Actually I find dropping the pressure is worse for ride quality. Increasing pressure adds a bit more cushion. IMO

Your wheels are also exposed to more abuse.

This is true. The factory rim size is 19" and we don't have other trim choices in our place. The cost of a single tire is equivalent for a set of tires for our CR-V 98.

I was told that 18" and 20" tires are much cheaper and way easier to look for in stores. They said that 19" tires are somewhat rare. At least, here in our region this is true.

Going back to tire pressure, the door sticker indicates two pressure settings. One is for a fully loaded car and the other is when driving alone.

I decided to be in-between, the fully loaded pressure setting is too harsh for me while the other setting is too soft when a friend is with me from time to time. Since I lose tire pressure for a about 1 psi in a month or so (I believe this is normal, please correct me on this), I won't be below the recommended pressure by the time I check my tires and use my tire inflator.

If I may add, having a tire inflator saved me a lot of trouble back then. I got a punctured tire and I observed the harshness of the ride. I checked my tires and found out one of them is deflated. I used my tire inflator until I reached a vulcanizing shop.

One more thing, the gasoline station is quite far from us. If I were to drive there and have my tires filled up, my tires are already warm. I've read that the pressures indicated on the door sticker are cold tire pressures.

The two main items that change tire pressure are temperature and time.
Tires generally lose 1psi per month
Temperature changes are mirrored by tire pressure in a 10*F-1psi ratio; temperature gets 20* warmer and tires go up 2psi. If the temperature goes down 40* tires should drop 4psi.


On my car the door jam recommends 32psi cold.I check my tires when hot and have them set at 34F and 32R.
Them fancy tires TickerGuy runs only cost $52 a pop when you have an '03 6i with base 16" rims

Yeah, and the 17" rim version isn't much more. There's plenty to like in a tire that does ok even on snow, is reasonably quiet, has great dry traction and runs 50k miles for about $75..... It doesn't matter much if you only put 10k miles on the car in a year, as they'll deteriorate before they wear out. When you do 30-40k miles in a year.....

I drive around very carefully. I'm not about slamming those Michelins into pot holes and dragging them over railroad tracks. They're the sweetest tires...


Dropped the pressure down to 31 back and 32 front. Did some highway and city driving last night and the ride was much more comfortable. Big difference.

What tire are we talking about?
