Tire Problems
My tires got separation from the steel belting (I think this is what you call it) theres two bumps in it one on the inside one on the outside tread areas.
When you drive 50+ starts to worry me, 20-30 is fine but the car pulls right a tad and bumps up and down alil. So like my dad wants to get a new tire since I mainly drive him and he still owns the car, I can almost pay for another but not yet. Will a different tire in the back make much of a difference for a months use? I'll try to match the treads of course. Also what do you guys keep your tires pumped at? The current ones say like 20-45 I have em at 40 in the front 30 in the back (because of the bad tire) its kinda really bumpy but feels alot better then 30 in the front, i was thinking of 40 in the back too once we get the new tire in. |
If you have a different size tire in the rear your diff will spin at different speeds. This is not recommended.
|
by different tire do you mean size or type??
and how old is that tire? |
The tires are like 2-3 years old? Not sure, they still got decent tread, after driving on 5 it started to get bumpy then the rear right formed two lumps :(
I'm getting the same size tire of course, trying to match treads too to keep it similar but will it still cause a large difference? |
well if you get them the same size, but a little bit different tread it wont be that different, you probably wont feel it at all actually.
and those bumps are mostly likely from hitting something with the tire. but i suggest you replace it before the tire blows. |
I've not been driving long, once i entered a parking lot to turn back to my friends house like normal, i hit a inch of water apparently in the drive way
|
I would recommend getting two new tires in the rear. You can get some decent tires for like $60 a piece. I run my tires at 34psi with 215/45's all around.
|
Doesn't your car scrape? The front end and mufflers always hit the ground with 50's :(
|
If the tire is the same size (originally) it shouldn't be an issue. I got a flat in one of my rears about 10k miles into their life (about 1/2 tread depth loss) and replaced the flat with a new tire. 10k later, all is well and good, even though the newer tire still has a good bit more depth than the old one.
|
fix it before it blows out at the wrong time.
www.tirerack.com has some decent deals man. If you can't get all 4 then get a PAIR at a time. |
i think you should get a new set of rear tires just to be safe
|
^ this has been said a millions times already.
|
i think you should get 2 rear tires to be safe.
|
im thinking that its best for you to get 2 new rear tires just to be secure.
|
dood that's been said already^^
|
lmao.
|
In my opinion you should replace both rear tires just in case.
|
im feeling deja vu
|
yeah, just get another tire in that same size with similar tread patterns and you'll be fine. The tread pattern probably doesn't even matter either.
oh, and I think you should get 2 new rear tires just to be safe ;) |
Well, just like everyone else said, your best bet will be to get two new tires in the rear. you should also consider the age of the tires, if the tires are about 2 - 3 years old, check for and cracking/dry rotting of the rubber. dry rotted rubber can sometimes be the cause of a bubble in a tire. Bubbles can also be caused by some type of hard impact, letting the tire sit with too low air pressure for a long time, or can be a manufacturers defect. But if your tires are dry roting you should consider replacing them all.
I had a set of tires that had dry rotted and decided to blow out on me in the middle of a left hand turn. I lost control and ended up spinning out and hit the curb on one side of the street, and then spun the the other side of the street... I had to replace both rear lower control arms, 3 rims, and i had to buy a new set of tires... |
i think you should replace all tires

No wonder you have bulges if you are putting 40 psi in a street driven tire... I suspect that the tires are worn out as well. Then toss in the lack of grip because the tire is not conforming to road imperfections and you're probably are tossing the car all over the place. The recommended tire pressure is in the owners manual and on the tire size sticker in the car. For extended high speed runs (above 85) then add 4 lbs to the recommended pressure. There is no need ( and only reduced performance) by putting too high pressure on a street driven vehicle. The only time you would consider 40 psi or even above 34 psi, you better be on a race track and then only after testing for tire temp and sidewall roll. I am thinking that you don't need new tires, but a couple of auto shop courses. |
Would pictures of the tire help?
They don't look that pretty but I don't know. |
bulges are bulges man. No pics will change that. Don't be stubborn, listen, and replace them before you have a blow out in the middle of a turn.
|
I'm thinking you need two new tires in the rear, or a cock in the ear.
|
WHAT CAN YOU TELL THIS GUY??????:confused: hmm...............2 tires? Im a mechanic everyday to pay bills. If I see lumps in tires??? You could have a blow out. Or gimme money to fix it? When is your state inspection due? IDK LOL GRRR What to do? :wallbash:

but yeah the tires gonna go anyday and its raining now so were getting a new one :):) NO I didn't mean a pic of the buldges, you can hardly see them unless you go eye level to the tire, I ment of the side of the tire where you can see the rubber, it does look like its pretty old but I haven't a clue thus I was asking if I should take a picture, you guys could leme know if the rest of the tires are close to gone too 1 new tire for sure, most likely two, 4 isnt possible at all. :icon_no2: Also why is 40psi too high, I love the way it feels (No these arnt stock tires) they say like 30-50 on them or something similar so if its at 40 why is that bad? Its not exceeding the cold air pressure that their rated for. |
No maan, 40 is too much for the street. I only ran 40PSI autocrossing. Don't look at the max. #'s on the tire sidewall. Look at the sticker in your door jamb or owner's manual. Add 2 psi for a bit more feel or up to four for high speed driving. Measure tire pressures before driving for the day (tires cold). Start with 35psi on all four, then go from there.
Also, in case it hasn't been mentioned, get two rear tires. j.k. Did you buy the tires yet? |
so your getting 2 new rear tires?

Fill a balloon with as much air as you can. then sit it on the floor and try and balance a med sized dictionary on it. What happens??? The book rolls off, it won't balance. Why? Because the balloon can not level around enough to support the book. In fact the contact patch of the balloon is pretty small. Now fill a 2nd balloon with 3/4 full of air. Lay the dictionary on it. Look the book lies on the balloon and the balloon levels with a lot of contact to the ground. So, too much air, and the balloon only touches the ground in the very middle. Just right amount of air the balloon touches a lot of ground. Your tire works the same way. Too much air and it only touches in the middle (this shows as wear only in the middle of the tread) and you have a smaller contact patch with the ground (resulting in reduced grip). And then you will also get the tire wearing unevenly, with the middle of the tire's tread wearing out faster than the sides, as the middle section is bowed out due to too much air. Like this: http://www.procarcare.com/images/sha...ia/8852oc1.gif Now too little air and the tire wears on both the side walls. This is equally bad as then the middle section of the tread actually bows up, and you only grip in the sides of the tread. It wears looking like this: http://www.procarcare.com/images/sha...ia/8852oc2.gif and finally from tire rack on over inflation:

Advantages of Correct Tire Inflation
Maintaining correct tire inflation pressure helps optimize tire performance and fuel economy. Correct tire inflation pressure allows drivers to experience tire comfort, durability and performance designed to match the needs of their vehicles. Tire deflection (the tread and sidewall flexing where the tread comes into contact with the road) will remain as originally designed and excessive sidewall flexing and tread squirm will be avoided. Heat buildup will be managed and rolling resistance will be appropriate. Proper tire inflation pressure also stabilizes the tire's structure, blending the tire's responsiveness, traction and handling. Disadvantages of Overinflation An overinflated tire is stiff and unyielding and the size of its footprint in contact with the road is reduced. If a vehicle's tires are overinflated by 6 psi, they could be damaged more easily when encountering potholes or debris in the road, as well as experience irregular tread wear. Higher inflated tires cannot isolate road irregularities as well causing the vehicle to ride harsher and transmit more noise into its interior. However, higher inflation pressures reduce rolling resistance slightly and typically provide a slight improvement in steering response and cornering stability. This is why participants who use street tires in autocrosses, track events and road races run higher than normal inflation pressures. |
Well put

just replace them, end of story......problem fixed

You should never put just one tire on the drive wheels.
Unless your new tire is within a certain amount of wear to the old one (usually 1/32 to 2/32) you run a very serious risk of causing drive line chatter or differential damage. Your diff will think that one side of the car is going slower than the other side and try to correct the issue. Same problem with doing one front tire on a Civic or some other FWD vehicle. If a new tire has 11/32 and your old tires are worn down to 5/32, your asking for trouble. If you can't afford two new rear tires you shouldn't drive the car until you can. |
