My write up may take a week or so to complete so keep an eye out for it by next week. Sorry for the delay but, I'm going on vacation Saturday and I'm planning on writing everything up then.

That's exactly the problem, to wide for the fork. I almost ran with it to. I saw a post by Ryan saying he needed a front tire and it has to be a 100 or smaller because it wont fit. I looked at mine and was thinking "what in heck is he talking about, mine fit?" and then it dawned on me that when the forks compress (they are inverted) the outer fork tubes will hit the tire! lol This bike has a lot of small things that will jump up and bite you if you dont pay attention (which I didnt). At least for me that americanmototire place is just down the road and I'm gonna bite the bullet and get some good tires this weekend. BT601's if they have them and TT91's for a second choice.

I have conventional forks so I have not run into that problem. Is it hitting on one side only or both? If its hitting on only one side you maybe able to cut down your spacer a bit on the opposite side to move the wheel over a bit. This might require using an extra washer or something on the caliper to offset it aswell..... just a thought.

I found another place that has 32 spoke 12mm ID bearings on 12 x 1.85 rims with rotors, so I might go with that since it will be a little wider, and hopefully give a better profile than the 12 x 1.60. Is that extra .15 worth $40? Because thats the difference between the 1.60 and the 1.85. Thoughts?

PitBoy: It hit both. I guess the pitster has a wider triple tree than the orion. The wheel and tire set I bought was made for a pitster/SDG.
cparty: I can tell you that I have a 2.15 rear and a 1.85 front and with the same tire mounted on both they look like 2 completely different tires because of how the profile has changed. Thats .30 difference though. But the difference is so huge between the two sizes I would think that .15 would make a obvious difference and probably be worth the extra $40. What wheel is it?

Linky:

eBay Motors: PIT/DIRT BIKE RIMS TIRES 50 70 110 125 10" 12" 14" XR50 (item 250142737864 end time Aug-12-07 0809 PDT)

It looks like its a 12" x 1.85 rim with 32 spokes and for a 12mm axel. Fingers crossed. I'd be running a 100/90 on this and a 120/80 on the stock rear.

Honestly it looks like the 12 x 1.85 he is advertising is a rear wheel. It's hard to tell because he has so much crap up there but I think thats what he means. I wouldnt do it cause it looks like youll just get a 14 front and a 12 rear and still be in the same boat , but it will float better because youll have less money in yo pockets

I think I just may have saved your azz! I stumbled across this: eBay Motors: 12" wheel 12in. rim with disk red rim. pitbike pit bike (item 150147888830 end time Aug-07-07 12:51:02 PDT) It looks like it an orion wheel. Its got the same disc rotor and a 12mm bearing. Lucky bastard

I sent him a message asking about getting fronts that were 12 x 1.85 and he said he can do it, so we will see what comes, because I ordered a front from his other auction before lunch. To the best of my knowledge there is no such thing as an Orion 12" front, because all the bikes I've seen come either as a 10" 10" set up or as a 14" 12" set up. The bigger bikes have even bigger wheels so thats obviously no help. That might be wrong, they might make a Coolster or something 12" thats identical, but who knows? Well either way, I took the plunge and ordered a wheel so let the fun begin. Now the other question who has TT91's in stock? 100/90 and a 120/80 please

Well I'm gonna bid on it then, I need another set So please guys dont out bid me

OK, so now for the next newb question. . . tubes or no tubes? I know about running tubes in my current dirt tires, but what do you do for tires that are designed to be tubeless? Do you just buy a valve stem, pop it in, spoon the tire on and inflate it? Will that work with my rims that are designed to be run with off-road tires and tubes? Or do it just use a tube in a tubeless tire? I understand how to do it, I just don't know what to do.

You have to run tubes with spoked wheels unless you have some trick way to seal the spoke nipples

I do have a couple of cool ideas, but I doubt they would work.

1. I got this fron a bicycle forum which is why I'm sure it won't work. Take a tube and cut it around the circumferance of the tube (like where it would touch the ground). Now you have a circular rubber strip, and can slide it onto the rim. Then mount the tire so the rubber strip gets sandwitched between the rim and the bead, fill with air, cut off excess. Thats a crappy 30 sec. description but it works for their small tires with lower pressures, which is why it most likely won't work for us.

2. The other idea is to take this silicone pipe sealer I have (its a 1" wide by 3' long strip of silicone that you can wrap around leaking pipes and they will stop leaking. Its flexable and sticks to itself, and worked great on a leaking pipe in my basement) and wrap it length wise around the inside of the rim where the spokes sit flush with the rim. Wrap it around 6 or 8 times, mount tire, fill with air. I doubt this would work because there is no way to gurantee it will seal out the air, and its made more for drips and leaks than 25 PSI.

So all that typing, and I will just buy 2 new tubes.

lol Yeah I've had the unfortunate pleasure of prying off 2 tires and it was no picnic! So I would assume that when putting them on, anything you have set up in thier on the rim will get all messed up and pushed around while trying to get that sucker on.

Can you run tubes in Tires that are meant to be tubeless? My guess would be that it would work fine. I picked up an Xtreme CR2, and ASSUMING IT HAS THE 12" x 2.15 RIMS, and that I am using it as a pit bike currently (not racing) I was planning on using the Kenda K761, 110/90-12, which are tubeless tires. Any opinions, or possibly a better tire to use for the pits?

Ryan NJ

Use the tubes.
