I know alot of tires say recommended psi 35 but wouldnt my car ride better with a little less air maybe 30psi?

Question

i have an 03 altima 215 55 r 17 tires what pressure would you run in tires that recommend 35 psi i put 35psi in but the ride sure seems rough.

these arent the stock tires the car came with 205/65/16 the door sticker for that particular size is 32 /
id like to put these tires at 30 not the 35 that on the sidewall, maybe even 28 is that dangerous at all

Answer 1

I also have an Altima SE with 17' tires the tires say 35 psi and the sticker says 32 psi . I keep my front tires at 30 and my back ones at 28 and it helps smooth out the ride tremendously. You shoudnt put the max air in tires , yes it may help handling but makes for one bumpy ride.

Answer 2

First off, it's not a good idea to deviate from the tire pressure recommended by the manufacturer. Having said that, one thing you need to realize is most new radial tires say "Inflate to 35 PSI," but your owner's manual or door sticker may say something different. In American cars, there is a sticker on the inside of the driver's side door (near the door latch) that lists the recommended tire pressure for your car. Check that or the owner's manual and adjust your tire pressure if you need to.

Also, when they give a reading for your tire pressure, that's when the tires are measured COLD (READ: You haven't driven the car for at least three hours), so the best thing to do is measure the tire pressure on a Saturday or Sunday morning before you take your car out to get the most accurate pressure reading.

If your car rides rough, it probably isn't your tires. You may need a front-end or four-wheel alignment. Most tire shops and minor repair shops like Pep Boys can do that for you.

Driving a car on underinflated tires is not good for the car. The car has to work harder to get up to speed, the tires don't grip the road properly, and they will wear out faster.

Here's a general rule of thumb. A lower psi will result is a softer ride but if you go too soft, you will have poor steering response. Also a lower psi will result in a little more tire wear (and less even wear too).

A higher psi (within the recommendations) gives much better steering response, mileage and tire wear. The downside is a rougher ride.

Does your car have driver adjustable suspension settings? If so try adjusting that before lowering your tire pressure.

Answer 4

You should never inflate a tire to what it says on the tire, that is just the maximum inflation rating of the tire. The manufacturer recomends a specific inflation for every vehicle and it should be located on a sticker inside one of the front doors, also in the owners manual. Most passenger cars range from 28-32 psi.

Answer 5

I read an article about nitrogen in the tires and how durable it is, with better ride and improved steering.

We had it put in both of our cars the mileage has improved somewhat also.

When I first read about this it made me nervous. But the article said that Jets use nitrogen in their tires, so how bad can it be. So we did it. They put green caps on the stems when it is done. I'm amazed how much better the steering and ride are.

It costs about $16.00 for a standard car.

Answer 6

that tire dont have much of a side wall,its going to ride rough...if you dont have the right amount of air in a tire and run high speed.the tire will get hot and may fail..be sure to set the pressure when tire is cold,you may come down a pound or two//

Answer 7

Cutting the psi to 30 will cause the tirers to ware faster.

Answer 8

if ur psi is 35 than and its feels rough when u drive, try lowering to 32 psi...

Answer 9

you will get better gas mileage with them properly inflated
