Vent holes in 1/8 Buggy wheels?
I've been out of RC for several years and even when I previously raced it was oval but, I'm going off-roading this time. I'm mounting a set of PL Recoils on AKA wheels and AKA red foams. I remember buying wheels in the past that had holes in them and people punching holes in their tires to allow them to vent. I see these new AKA wheels have tap marks for vent holes but, no holes. Is allowing the tire to breath a thing of the past or should I drill away?

depends on your track surface. That's why there are dimples... gives you the option.

If you run on a loose or dusty track don't drill the wheels, but do ventilate the tires.

If you race indoors on damp clay with no dust, do either- or both.

It's better do vent the tires and the rims. The dirt will come out the tires if you make a hole in them because of the rotating mass.
A hole in the rim lets dirt inside the tire, but there's no way for the dirt to exit.

at first i put hole in wheels and the dirt build up bad in the tires to make them not usable. started puting two holes in the center of the tire oppisate ends. since no problems. no holes in wheels.

With the new closed cell foams nowadays its almost useless to vent the rim. I have really not found anything in my rims after runs and reuse them all the time but we run alot of hard pack clay or blue groove here. I would vent the tire.

Yep, two holes opposite each other in the tires. No need to do the wheels.

Agreed, just the tyre
I reckon a small hole is enough - I do about 3mm, but I see some people do like double that (1/4" or bigger) and don't see why, the air gets in and out a little hole just fine

I'm racing on a hard packed indoor track so i just did the wheels. I think I'll try no holes next time since I am running indoor with little dust. Thanks

i always put holes in the tires, 2 on opposite sides, usually not in the middle and switch sides when on opposite side of tire. i always cover up the holes in wheels if there is one because its a good way for dirt to get in there due to centripetal force. with the holes in tires it lets water and dirt to fly out instead of staying in the tire. i know they must have a hole or they will swell and become hard.

I agree the tires are the best place for holes because of the whole dirt escaping phobia, but honestly I like to drill one really small hole in the rim so the air escapes slower than usual and helps the tire from slamming hard on the ground and going flat. It softens the landing....Just my opinion though, never had an issue with dirt buildup in the tire...and I race on dirt...

Okay, just mounted another set and decided to do tires only this time. I'll see which seems to build up the fastest or if they build up at all. Thanks everyone.

I use a leather punch to put two holes 180deg. from each other on the tire. I do this no matter what surface I run on. I do it mainly for when I clean tires. That way if I get the foam wet, when the tires are mounted they will expel any excess moisture.
