nemo Posted March 4, 2013 Share Posted March 4, 2013 So I just drove my car for the first time in a few months (it's been sitting in a garage)... about 20 minutes in I start to hear a noise that I could have sworn was a flat tire. The car wasn't shaking... the noise was off an on depending on speed (around 40 and 70). There is no flat tire, though. Any ideas? If you don't vote Trump, out, you're a bigot who hates america.

nemo Posted March 5, 2013 Author Share Posted March 5, 2013 hmmmm... will it go away as the car drives? or do I need new tires? If you don't vote Trump, out, you're a bigot who hates america. Link to comment Share on other sites More sharing options...

Does it sound like it's coming from a particular spot? Fronts? Rears? Left? Right? Is it more pronounced when you hit a bump? Only at those speeds? -ben Link to comment Share on other sites More sharing options...
Fitz Posted March 5, 2013 Share Posted March 5, 2013 Answer is no flat spots don't normal go away, its why when u park a car its best to keep them off the ground or move it around now and then Link to comment Share on other sites More sharing options...

gt06unlimited Posted March 5, 2013 Share Posted March 5, 2013 you may have flattened a belt from letting the car sit. most flatspots from sitting will go away as the tires heat up. overinflate your tires to around 35-40 psi and drive on the highway. the pressure will rise another 1-2 psi as the tires warm up and if its due to sitting it will go away. you can trhen return to normal tire pressure. be ultra careful of potholes and bridge expansion joints at higher tire pressures though. your vibration could also be due to brake rotors. after sitting and going through temperature changes they can warp and vibrate. can you feel any pulsation in the brake pedal or see any shimmy in the steering wheel?

nemo Posted March 5, 2013 Author Share Posted March 5, 2013 Just filled the tires up at like 38 all around. Still there. I'm in Manhattan which makes it tough to cruise at higher speeds to warm them up but hopefully that will happen tomorrow morning. There is no vibration at all. Not in the steering wheel not while braking... If I was deaf I wouldn't think anything was wrong. It just seriously sounds like a flat with no other symptoms. But the sound is only there ar certain speeds. I've just got my fingers crossed that my wheel doesn't fall off or part of the suspension doesn't snap :o Sent from my EVO using Tapatalk 2 If you don't vote Trump, out, you're a bigot who hates america.

I Donated Too sigmafour Posted March 5, 2013 I Donated Too Share Posted March 5, 2013 38 sounds like a bit too much air... it's not a bicycle tire. what type/make are the tires? Link to comment Share on other sites More sharing options...

I Donated Too sigmafour Posted March 5, 2013 I Donated Too Share Posted March 5, 2013 I don't have much over 30psi in my tires. I personally think that's a bit too high but if you feel it's safe and working for you... http://www.spiveylaw.com/images/tireinflation.jpg Link to comment Share on other sites More sharing options...

I personally inflate to 38 psi just so that as I lose pressure due to normal alloy wheel leakage, I'm not too underinflated for too ling. Link to comment Share on other sites More sharing options...
nemo Posted March 5, 2013 Author Share Posted March 5, 2013 I'm well aware of what the specs are. Many people run 38/36 and it works fine for me. Drove the car this morning. It's definitely not getting better. Possibly getting worse. It seems to happen randomly from 20-70mph. Seems like the main speeds that it's consistent is ~35 and ~65. But again, there's no vibration or other shimmy. :nervous: If you don't vote Trump, out, you're a bigot who hates america. Link to comment Share on other sites More sharing options...

nemo Posted March 5, 2013 Author Share Posted March 5, 2013 Yeah, I'm just concerned because I've had the tires on for like 3 years with no issues. And the car has sat for the past 2 years (with me driving it every few months).... and this was actually the shortest time period of the car not being driven, and now this happens. The noise is just scary... literally sounds like something is going to fall off. I think I'll swing by a Subaru dealer just in case. Maybe have them put it up on the lift and see if anything falls out I'm sure they'll just blame it on being lowered/sways/etc It needs to warm up so I can put my summers on.

I have very stiff sidewalls on the tires I use but I didn't spot that - Just checked on the door and it says 35 front and 33 rear. I checked my tires and they were 32 all round. I stand corrected on the pressure Thank you Fultonhow. Link to comment Share on other sites More sharing options...

I dont think anythings gonna fall off. since you rarely get a chance to drive on the highway, its posssible that every time you drive the car and then let it sit again withuot the tires building up any heat, you create a new flatspot on each tire. before you pay the dealership to tell you its because of the sway bars and lowering, its worth swapping back to all season tires and saving some money. winter tires arnt really meant for dry pavement, so even if its cold out as long as the roads not covered in snow you can run your summer tires. but yes it really does need to warm up i want to roll with the windows down already!

I Donated thefultonhow Posted March 5, 2013 I Donated Share Posted March 5, 2013 even if its cold out as long as the roads not covered in snow you can run your summer tires. False. Summer tires lose traction very quickly below 45 degrees, even in the dry. Wouldn't hurt to put them on to test, but I'd take them off immediately afterwards.
