Come one, come all, gather round fot a post that is going to make you think "that was logical, why didn't I think of that all on my own?"
Foam inserts are how we simulate tire pressure. The more foam you stuff into a front tire, the more rigid the carcass will be. How rigid you want the tire depends on the type of surface you are on. Think of a full size car. For the street (high bite) you want to run the air pressure right at the highest the tire manufacture recommends. For sand (low bite) you air down so the contact patch increases which increases traction.
For the front of a 2wd buggy the right amount of foam can vary from the Losi 2wd front specific foam (about half a rear PL foam), all the way to a full rear open cell foam or a front closed cell foam. Less foam for a low bite track so the tire footprint increases. For high bite you want a lot of support so the tire is not deforming under load.
As far as whether to put the holes in the tires or rims. Rims always, tires too if you are running closed cell inserts.
Man you guys are lucky to have the internet. You guys would have been screwed back when you actually had to figure this stuff out based on logic and common sense.

That's all I have to say.

Buddy your a shit ass is all I have to say nobody needs a smart ass comment. They asked a question I've ask a few on here and got a smart ass comment from you. They wouldn't have been screwed that's what we had local hobby shops for to ask questions and get help.
That's all I have to say.

No offense intended personally but he's right. The basic concept should be within the grasp of anyone.
EDIT : I just realized who I backed up. My apologies to everyone.
Also there doesn't seem to be a dedicated tie/foam fitting thread. Here is the biggest thread I could find http://www.rctech.net/forum/electric...ub-racing.htmlI recall thinking months ago this is a subject deserving of it's own thread. Personally I am a tire and foam freak. Sometimes it takes 30 minutes and 8-10 combinations of foam/tire/wheel to get the feel you want. Sometimes it is perfect right out of the bag. Most of it is sitting and looking at the tire and just thinking. Then go wear some shit out and do it again.

Back in the 80's the racers at the track would help out and I used to read RCCA to see what the pros were up to. Never had an issue getting information. The forums are nice because you get a larger sample size of skill set and ideas tried by others. I dont see a point in being hard on new people.

The funny thing is he posted some very knowledgeable simple ways to apply inserts and the reason why to. Then insult them by saying they were screwed if it weren't for the internet. Thus saying they are stupid.

Sorry for the foul language guys it burns me up when somebody like him just runs over people asking for some simple help I love this hobby but no need to run the new people over that's how the hobby grows is helping the new guys and I want this hobby to be huge. I know I get tired of answering the same question myself but do it and give all the help I can.

Long story short. There's more than one elitist prick one here. Sure it can get old answering redundant questions over and over but if you can't, or don't want to, provide an educational and useful post without being a prick. Then don't post at all.

@R.Shackleford, Great information...wrong delivery. I only asked b/c I'm new to inside racing on clay. I only get about 3 hours a week to work on 2 chassis including any rebuilds or prep work because I work 60 hours a week and have a wife, 2 kids and responsibilities outside of the hobby. To waste the time and money to mount a set of tires up wrong is just dumb without seeking a reasonable method the will produce the results I am looking for. Again, I understand tires and inserts as I have been in the hobby long enough to remember Kyosho reusable 3 piece rims with no foam insert and the first car I drove was a Rough Rider with a stick radio. I just haven't raced a 2wd buggy in a long time and things have changed drastically in the hobby since I bailed out in 2005. So before you start saying that I would have been screwed before the internet you should realize that I started in this hobby as a 6 year old kid before there was an internet.
