split rim seal?

hay all.

ok bought all my bits today to refurb my wheels.

When i took a bolt out the split rim to show a nut and bolt place the size i need i noticed like a black substance between the rim and the wheel.

My wheels dont pysicaly come in half so i wont loose tire pressure just the centre and be unbolted from the rim itself.

Does anyone know what it is? its kinda like tiger seal... is it really needed?

And does anyone know were to get rim bolts from like these:

Rather than use 8mm allen key bolts as they look rather bulky.

I fount this aswell. Can anyone explain a lil better abouy what hes using here?

i will ask my guy but am pretty sure its just a weather seal - ie bath type style all weather one..

now the key is not too apply to much and make sure you nip all the bolts opposites to keep it evenly spread out..

also make sure you let it then dry before filling with air and then hear for leaks the next day..

should be ok if you follow that procedure

Its a product called Sikaflex

Thats the original and best but 15quid a tube. Can be got off ebay

Cheaper than i thought at 8 quid

That's very cheap for this stuff. It's excellent. I wouldn't recommend regular (as in the cheap crap B&Q sell) bathroom sealers as they peel easily from metal.

I'd go with this Sikaflex, or Dow Corning 'All weather mate'

As said, apply a small but consistent bead around the edge, then tighten slowly.

Or pay a professional (but seriously, it's a PITA when you re-assemble a wheel with new bolts etc only to find it's leaking )

I'd seriously consider buying all new bolts for these too.

could i buy this Sikaflex from local shops do you think?

i dont think my rim actually comes apart... so no need to worry about leaking tires etc..

could i buy this Sikaflex from local shops do you think?

Yeah, but it's around £15 a tube off the shelf.

i dont mind paying that lil bit more... were do you think i could buy it form, plumbers?

Some people use sikaflex, I used High Modulus Silicone Sealant from B&Q (under direction from Ibrar)

sorry to hi-jack this thread. could i use this sikaflex to seal my headlights up?? just thought while we are on the subject of sealant

If your wheel has the centre that unbolts and leaves the rims as one piece then you dont need any sealer.

If it splits the rims apart then you need sealer and will be the same as doing a 3 piece.

If it needs sealing then you do it in the tyre well not on the faces of the rim.

Same as i did with my 3 piece in the picture, this is before they were sealed, the 3 pieces join where the arrow is and this is where you put the sealer.

...If it needs sealing then you do it in the tyre well not on the faces of the rim...

Exactly what CCW say. They don't put the silicone on the mating surfaces.

I was refering to the picture the op posted in post 1 where someone is putting a bead of silicon on the face of the rim, meaning the outer face.

The video is pretty much doing what i did and seals the wheel well where the tyre sits. Good video

...does anyone know were to get rim bolts from?...

Not cheap, though, when you consider how many bolts there are on a set of wheels.

Pertsch have an online shop

Thats where i got my new nuts and bolts from, absolutey 1st class service and would recomend them 100%

looks like sikaflex to me too, will never pull the rims apart again with that stuff lol

I used Sikaflex but was Black, you remove all the bolts bar 4 but loosen them enough to get a thin sharp blade down the faces and then ease them apart, i did have a wheel balancing machine to hold them on though which does help.

The 4 bolts stop it all falling apart.

Speak to Ibrar at Speedwells if anyone wants info, weve rebuilt my 19" 3 piece 3 times now with no dramas, other than me changing my mind and going all Black instead of shiny bling
