When I bought my car, it worked fine, no rattles, squeeks, ticks, nothin! One thing I always did notice is how the car always seemed to be slow or resisting acceleration, as well as cruising at 75 on the freeway, I'd let off the gas and get on the clutch and it almost felt like I was lightly on the breaks. I decided to check the tire pressures, and the tires weren't cold, but not hot. To my amazment all my tires were between 23 and 25 psi! So they were more like 20 to 23 cold! I filled them all to 35 and it felt like I did a performance mod to the car! I accelerated faster, cruised easier, and coasted forever! Has anyone else had an experience like this before?

oh and a side question, have you guys had better result from a dyno jet, or mustang dyno?

 

I had the same problem with tire pressure, but I checked tire pressure, oil and coolent levels and made sure my lug nuts were plenty tight before I actually left the dealer.

I drove a 99 Sunfire before the 06 SS 2.4.. and every time somebody else touched my car for repair / general maintenence, I always checked all of the above.

A guy I know (well, a guy I know through the gf) took his parents car into get an oil change at Canadian Tire, for some reason they took the front tires off thinking it was getting the front brakes done, then someone actually read the papers and realized it was just an oil change, and put the tires back on, but they didn't tighten the lugs enough when they put the tires back on... Front left tire fell off the car while driving home. He and Canadian Tire were lucky he didn't slam into anything.

 

holy ****! How is canadian tire still in business!?!?

 

That is actually a common trick that dealers like to do. By lowering the tire pressure, the tires get a "soft" feeling to them. This soft feeling makes the car feel less bouncy when you hit bumps in the road. Most people want a smooth riding car, so by doing this, the dealer is giving the illusion that the car has a smoother ride than it really does.

When I test drove my Redline I stopped at the first gas station we came to and put the correct pressure in the tires. The dealer looked at me really funny when I did it too.

 

I can tell you a story about lug nuts coming loose from every single place that does tires.

But I find it hard to believe that particular story because licenced techs don't do oil changes at Canadian Tire because an oil change pays .3 shop units and takes a half hour to do properly. Neither the tech or the shop can make money that way. So tire busters do oil changes and no tire buster is licenced to touch brakes.

 

You may be right, but he has a police report that states, pretty much what I just said.

 

not following you.. this sounds like you want to be a dynoqueen and not gauge true performance.. Dynoqueen numbers are Dynojets.. real numbers are mustang dynos

 

I used to work at a dealer and I have never heard of one doing that. It would suprise me if this were true.

 

Well i just want a reading of my power, TRUE performance is measured at the track. Bragging numbers are on dynos, so the bigger the better, if say my car is making 230 hp, but a dyno jet says 240, well it doesn't effect my cars performance, but does give it a higher number on the dyno sheet. Whatever I'm getting dynoed for free and the place has a mustang dyno.

 

Typically it's the opposite. Cars usually have their pressures inflated for trips on the car carrier and such so they dont risk injuring their new rims. This was very much the case at the Infiniti dealer i worked at. One of the steps in prepping new cars on the lot was to bring the pressures of the tires down. (were usually around 55-60 from the factory).

 

I agree- total bullshit!!
WOT

 

Maybe it's different from state to state or even dealer to dealer, but ever since I moved to Virginia Beach, every car I've bought with the exception of one (My RL) has come from the same dealer chain and has had low pressure in the tires. My Redline came from a different dealer but still had low pressure.

This could be a coincidence I suppose, but I think it's a little unlikely.

 

You may have just had low tires either from the car sitting on the lot for long periods, or a poor PDI- but implying that it's some sort of common dealer trick as you stated above is mere conjecture and total BS IMO
Wop

 

After the Firestone\ Ford fiasco, I seriously doubt it is done with intent. Like WOP said it is probably due to sitting for extended periods of time.

 

Yeah thats what I was leaning towards.
