All of my 'small' 1/8 and 1/10 trucks have what I suppose you can call 'breather' holes in the wheels, to expulse air upon sudden compression - basically big air and a heavy landing, to limit bounciness.
This works well, but can often permit the ingress of water into the same void, which can be difficult to eliminate.

I've noticed that ALL FG wheels, certainly MT wheels DO NOT have holes.
Who drills theirs, who doesn't, and thoughts please?
Many thanks,
Alan.
 
Best idea is to glue the tires the best you can. If you find that you were real good at doing it, then you will need to drill a hole in your rims. Very small hole. Mine are glues real well but there is enough pressure pushing on the tire from the foams to keep them flatted.
Most people run foams. If you don't, and you don't have a hole, they will suck in and stay sucked in a bit. Water is your enemy no matter which way you do it. :(

I would say do it only if you have too.:)
 
I heard this mentioned in a thread a while back & Im sure the advise was to put a couple of holes in to expel water & help the wheels balance out....might be wrong :blush: Even though my tyres are glued on I still get water in em so might put a couple of 1/8" holes in for the balancing reason. This should help the life of the wheel bearings as well.
 
Depending on your tires, I would be scared you will tear them out with holes drilled in them. I would keep the holes in the rims but that will not allow water to come out.:no:
 
Methinks I've invested a lot of money to start drilling holes too soon.
I used Pro-Line medium CA (15-20 second), which permitted me to quickly +/- fill the bead, then push the tyre in completely on one side (at a time ...) without problem.
I'm pushing half of my 82kg weight on it and there's no hint of a blow - good seal on the 2 tyres I've received so far - still waiting on 2 more from MMR Largescale (waiting on KCR).
Voo mentioned he'd drill as well.
I'm not sure about drilling the tyre either - I'm sure it worked for you or you wouldn't mention it.
The damping's on the heavy side which should compensate any bounciness to some degree.
Many thanks for the thoughts and ideas guys. I'll give it a few blasts and see how it is before I start drilling.

Spoke to Ian from MMR Largescale today - very helpful chappie!!
He believes that there should be a hole in the rim, which would also avoid 'popping' the glued tyre off the rim, should it come to that.
Another idea he came up with is a slightly oversize hole, and grommet / plug / bung which could be placed in the event there's a lot of rain - avoid ingress.

Al,I know they are very expensive wheels and I wouldnt put you on a bum steer but I think you will have to drill a small hole if the tyres are seated that good.Take it out ,give it a good ragging and see what you think, you'll find it not very responsive to steering input and when you hit a few bumps its going to be very unstable.I done the same with my MT and ended up drilling two 1/16 hole in each rim to 'cure' the problem.
Good luck

I believe making holes also helps for the ballooning effect. In an MT I wouldn't think there would be too much ballooning.

Interesting dilemma!!
Mine are most definitely round, and now well sealed.
I fitted the inserts, then tyres, then 'bounced' the wheel around the living room (so to speak), then rolled it, ... during 2-3 days, to ensure all is aligned as best possible, THEN I glued the wheels.
 
Holes in the rim allow the tire to breath yes but dirt and water goes in. then with centrifugal force of the tire spinning the water and crap goes to the outside of the rim and chews away at the foam, causing it to disintegrate long before the rubber does...

a few evenlt spaced holes in the outside of the tire, between treads, will allow the crap to escape when the wheels are turning, prolonging the foams life and keeping the tires more balanced
