maybe a bad batch,me i would try one more set and if it does it again dont go back go with what has worked in the past

The 3 sets of TRCs I tried didn't peel in the least. I did get one small chunk but that could have been from hitting something rather than the glue giving up.

Something also to confirm on the tire separation is what tire sauce were you using.

BSR had an issue with the glue on it's oval tires in the pink, dbl pink back a year or so. If you changed what you used, no issues and they have since changed the glue.

I've been running black/purple can Paragon. If the track is really slick I'll use sunscreen. I've never had a BSR tire tear/chunk (both 12th and 10th scale)

My observations on glues and chunks:

Many brands like Jaco and apparently the new TRC's have gone to CA. This makes for a very strong bond so no problems there but there is another issue. With the softer rubbers like yellow, pink, magenta, etc., the CA soaks into the foam a bit and makes it very brittle. The foam can actually tear right at the transition from foam with no CA in it and where the CA has soaked in. What you end up with is a torn edge but you still see foam on the wheel. This doesn't seem to be as much a problem with the harder rubbers like purple, black, lilac, etc.

Many other brands like CRC, BSR, etc. still use some sort of contact or rubber cement. When done right, I believe this is better as it does not make the foam brittle. The only problems is that if it isn't applied liberally enough, you can easily have a thin spot and if it is near the edge, it will chunk easily. If this happens, there will be little or no rubber left on the wheel. Also it can be weakened by some traction compounds.

So like everything else, it's a compromise.

With Tires especially Jaco's (Which is the only tires our store stocks) I always check each rim for any area's that pull up or are loose and repair them with Contact cement. Making sure to wait min 15 min after coat. if I need wiggle room a tiny bit of thinner to make it moveable and presto.

Now I also Like to get Donuts Either BRS or Others and cement them to the rims I like ( Old Skool BSR's) or hot bodies. With Contact Cement and they last a lot longer in the chunk department

Mind you no matter what you do to the tires hitting a sharp object like a railing or wall will take it's toll no mater what. especially at 45mph

Another thing to watch out for is breaking traction. When the car slides, then suddenly hooks-up again, it puts a tremendous strain on the sidewall of the tire. This can cause even the best glue joint to separate, or the foam to tear away from the glue.

I've seen many cases where a car looks decent overall, and is running fair lap times, but will sometimes break traction at the rear end, snap around the corner, then square up. That is incredibly rough on the outside rear tire, and I've seen instances of EVERY brand of tire peel/chunk under those circumstances.

I'm not sure what CRC uses to mount their foam...but when I tried to mount my own on CRC rims and dunked them in the lacquor thinner the rims softened so I doubt they are using some sort of contact cement.

I believe that T.M. Tires still uses contact cement as well and it seems to work great.

An odd thing that we have been seeing lately are how some tires actually separate from the middle of the rim as if there wasn't any glue underneath but the T.M.'s have been very good with not doing this. As for the chunking issues, it seems that this can happen to everyone's tire, and as others have already noted, especially with particular compounds.

All in all, everyone (CRC, T.M., Jaco/Parma, BSR, TRC, RC4 Less, etc.) is making a quality product but it is interesting how different traction compounds (JTG, Paragon, SF, etc.) and different racing surfaces seem to be affecting the glues that different manufacturers use for their tires.

The best thing I have found for diminishing chunking is to really round off the edges, especially on the rears; this seems to help with what Ian brought up about the "slide and grab" condition that can occur in normal club type bite.

The other thing I found that really helped me with chunking is to have a set of tires for each run. This way I do not run a set of tires without checking for separation of the foam from the rim. Before the next race day I will re-glue any tires that are lifting as part of the tire truing process.

hello everybody.

Is the Speed Passion speedo competitive on 10,5T 1S lipo (12th scale, sp V3 motor)? Does anyone has a setup he wants to share?

I've been looking around and there is a bunch of new softwares from SP and HW. Should i stick with sp softwares or the new adjustability of the HW's is worth giving it a try?

I will be racing this week end and i would love not to start too far away of something that works.

thanks in advance for the help.

JP.

BSR uses ca on the outside part of the rim. You probably noticed after soaking, the inner came off fairly easy but the outside was a little tougher to get off. This makes it less likely to roll/seperate the sidewall from the rim under high speed turns.

I know why my 1/12th tyres chunk

.... I am a crap driver and i kiss the boards too much

CRC new 65C battery released !

CRC not BSR
