PSA: Check your tire pressures

Does overinflation cause longer stopping distances? My car says to inflate to 38 psi. I once inflated to 43 psi to see if it would increase the range, and it did. I have had to do a panic stop before when the tires were at 38 psi, and the stopping power impressed me. After I overinflated the tires to 43 psi, I had to do another panic stop for a pedestrian who ran out in front of my car. The car felt like it was dragging itself. The abs was making a bunch of noise, and it felt like I couldn't stop as well as I should have. I missed him by a little less than a car length. Both instances were in similar weather. I realize there could have been oil on the road, or something, but I since dropped the psi back to 38, and it never happened again.

It's a well known fact that under inflated tires have more grip, so yes over inflating will longer the braking distance.

Yeah, I had previously driven a manual for about 2 years, then drove an auto for 3 and 1/2 years, needed to relearn shifting techniques.

I'm back to full proficiency, I just was unsure how sports cars are supposed to react compared to 'normal' and didn't think to check the pressure. 1st gear threw me for a loop under preasure, but I'm now shifting better than ever, having to learn and compensate for the excessive bumpiness. On the proper pressure it feels too damn stable, doesn't feel twitchy and powerful.

my tires say maximum psi is 51. 46 seems to be the sweet spot? under 35 and the tires look flat and steering is heavy.

forgot to actually ask the question, what psi should i run on my tires. my back 2 are on 36psi cause i have 2 different tires on the back and thats the max for the right side. and both the fronts are running 46 on same tires.

Most old people don't have a lot of disposable income. Maybe she couldn't afford new tires?

Coulda just helped her.

Does your car the have ranges written somewhere? Some manuals or instructions on the inside of the driver door will give you values for various performance characteristics, like load bearing, economy, comfort etc.
If not, figure out the minimum and work between the ranges to decide on what you would prefer.

What car?

the dude who owned it before me put on bigger aftermarket wheels with canadian tires. im running 205/45/17 fronts and 215/45/17 rear on 195/205. The oem wheels on my teggy is 195/55/15

205/40/17 and 215/40/17 not 45
