I undercut on the M-12's in WA after a couple rides. It was the bees knees for those slipery snot filled root infested slow trails.

An undercut lug is going to have the same problem as a tractor tire put on backwards.

Looking at a tractor (or grader or earthmover or your choice) tire you may think, 'It would grab a whole lot better if it went the other way!'

Yep. It will grab until it packs..then the grabbing is over.

It's Maxxis Razors I think you put on 'either' way depending on the terrain. One way for sand (no packing there) the opposite for mud ('self cleaning' is the term).

Got a flat on the DR this summer, and you could stick your finger all the way through the hole, the rubber was soft as butter

My next tire chunked at 189 miles :evil:

I would be pleased if my tire had edge like that even if it chunked off a piece.

Hey carvr; the tire, undercut or not, would not pack up if you could spin the rear tire and clear it. My KX did it in spades. My KDX would if I just leaned the girl over a little. A spinning knobby will throw the mud off it.

I recall feeling my knobby load up when we rode GT on day two over on Darling Ridge. That was after the deep water crossing and up the gravel road. The loggers took out our trail and left a fine mess. You remember, right? Sure..... That's where you fell!!! Haw! I remember that!! So cool to watch the great Carvr lay that bike right over on it's side. HaWWWW!! SnorT!!

Ya know....
For just a minute there, you; me; and m0rie were sitting in a saloon watching a pretty girl pick a tune out on the juke box while swapping storys and lies about the day's ride.

(Damn) :partyman: :cry:

Cheers fellas!!

I'd rather be a smartass like carvr, than a dumbass like.... well, you fill in the blank!

It would be much easier to skip all that work with the cuttin' and just . . . reformat !

That exceedingly intelligent and respectful individual knows how to cut tires! He is my hero! Risking it all on a paved street with an un-licensed bike shows his conscious was thinking about the public good instead of his own while he probably wiped pornographic graffiti off the surface so our children wouldn't have to see it. He was brought up to work hard for every penny mowing lawns and doing manual labor but his hard work with lower than average wages meant nothing as he scrapes up his last penny to buy a new rear tire so he can erase some more naughty words from US-441. We need more like him. I wish I was.

I just re-read this opening to this thread. I didn't notice this crude insult at first but now that I have thought about it I have decided to be offended. Saving money doesn't make me the "cheap bastage" I thought I was at first. And what is a bastage?

I use an angle head grinder, takes about 10 - 15 minutes. I put the bike on a stand or crate keeping the tire off the ground and so that I can rotate it. It does create some smoke and thows little molten blobs of rubber so I set up a fan to blow the smoke outside and sweep up the rubber when i'm done. I've heard of other folks putting a cutting wheel on their grinder to do this. I didn't have one so I tried the standard grinding wheel. Worked good for me! :lol:
