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

 

are you kidding???

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 **** in the ear.
