Alright Pred Peeps,
Newbie question; got any tips on 'truing' yer offroad tyres prior to gluing? I know it's not such an issue as touring car rubber, but I'm sure there's some performance to be gained by making sure those schumacher mini spikes are running nice and straight..

thats funny - I replied to this thread the other day....must have pressed cancel instead of post, or whatever the buttons say! this is what I do with my tyres.... buy them and then take them out of the packet well in advance of gluing them on the rims. This gives them chance to regain their shape after being crushed and pressed out of shape in the post. I leave them out of the packet for at least a day. Before i glue them onto the rims, I cut a small amount of the beading inside the tyre to ensure they fit snugly onto the rims, effectivly narrowing the bead of the tyre. Because I use pro-line inserts, which are quite wide, I trim the top edge off the insert, as recommended in the pro-line mounting instructions. then I put the insert in the tyre, and fit them to the wheel. I spend a long time ensuring that the insert is evenly and squarely fitted inside the tyre and on the rim. You can see any lumps or bumps in the tyre simply by rolling it along your workbench. If there are lumps or bumps, I move the insert/tyre as necessary to remove the bump, even removing and re-shaping the insert if necessary. When I am satisifed the tyre and insert are "true" I glue them on the rim. I use Team Orion tyre glue all around the inside of the rim to ensure the tyre is firmly glued to the wheel. Then, when the glue has dried, I run a bead of glue around the rim/tye to seal the tyre onto the rim. I also put one or two holes on the inside edge of the wheel, as per recommendations on the packaging of associated rims. So apart from that, I don't do any preparation of tyres at all, just slap 'em on the wheels! Hope this helps (and makes sense)

I make a hole in the tire and not in the rim as my theory is:
dirt will be forced out and not forced in. if you get what I'm trying to say....
Oh chris, next GP you may glue my tires ;D

Coops, you are soo kind - I look forward to gluing up your tyres after I have driven for 12 hours and drinking a couple of cans of whatever alcoholic beveridge we have got our hands on! ;D
I wouldn't make the holes in the tyre, as it is more likely
a) The tyre can rip b) the insert can get wet c) debris is more likely to get into the tyre
if you make the hole in the middle of the wheel, it is going to be covered more by the wishbone/hub reducing the chance of debris getting into the wheel and eliminating the possibility of the tyre ripping because of the hole.

I don't know what size of hole you've got in mind but they are not soooo big.... 3mm or so. If they are nice and round they will not make your tire rip.
and It's pure phisics. Imagine yourself as sand, and your are inside a very fast turning rim, you will be pressed against it and you will be forced into the hole. If you are on the outside you will *ptjioooooooow* catapulted away and not even get a chance to get into the tire.
now read the story again and replace the word 'sand' with 'water' ;D

Coop, your holes are not big enough, you need BIG holes.

couldn't agree more g.
The holes that i put in the wheels are probablyaround the 7mm diameter mark.....
I agree with your physics coops, but in reality it just doesn't seem to work in that fashion.
The best place for a hole is in the wheel, not only can you make 'em bigger, but if you go too big, you can make 'em smaller too.

I dont do it myself, but I have seen some people who put two elastic bands (one around each edge of the tyre) on the tyre once it is on the wheel, to hold the tyre in place, then apply glue. Might be worth a try!
