LGB Traction Tyres

I am about to fit a new traction tyre to a Stainz, my previous attempt some while ago did not go well, with the loco "throwing" the tyre a number of times, to a point where I am unsure what remedied the issue. As you know the new tyre come flat, i.e. as a disk rather than a tyre, so my question to the LGB specialist out there is:

The inside of the new tyre, does it go to the inside of the wheel with the tyre folded towards the outside of the wheel, or does the inside of the tyre go to the outside of the wheel with the tyre folded to the inside of the wheel?

Supplementary question:

Is there any specific "other action" that needs to take place to ensure the tyre remains fitted.

I look forward in anticipation to your replies, and many thanks :)
 
I fit with the inner of the traction-tyre, to the outer of the groove..

i also spend a little time, working my way round the tyre, with the flat of a screwdriver.. Just to ease the tyre to be about the same stretch all the way round..

(I have had some replacement tyres, where the was a marked 'bump' where the tyre had been joined.. These caused lumpy running, and I eventually dumped them for new ones).

PhilP.
 
I have given up on replacing them, I find that my Wizzy Cranks has run just fine without them for the last 2 years, though I can understand the a Stainz may be challenged in the pulling stakes without them.
 
Hi Jimmy B,

I have run my Stainz locos without traction tyres for a number of years without any problems. All the locos have additional lead weights to bring them up to 2.2Kg, which I have found from trial and error to be the optimum weight. One other benefit from not fitting traction tyres is improved current collection.

If it's meant to have traction tyres then fit them, the last thing you want is grooved wheels running round collecting crud, damaging themselves and the rail head :-) There are enough pickup points on even the Stainz that the slight loss of contact of the tyred wheel shouldn't make any difference, and remember the flanges will still pick up.

I don't think it matters which way you fit the tyres, just make sure they are properly bedded in as PhilP says.
 
I have had a batch of traction tyres that had "gone off". They had lost their elasticity and snapped when applied and after some time. I have also replaced them with brass strip with some success on a couple of engines - cut to fit the groove and soldered in place. I prefer this as it is better to have wheel slip than too much grip and buggered gears!

Hm it only takes a slightly wobbly bit of track or crud to reduce the traction tyred side to either the other wheel or the wiper, not the best or recipes for satisfactory running at modest Stainz type speeds. Though I think Jimmie’s 01480 212986 has had a battery conversion?
 
So many thanks for the responses, I have a newer Stainz which is battery powered with a new tyre fitted, the one I wish to change the tyre one is the older "clamshell" currently track powered, and has nothing like the pulling power of the battery one, mainly due to wheel slip, even with some added weight (now 1.8kg). It will be getting converted to battery (sometime) so pick-up is not an issue, however with a number of 1:25 (ish) gradients it need the traction.
It would seem that it does not matter, as long as it is properly bedded in, I will let you know. :) :) :)
 
I would never run a tireless rim as it can cause extra wheel wear due to different size wheels. Train track rails are not flat, they are rounded.
If a traction tire is falling off then the wrong size tire was used!! The LGB small tires fit real tight on the rims.
 
So having problems fitting the tyre to the Stainz, I have to stretch it over wheel, but refuses to sit flat. Yesterday and today I have tried but it refuses to sit evenly on the rim, and when I run it onthe rolling road, get a "bubble" behind the rim, beginning to think it may be a tyre issue, though I am wary of "a poor workman blames his tools" though spares in this case!!
 
Jimmy,
They may well be 'new, old stock'? - Especially if they are in pukka LGB packaging.. :wondering:

See my final comment in Post#2. - You may be better getting some new ones with Massoth branding? :nerd:
 
JimmyB - Greetings from across the pond! I concur with prior comments, don't run LGB locos without the traction tires........can cause wear damage to the loco's traction wheel and track rails. Similar to PhilP's technique, I use a miniature-bladed box knief, and putting the blade under the front part of the tire, I move the blade completely around the mounted tire to ensure it's evenly seated. For unmounted motor blocks, I use two clamping tools to install traction tires.......see photo.

Sounds like you have some defect tires which do get brittle with long self-life. I use both the LGB and Massoth traction tires which work well.

Update, no new tyres seem to be available. Last week I re-fitted the tyre, inner edge to the wheel outside, pushed it in place, but refused to stay fitted every time it was tested on the rolling road. Re-fitted and left, theory being it may gain some "memory". Today out on the track fitted as above the wheel through the tyre within a few yards as slow speed. After fitting a number of times no improvement, so it was then fitted with the inner edge to to the inside of the wheel and pushed in place and run, and it stayed in place. The tyre had been fitted this way around previously without any luck.
Moral of the story, there isn't one!!

Jimmy - I just fitted the 37.5mm traction tire onto an LGB Stainz that I'm installing a DCC sound into for a customer. I usually install a tire with the inner loop on the outside like I did in the photo below. Actually it should stay on either way. Are you using a 37.5mm tire? The larger 45mm tire used for LGB Mogul etc will probably come off a Stainz traction wheel. Tom

Do not worry, though if you are really concerned perhaps a spare set of wheels that do not need traction tyres might be in order judging by the views of irrepairable damage, damnation and all sorts of other horrors running sans traction tyres!

Hm I wonder if Snot would work for you, there is a product called that amusingly that comes in a tub that works for traction tyres. From US I think if anyone stateside can comment on how good it is.

EDIT FOUND IT.
Bullfrog Snot, link to it though there may BeUK suppliers if you hunt.

I have some that had lost their elasticity too. With nothing to lose I dropped one in a cup of boiling water for a few seconds... I's elasticity returned and allowed it the be fitted. When it cooled back down, (on the wheel.) it seemed a little harder than a fresh one, but had seated perfectly. That was about a year ago and still no problem with it.
Try it, what have you got to lose?

Paul.
