Hello! I know this might sound silly but I got confused with some stuff I heard about this. My question is what is the correct PSI for the Maxima Tires, I have a set of BF Goodrich 195 65 R15, and I always try to keep them on 35 PSI, is that correct, this guy from work just told me I should never keep them under 40 PSI, checked the internet and found recommended PSI is 29, cant' find the recommended PSI on the Tire, it just says never inflate over 44 PSI, I don't get it, when the PSI reach 30 it seems that it needs air, so that's why I keep'em within 35 PSI, am I missing something here? Thanks in advance for your help.

 

I run anywhere between 32-38 psi on my tires...

Just don't run under or over the recommended tire pressure listed on the tire..

 

Nissan tire inflation specs are in the owners manual and also under the center armrest, lift up and look in the top piece.

 

I keep mine @ 36 psi

 

Tire Manufacturers don't put tire pressures on the tire anymore (except the max) because the proper tire pressure is specified by the car manufacturer. The Maxima pressure is on the inside of the center console lid and reads 29 psi. You can run higher or lower, but handling, braking and tire wear will be affected. If your tires are wearing evenly across the tread, you're at the proper pressure. If the tread wears more in the center the pressure's too high and if they wear more on the edges the pressure is too low. If your car is always heavily loaded, then higher pressures my be proper.

 

Ok guys, Thanks a lot! Then I guess I'm ok driving at 35 PSI, because if normal is 29 PSI I have my sound system in the trunk and usually travel with 2 passengers, My tires are 1 year old and they seem to be wearing evenly, or at least I don't notice a big difference on the treads.

 

Depending on the time of year you may want to adjust pressure to account for the tires heating. The heat comes from road friction, air convection, braking habits, and the tranny via the axle.

So if you run 40psi on a hot day they might be heated to an undesirably high pressure while driving. Personally, I go little over the spec and keep 32 up front and 30 in the rear. I've got Kumho ECSTA KH11 if it matters...

 

I am running mine at 40 psi but then again I have the japan version of the bridgestone pole position.

really?my 17's are a few years old (got em used/trade)and the fronts are 44 max pressure and the different 17's on the rear are 51 max pressure
ive been running 40 cold on all four am i dumb?

 

All tires manufacturers put the maximum (not maxima!) pressure on the sidewall. This the highest safe pressure you can go. The vehicle manufacturers sets a pressure which is optimum for that particular vehicle (with stock wheel and rim size)

High pressures will give you better mileage if it makes a difference.

 

40 psi in winter .......just because

 

If you drive for performance, keep your preasure higher than the recommended for the car and not higher than the tire maximum. This will ride a little firmer. If you drive for comfort keep your preasure closer to the recommendation for the maxima.

 

too high tire pressure will cause premature wear on the center of the tire tread.
too low will cause premature wear on the outside of the tire tread
factory sez run 29. I run 32.
