I bought my fm tc back in april 2006 and it currently has 4500 miles in it. My front left tire (Stock Bridgestone Potenza) keeps deflating (thanks to my tire warning light telling me) and it usually takes a week and a half / 2 weeks for my tire pumped at 45-48 psi (51 psi max) to deflate to 28-30 psi.

Do I call my dealership? Or do I call Scion? How about Bridgestone? Not really sure. Any suggestion will do.

Thanks In Advance,
Carl

 

i doubt anyone will warrenty the tire unless it is proven to be defective. have you had the tire checked by a shop? maybe it is just a small nail or a beed leak, both generally fixable for 10 bucks!

 

45psi???
are you nuts

should have 32psi all the way around

probably have a valve stem leak or the seal around the rim/tire isn't correct

 

Yeah, 45psi is WAY too much. I believe its ~30 PSI all the way around on a cold tire.

 

manual states 32 front 29 rear

is it ok to do 32 all around? any advantage?

 

Over deflated tires will cause them to wear unevenly. They will wear more in the middle than on the outer tread.

Underdeflated will wear unevenly also. They will wear more on the outside and less on the inside. Underdeflated tires will make you get slightly lower MPG too.

 

Could be defective tire, tire valve, tire valve cap, bead seat, wheel, or damage to any of those. Need to find out which part has the problem THEN fix the problem.

If it is a defective tire, the warranty is by the tire manufacturer, not Scion.

 

you have a slow leak. go to a shop and get a replacement, better yet, do yourself a good favor and buy new tires, the potenzas are ____.

 

lol warranty for a tire leak which most likely is some nail he doesnt know is in his tire. do some regular maintenance for once instead of complaining to manufacturers

 

holy crap!!! i have the EXACT same problem-same tire and all...though i dont take it 2 40 psi--only like 35... ive just been 2 lazy 2 take it 2 a shop cuz the leak is so slow.. but yeh a shop will fix it 4 like 10 bucks
good luck with ur tire

 

it's a leak! get it fixed at a tire store...i got mine fixed at les skawb (i can never learn how to spell that damn name).

 

Why would you put 45 psi in your tire? Sounds like you got a nail or something in there. Just go get it fixed nobody will warranty a flat tire. With that many miles and being so over inflated you probably need tires anyways.

 

^ Just get 4 new tires...the stock potenzas are crap!

 

hmm I am running Yokohamas, I guess some people get the Bridgestones and some the Yokos?
