WHOA!!!!
So after all of this tire pressure talk I decided to head outside to check the pressure in my tires...I've had my MZ5 now for about two months and am heading on a long road trip in a couple days so I thought it wouldn't hurt to up to par pressure wise...Afterall, I never checked the PSI settings since I drove it home from the dealership...
Both rear tires were set at 45PSI, while he front left tire was at 46PSI and the front right tire was at 48PSI!!! Jeebus man was the dealership trying to kill me and my family!!! Every tire was overinflated and these readings were taken with a digital gauge, and the car hasn't been driven since yesterday evening...
No wonder I was getting a bit of a drift at high speeds and wobbly cornering when at high speeds on the freeway...They're all set at 36PSI (which should be more than acceptable), and I'll be posting again with the handling and steering response now that they are where they should be...
***Edit***
Alrighty, I dropped the tires down to 36 psi each at cold temp. and the ride was way too gummy...The acceleration got notchy and hesitant, the steering was less responsive, and there was significant torque steer at accelerating from a dead stop and also when braking...I never experienced the grab when braking before so I had to attribute it to the new psi settings...Once the tires warmed up, I checked the pressure again and it rose to 37psi per tire...With thee ride still nowhere near where I wanted it, I added more air when they were still hot increasing the psi to an even 40psi per tire...
All problems seemed to be solved...Not only do I have a much more smoother and softer ride than I did before I began changing the settings, but the road noise has been cut down some, and braking & steering are responding perfectly again...In fact, the steering is a lot tighter now and there seems to be a good amount of traction...I road tested the new psi settings through the winding hillsides that aurround our house this evening and it took the corners like a pro...I am still experiencing slight torque grab when taking off from a stop when I give it a lot of gas, but thats to be expected in this type of car, and I've always had this...However, the grab when braking is completely gone now so thats a bonus
