Default 3 piece forged rim seal leaking

Anyone had this problem and other than pulling them apart has anyone had success just by torquing the bolts to spec? ......whatever spec is for these rims.

Its a slow leak right now, but annoying.

Are you sure it’s from the seal?
Where they ever taken apart?
If you think just torqing the bolts and leaving out the seal is ok, the. Just sell them and buy a cast wheel lol

Yes, I’ve had them checked. It’s the rim.

I’m going to try resealing the seam inside the rim first, before pulling them apart. Quickest and cheapest route. 50/50 if it works, but it’s worth a shot.

I've rebuilt numerous sets of 3 piece wheels. I always use GE Iron Grip clear silicone adhesive. The best way to tackle a leak is to disassemble the wheel and clean all surfaces real good. Apply a small bead to each sealing surface and reassemble the wheel. Replace 4 of the bolts at 12,3,6 and 9 o'clock and hand tighten them to pull the 3 pieces back together. Once tight, use a clean rag and wipe any excess sillicone that squeezed out. Now replace all the rest of the bolts and torque them down in a cross/star pattern keeping track of which ones you have tightened by marking them with a tab of blue masking tape. Depending on the wheel manufacturer, 35-45 FT LBS. Once the wheel has been fully assembled take some masking tape and line both sides of the seam all the way around the inside of the wheel. Take the silicone and place a decent size bead all the way around the seam. Using a wet spoon, smooth out the silicone. Work fast enough as to not allow the silicone to begin setting. Once smoothed out and while the silicone is still wet, remove the tape. This will leave a super clean flat bead with nice clean edges. It should look like a 1/2" wide clear rubber band has been wrapped aroung the entire inside seam. Allow the silicone to set at least 48-72 hours before attempting to mount the tire. You can certainly try just the masking tape portion of this method to reseal the wheel, however, if you chose this part, make sure to remove the old sealant by cutting it away with a new razor blade and thoroughly clean the seam before any application of new silicone. Good luck!

Thanks Matt.

I had the tire pulled and cut out all the old glue in the seam and then took a wire wheel and went around to get any remaining residue out.

Tomorrow Ill clean it out good with alcohol and glue it.

It's possible that a slow leak in your tires could be caused by loose lug nuts or bolts on your wheels. If the lug nuts or bolts are not tightened to the proper torque specification, they may not be holding the wheel securely to the hub, which can allow air to escape from the tire.

One solution to this problem is to simply torque the lug nuts or bolts to the proper specification. The torque specification for the lug nuts or bolts is typically listed in the vehicle's owner's manual, Felgenversiegelung or you can find it by searching online for the make and model of your vehicle and the specific year and trim level.

To torque the lug nuts or bolts, you'll need a torque wrench. This is a special tool that allows you to apply a specific amount of torque to the lug nuts or bolts to ensure that they are tightened to the proper specification. You can rent or borrow one from a local auto parts store, or purchase one of your own.

It's important to note that you should always torque the lug nuts or bolts in the correct pattern and sequence, following the instructions for your vehicle. This will ensure that the wheel is properly seated and the pressure is evenly distributed.

If after torquing the lug nuts or bolts the problem persists, it could be the case that the wheel is bent or damaged, or that the rim or tire has a leak. In that case, you may need to take the wheel off and inspect it more closely, or take it to a professional to be checked.

It is important to regularly check the torque on the lug nuts or bolts, as they can work loose over time due to vibrations and changes in temperature, and if not properly tightened, it can compromise the safety of the vehicle and the performance of the tires.

You might want to relook at your concept of loose lug nuts causing tire pressure loss. Tires seal to rim and the rim attaches to the vehicle.

He's not referring to loose lug nuts. 3-piece wheels have hardware that bolts/secures the "pieces" of the wheel together (hence "3-piece wheel"). Those can come loose and, in turn, create issues with sealing.

exracer was responding to post#7. In post #7 junihoramos was suggesting that loose lug nuts were the cause of the tire leak and that is just plain wrong.

Post #4 is an excellent response to OPs problem.
