Hello,

I just got new wheels (Konig 7.5x18) to replace my stock 8x18's.

Now I have slow leaks coming from all 4. Were they not mounted properly, or is it because I didn't purchase tpms rebuild kits?

They lose about 2-3psi a day.

Thanks for the feedback guys

 

I'm going to say not mounted properly ...but all 4?? Idk

 

If it makes a difference, these are the rims:

take to a discount tire if you got one. Theyll check it out for free an fix any leak for free.

 

The probability that you have 4 tires leaking at the same time is about 1000 to 1:

a. Installer used ill-fitting valve stems.
b. Tire size inappropriate and does not seat properly.

 

+1 yup what he said

 

The car is rejecting the crappy wheels. WHAT WERE YOU THINKING?

 

Its not tire size...you cant put a 16 or 18 tire on a 17 rim. 16 wont go on without shredding the thing completely. And then it wouldnt hold air at all. 18 would fit right over and you cant even get the bead to sit. Only thing would be half size tires aka like a 19.5 but those are usually trailer tires so thats all rule out....if its all four my money is on tpms.
-either valve core wasnt properly tightened
-the nut wasnt properly tightened or maybe over tightened and cracked the metal stem area
-the grommets are probably corroded and old and now wont seal
Get a bottle of spray, something that bubbles and spray it over your sensor. Just take it DT and get some rebuild kits. They are cheap and SHOULD be done EVERY time your taking a tire off and on. At least its what i recommend! I gave DT two years so trust me!

 

Wait so why did you downgrade ?

 

Why you downgrade?

Some wheels arent TPMS compatable. They might not have enough room to seat the whole thing in there comfortably without pressure on something.

Rebuild kits are inexpensive.

 

I would guess the rubber gaskets on the sensors. We sell the rebuild kits if you need them, just let me know.

 

I think what DavidV meant was the WIDTH being incorrect. AKA super stretched tires.

Regardless, I'm betting it's the TPMS as well.

 

Correct. We have members going with stupid stretch and fat tires. Extreme sizes may not seal properly.

 

if you really like the rims get the rebuild kit that tirerack is offering you. but check first to make sure the air leak isn't coming from anywhere else like the valvestems.

 

brb, putting a 195/60 on an 18x12 -34 TE37SL. Next up is 325/30 on a 15x7.

 

7 days and no followup. This is the new my350Z.com norm. Dead end gonnaget threads. Please help with no followup.

 

Only time I've seen this happen was on shitty rims with bad chrome and cheap no-name tires, they were all leaking around the beads. If you bought some made in indonesia tires with the DOT numbers cut out, then odds are you just need to buy some real rubber.

 

I've just been adding air every 3-4 days. Waiting for pay day so I can order some new tires, and with them I'll get the rebuild kits.

 

Or you could get the strap kits here:

That's how I had to mount the TPMS sensors on SSR wheels.
