Bleeder holes in your tires?
 

Just picked up some new proline MT's, and they suggest putting two air vent holes in the actual tires in addition to those in the rims. I have never done this before. I understand to vent the rims but tires? My instinct says "DONT". Any experience with this tire hole thing?
thx

I personally think you should leave them, i never read anything about holes in the actual tires themself? 2 holes in the rims should be fine.

I put about four holes with a needle in my proline mtr's it works fine. My rims have no holes in them. According to RPM if you put the holes in the tire and water or whatever works it way in centrifugal force will sling it out, if the hole is in the rim it will stay in there. It made sense to me.

exactly! grp tires come with holes in the tires.

For those with tire holes, how long do they last? I would think it would create a weak spot in the rubber and start tearing there...

If that is a problem, I wonder if some kind of metal eyelet would help reinforce the rubber?

i have put like 6 in each cf and got a whole season plus they are still half tread, it helps them respond to little bumps better, i use like a 1/32 dril bit worked great, although brushless may cause more balooning and possibly rip

I put two big holes in the rim (1/8" or bigger) and leave it

thats a good suggestion also, if you liike to wash your tires they will fling out extra water with the holes in the tire

Its no wories. I would get a set of leather punches and punch 2 holes in the tires. That should do. If the holes aren't perfectly round, I suppose its possible to rip the tire. With a punch that shouldn't be a problem. You would be surprised how much water will be slung out.

A lot of the pro's vent both the tire & rim. I prefer to cut a little slit instead of a hole. That way if you dont like it you can glue the tire back together.

I put slits in my tires and seal up the rims. This keep dirt and sand out of my tires. Since I have started doing it this way I havent had any trouble with my tires getting shaky or out of balance.

here's what RPM has to say about it:

...I think I like the slit idea better though...

I would use a needle. It seems better to me. The hole is small enough to be resealed with CA.

I just don't think the slit is a good idea because it is just asking to tear.

I'm going to do this on my next set of tires (don't want to do it on current G2R set because they aren't belted). However, I'm going to heat up a needle until its a good temperature, then use it to puncture holes in the tire. The hot temp should partially melt the tire and help keep the hole strong (no tearing).

that sounds like a good idea I might have to remeber that one! Thanks BP

It's amazing how much dirt can get into your wheels in a short amount of time. I was out in some sand one time and in less the five minutes I had about 2 tablespoons of sand in my tires. Dirt isn't quite as bad as sand but it can get in there pretty quickly too. I like this idea I'm going to start putting holes in my tire right away!
