Ok another thing. I have no clue as to what to run my tire pressure at. I run it at 40 right now. I can't figure out what the side of the tire is telling me.

Im going to go get my son Ill read the stuff and bring it in.
ok good some info to work with

even if the tires look good the belts inside can go bad, it happened to me with a tire than only had 5,000 miles on it, also a wheel weight could have been lost causing the tire to be out of balance

you want run your tires at 32 cold PSI, and i believe that it is 40 hot psi.....the info is on your drivers door sticker

Did you re-torque your lug nuts after driving a couple miles?

dont run your tire pressure at what the sidewall says, that is the MAXIMUM you can run them at, not the actual pressure spec. Always go by what the door tag says. And I think 40 psi may be just a tad high. My tires say 35 max, and my door tag says go at 30 cold psi, now my car rides smoother than ever. Also, my car had a bit of bounce...mainly because the stupid technicians at Fleet Farm who put my tires on, balanced the tires with a big dry puddle of brake fluid in the wheel. (my rear brake cylinders leak and the fluid accumulated when the car sat for 7 years. and then the tires were rotated) So when I recently had my wheels off so that i could change my struts, i scraped out all the dried brake fluid and mud out and washed the insides clean. They were then out of balance. I was still running at my max tire pressure then so when I took the car out on the freeway, it felt like i was driving on 2 basketballs. But when someone told me about how i should only run by door tag specs, i did that and the balance problem went away. Now don't get me wrong, i am still going to have them re-balanced but for now, it seems to work. Ok...what was my point again? Oh yeah thats right, 40 is too much! hah, check da specs on the tag and watch the wobble stop...but then again maybe it won't, just a suggestion.

About those rotors...it is my understanding that one should always replace things in pairs on cars, trucks and SUVs. one old turned rotor and one new rotor...umm does not sound like a good idea in my book. But that is just me. Good luck with your problems!

The average person should run their tires at what the door says. If you understand the principles and reasoning behind pressures and the effects.

With that said...James.. no need to confession brokism....we've all been there at one time or another. Limp it along and swap the other side when you can afford it.

You are aware that things aren't 100% and need to drive accordingly..that'* all.
