on a different note. My tire guy told me that they use some kind of sealant because this style of bead is known to leak. I've not driven much on these yet but one of mine is leaking - not sure where from yet (I know, I need to do my own homework there) but assuming it's the bead. Is this something you guys have experienced?

 

I hate to say it but 3 piece wheels are prone to leak a little. My brand new speedlines sat on a shelf for 6 months and had 12-20 pounds of pressure when I put them back on my car. They were set to factory pressures when I put them on the rack. The originals were flat after sitting 6 months and being set to 50PSI. Although those are 13 year old tires I use for winter storage. I always double check my Fikse's as well before going for a ride. Usually they are down a few pounds after sitting a month. BBS does a nice job of making the bead rough so it seats better but once rubber builds up most tire places won't take the time to clean any stuck on rubber which can cause a leak. Corrosion can be a factor on older wheels as well. My cup I's on my 928 leak after several months as well. It could be due to their PSD TPMS which has 2 holes and 2 sensors per wheel vs standard cup I's.

Did you try testing them in a large tub if water to see if you can see any bubbles?

BTW the sealant thing sounds like BS. Usually they only use a lube which is essentially vegetable oils and animal fats for the tire to slide over the rim. Not sure how you would apply a sealant if the idea is to make it slide vs grip.

 

I'll get out there this weekend with the soapy water to see where exactly it's coming from.

If it wasn't the person it is, I would say BS too - Sounds like something he knows to do when it's needed and something about these wheels made him feel ike he needed to. I'll ping him after I confirm where it's ccoming from. It's always possible the wheels halves are leaking.
I've had a couple other sets of 3 piece wheels over the years and have not had this issue yet. It was down to 10lbs after sitting a few weeks.

 

Never heard of sealant to prevent leaking from the bead. I would say there's a 50/50 chance that 3-piece wheels will leak, lol. I've also heard of lots of BBS wheels leaking.

 

I had one wheel leaking and a little bubble test showed a small leak on the tire to outside rim. Tire was remounted, leak gone.

good luck.

 

Happens all the time. Installers need to use extra lube on the e88 and higher psi to seat the bead or it will not seat all the way.

 

Sent you an email thanks

 

You got any of the E88s still available?

 

 

Good to hear it's a common mistake. what do you recommend on the initial higher psi?

Cheers,

Tom

 

Installer should Double up on the lube since the tire needs to go over the rough knurled bead seats and inflate to 95psi when seating the tire

 

thank you buddy! really appreciate the intel.

 

Took the fam out for a lil cruise around town.

 

What tire sizes are you running front and back? Very nice side wall.
