But were back in business with just a .5mm -1mm or vertical run-out at this point

New problem!!! I can't get the tire to seat in 2 spots.....

On the tire valve side and directly across from it....I've literally sprayed the crap out of it with soapy water...

Even when I put a bike tie-down around it to aid in seating the tire, it won't budge in those area's!!!

My tire is a 90/90-18, but the tube is a 3.25/3.50!!! Could this be hanging me up??

I have a 2.75 -3.00 Kenda tube on hand.

What else could I do if it's not the tubes fault??

P.S. Kenda Challenger tires suck!!! It already has cracks from 2 years of riding. And it was properly taken care of through the winters.

Just went through this problem on my 750F2 (Comstars). Tried different tires, tried different tubes, tried a different rim  - no joy, even with upwards of 60 PSI. I finally got it to seat after cleaning the wheel in the area where the tire bead sits (and the ramp leading up to it from the center well) with a scotch brite wheel mounted in an air powered die grinder. I followed up with a buffing wheel & rouge. I then quickly went over the bead of the tire (the part that seats on the rim) with my scotch brite wheel, and I applied a lubricant to both the rim & the tire bead. After all that it eased right out with about 20 PSI.

Sounds like you may have a steel rim with spokes. Clean up any & all rust on the inside of the rim as best you can - wire wheel, sand paper, steel wool, etc. Do the same on the tire bead.  I've had good luck with the waterless hand cleaners (like Goop, no pumice) for a tire lube.

Good Luck,

 What age is the tire, from the date code?

Those are all excellent points. Get the rim very clean. Soapy water isn't slick enough. DON'T USE ARMORALL. But goop, or commercial tire lube. But finally, if you haven't already, take the valve stem out, hit it with 150% of the tires max PSI, more if you cn stand it. Hold the wheel so the broadside is facing you, just a safety step.

A google search will pull up similar suggestions.

The rim is cleaner than my house

The Kenda tire is from 2004.... I'm heading out to the moto shop so I'll see what they have....

Thanks for the idea's, but is there anything else I could try??

I pumped the tire all the way up to 59 psi, and it still won't pop...
 does anyone think it might be the oversized tube??

Max psi on the tire is 45 because it's a front tire only.

Appreciate the fast reply and help
