Does anybody have this setup, and how much air should i put in. The place where i got them put on put 45 psi, and the ride was bumpy as a rock. Right now, i have 35 psi all around, but i would like more ideas. Thanks

 

Whatevered is recommended by the sticker on your door...and then play with it from there to adjust to your own needs.

Even though the volume increases, it doesn't mean to change the pressure...

 

41 is too much.
34 is just right.

I hope your rim size is 18x7 or 18x7.5
and NOT 18x8.

 

i read the max psi on the tires.. it said 50 psi. I found that out the hard way that 35 psi is too low... got some dings on the rims from small bumps on the road. They still look pimp though . I put 42 psi on the front and 40 on the backs...Any more ideas?

 

damn, where do you live? I wish i had roads like yours...

 

when I had that size 35 always looked like I had a flat.

38 to 40 didn't make a difference. My max PSI was 44.

If yours is 50-51...you should be ok with 42/40 PSI

 

first off you hvae the wrong tire size

 

what u mean? My rims are 18x7.5.

 

that he has the right rim/tire combo:

18x7...225, 235, 40's are ok. but hard ride for 225's.

18x7.5...235/40 preferred.

18x8...235, 245, 40's are ok.

 

...you should be ok with 42/40 PSI

 

Sorry buds, most of you are all wrong.

Max pressure on a tire indicates that it is the maximum allowable pressure the tire can safely handle. DO NOT inflate to this unless specified by the car's owners manual.

Your car company, in coordination with the tire industry, calculates a specfic cars PSI using that particlular car's weight and weight distribution as two major factors to deduce an optimal PSI for your Maxima to yeild optimal handling/comfort and tire longevity.

Deviating from the reccommended PSI for your car, no matter what size you have, will give you uneven wear over long periods of time.

Just because you upgrade tires to a larger size, does not mean to change the pressure.

Basically, you overinflate to save your rims, you wear out the middle of your tires faster.

You underinflate to give you mroe traction/comfort, you wear out the outer edges.

You keep it at around 30 psi front/back, your tires will wear out evenly.

well.. i'd rather cough up money earlier for new tires than coughing up money for new rims and tires later...

 

...who inflated their tires to MAXIMUM PSI?

...I didn't see anyone...

They said 34 PSI.
