Tire AIR LEAK

Recently purchased a 2015 Tacoma. Within about a week of purchasing my tire pressure light was on, checked and it was around 25 psi, brought it to the dealership they checked the tires no punctures or cracks in the tire. Filled it up and had no issues for almost a month. About a month later light was on again checked again around 25psi, filled it up and brought back to the dealership. Nothing whatsoever no punctures cracks, etc. SO they asked me to drive on it and see if went down again. Sure enough about a month later 25 psi again.... brought back to the dealership and they couldn't figure it out their solution have me buy a new tire and that will solve the issue. So I started looking for deals for a new tire. within about a week it was at 25 again. Any suggestions what could be leading to this leak that is gradually getting worse, and no one can find a solution.

Pisses me off that within a week of driving off the lot the tire was low and Toyota can't figure out why, could it be an issue with the tire itself mounted incorrecty or something?

 

Might be a crack or defect in the wheel, leaky valve stem, something small caught in the bead during install like a piece of the idiots shirt... If the same tire is still mounted to the same wheel you still have a list of culprits

 

I would try replacing the guts in the valve stem.

 

I'll be damn if Toyota would have me buying a new tire. They could shove that idea right up you know where. You had it documented it was happening. WTF?

 

Maybe take it to a different tire shop and possibly take the tire off and put it back on... That would suck to already buy 1 new tire.

 

Take it to a tire shop with a large dunk tank (preferrably one big enough to fit the whole tire at once, not one of the little half circle shaped ones), and have them dunk it to look for leaks. My guess is probably something's not sealing right with the TPMS valve stem or valve core. I would say possibly a slow bead leak but i doubt it on a brand new truck with new wheels and tires. Unless the bead was damaged while the tire was installed at the factory.

 

It would suck even more to buy a POS Dunflop. They should have handled this the first time. Second time they should have replaced the tire even if it was on a good faith offer. There should have never been a third time for the same problem on a new truck. Hell my dealer replaced all 4 of my wheels and front grill on good faith offer. That dealer needs to step up and satisfy a "NEW" customer. That's how you lose customers but, I guess a crappy $100 tire isn't worth a repeat customer anymore.

 

Try mixing dish soap with water in a spray bottle. Pump up the tire way over rec. pressure and spray it down looking for bubbles, also take off the valve stem cap and hit the fill area. Good luck if no success, bust that dealer!

 

how did they check it? the rim and tire have to be immersed in a large vat of water and held under with a large arm, if they don't have this setup, go to Discount tire, I just went through this and couldn't find the leak, several inspections by me couldn't find a nail, took about a week to lose 4 lbs...they found it in a flash, removed tire, patched it from inside, mounted and rebalanced, good to go....I use Discount/America's tire exclusively, have been for about 20 years, they know their stuff...

BTW, dealers can suck, you should have some kind of warranty if it is a 2015...at the very least they should work with you on a heavily discounted price if the tire needs replacing...

Honestly Have no idea how they checked the tire. The first time I brought it in they took it into their shop and I thought nothing of it sat in the waiting room and walked the lot. Second time I dropped it off before work and picked it up on my lunch break. The final time I brought it in I spent the whole time they were checking dealing with the service rep at the front desk while they checked the tire.

I have tried the water bottle method couldn't find anything with the naked eye tried the valve stem and outside side wall of the tire, as well as the tread. Not really set-up to get at the inside side wall of the tire without crawling under the truck (with my knees not the best option).

Probably headed up to a tire shop tonight after work. Issue is I can see if its a valve issue or something one would think should be covered under warranty (truck is like 3 months old), and I need to pay out of pocket to get it fixed. The dealership is not going to reimburse me.

 

Take the guts from the valve stem of something at home, bike, lawnmower, wife's car. Swap with leaky tire and see what happens.

 

I wouldn't be doing any of this on a 2015. Dealer can fix it, if they can't, they can replace it. #warranty

 

Valve stem is simple stuff, take like 30 seconds, much less hassle than f'n with the dealer.

 

Yeah but he bought a truck with a warranty. There is no reason he should have to be doing anything to it while it is under warranty. There shouldn't be any excuses for not covering it either.

 

I agree and wouldn't do anything more than a valve stem swap. I hate sitting around the dealership while some minimum wage jack hole f's with my truck. Only reason I go now is for free oil changes.

 

So a minimum wage jack hole is ok working on one of the most important things in an engine though?

 

Ha ha, good point. It's free and after that I will only go back for warranty or recall.

 

Shouldn't be buying any new tires or anything. It is a new truck, and you have a warranty. Tell them to fix it.

 

Completely agree but their solution is now I have to buy a new tire because they "can't" solve it. Its infuriating and with my truck being my daily driver, I can't keep bringing it in once a week for them to look at it and tell me nothing's wrong.

I hate to do it but I think the best solution is to take it to a tire shop have them look at it and then whatever I get charged take it to Toyota and give them the bill. They have the record of me bringing it in 3 times and not being able to do anything for me.

The dealership isn't that close to work so I have to take a curtesy car or taxi/bus to work and is only open weekdays for drop ins and weekends book up weeks in advance. SO for convince sake think the tire shop a couple blocks form work is my best bet.
