Driving in third world country roads, over inflate tires?

PSI won't cut it.
Why not check out visa and work permit requirements for Europe?

 

Higher tire pressure makes for harsher rides, so the potholes will hurt even more.

 

Softer tyres reduce shock loads on the car and suspension but increase rolling resistance.

 

Horray! Another obsessive post by mwok.

 

The general rule of thumb when driving on roads with ruts and pot holes is that higher tire pressures will put the tires at greater risk but might help save the rims. Rims usually cost more than tires so I would use higher than the recommended pressures.

If it were me I would try 40 psi or so. The ride will be a little harsher than with the recommended pressures.

 

You're right, but also the higher tire pressure is going to slightly increase wear on the suspension components, so mwok's suspension is going to have a shorter lifespan

 

You need to inflate the front tires to 95 psi and rear tires to 93 psi. Otherwise, you risk a tie-rod end break, at which point the car will lose steering and go "in the weeds" or the electronic steering will command "full left," which will cause you to crash head on to a SUV, leaving 5 dead.

 

Are you kidding? Either that or you're being mischievous! There's no way I'd inflate my tyres to 95 psi, well not unless I want an imminent blow out or bounce 5 foot off the ground if I hit a bump.

 

I can't find it now, but there is a graph showing wear and tear on the Gen 3 based on PSI and it goes up hugely with PSI. However, there is a very tight range sweet spot at which MPG soars to 115 city and 97 highway and will let the car hit over a G on the skidpad. That must be what 32kcolors is referring to.

 

Just don't go all the way to 95.

The sweet spot is 94.5.

Hilarious story, good read. Some Prius owners belong to a radical wing of hypermilers (?sp.).

 

I hadn't seen that! I wonder if she was deliberately hypermiling or simply had no idea what she was doing.

 

My guess is that the male significant other in her life created those bombs for her to drive around on.

 

Don't anyone tell this to Wayne Gerdes's tires. It might give them ideas.

 

Take a pillow. Now take a ball that weighs the same and blow it up nice and high. Which one would you rather have hit your face at 50 mph? The more air in a tire, the less it compresses. The less it compresses--travels--the shorter the distance a given impact is dissipated. Shorter distance = higher acceleration forces. A ball made out of diamond would still compress, albeit it very little. It would be like a very high PSI object. How much impact would that absorb? It would make for a rough ride riding on diamonds instead of tires.

 

Sure, if you deflate your tires enough and hit a big enough pothole, the tires will "bottom out" and the rims will take the brunt - and they are much harder than tires. At recommended or near recommended inflation, you'd have to hit one hell of a pothole to bottom out. So much so that I'd be more worried about my car, perhaps my kidneys.

At the end of the day (assuming one utilizes common sense and keeps at least a reasonable minimum inflation), the rule of thumb is the more PSI the harder the tire and the rougher the ride. The rougher the ride, the harder it is going to be on you and your car's suspension.
