Thank you very much for your advice. I checked the tire pressure and found that it was 36 psi for all four tires instead of the 33 recommended by the manual and 32 recommmended by you. The original pressure could have been even higher seven moths ago.I wonder why the Nissan dealership did not follow the instuction from its own manual.
Anyway I reduced the pressure to 33 psi and found that there is significant improvement on rough road surface. I am going to reduce the pressure to 32 to see if there is further improvement. But I cannot do it right away as the tire pressure has increased to 36 psi when the tires are still hot from the drive.
The Nissan dealerships should pay attention to details in their garage services. Besides the inaccurate tire pressure, they also forgot to tighten the cap of the coolent tank in my car during scheduled maintenance, which would lead to the engine become overheated when the hot coolent evaporates. The 2007 Nissan Sentra is a good quality car, the dealership should prevent mistakes that make people think the car is bad.

I agree with you.
When buying a car, the dealership should make sure that the car is delivered with the tires inflated to the recommended pressure.
Now, if you are going to travel in hot weather, with a full load and at sustained speeds of 70 mph or higher, by all means increase the tire pressure to at least 36 PSI.
The higher the pressure, the higher load the tire can carry (do not exceed maximum pressure as printed on the tire sidewall).

32 psi does give a smoother ride.
Thank you for the additional information.

Question about this: if the transmission's gears are replaced by a belt, is Nissan not engineering the transmission to be not as durable by designing something that will eventually break? Like the timing belt in every car except Toyota? I'm a little concerned and confused that they would create a new maintenance issue.

Its not a belt in that sense, as its made of a much stronger material. Not sure what exactly as its not just steel either. some kind of alloy I'd guess. so no, the belt breaking isn't an issue. At least not any sooner than any other transmisson would need rebuilt or replaced. If fact, thats what kept cvt's out of larger cars for so long. the engineers couldn't come up with a belt strong enough to withstand the torque and HP of larger more powerfull vehicles.

Excellent, thank you. You know the car makers made a serious mistake replacing the timing chain with a belt, and some, like Toyota, have gone back to the chain. If belt-driven transmissions were in our future, I would give up on automatics altogether!
Thanks for sharing what you know!

I found this webpage and according to waht they advertise you can get an aftermarket beeper for the locks in a 2007 Sentra 2.0. I have not ordered it yet, but I am seriously thinking about giving it a try. I also found the same beeper they sell ib Ebay for around $20.00.

On my previous Sentra, an '01 XE, I switched from the factory Dunlop's to Yokohama Avid Touring's and couldn't have been happier. The Dunlops were toast in 24k miles, the Yoko's had 50-60k when my wife totaled the car, and they were still in great shape. The Yoko's also came with an 80k mile tread life, but still would drive circles around the stock tires. When my '07 needs tires I hope to find something like that set of Yoko's to put on. They are recommended without reservation.
A previous post had someone stating that Bridgestone tires were made by Firestone. The opposite is true, Bridgestone is/was the parent company, and Firestone was one of it's major divisions.
As to the quality of Firestone tires, I worked in the auto industry as the time of the Firestone recall. The tires that were actually affected by the recall was not a huge number. Firestone did however recall ALL of the tires in that model. I had in fact owned a vehicle with those tires equipped the Radial ATX. They were good tires, and I wouldn't worry one bit about owning another set of Firestones again. They still make great tires.
The problem with that situation (the Explorer rollover problem) was partially Firestone, partially Ford, and a lot of the comsumer. Many people were buying SUV's for the first time and they were driving them like they were cars. You can't do that with a vehicle with that high of a center of gravity. To lower the C/G Ford engineering decided to lower the tire air pressure from 32 to 26 psi. This is adequate if the air pressures are maintained properly. Most people don't do this, and can easily on a tire that size be 5-10lbs low on air before they notice. That could potentially put the air pressure at 15-20psi which is way too low. This caused too much heat to be generated, and that leads to premature failure. Ford blamed Firestone, Firestone blamed Ford, but noone blamed the driver for not maintaining the air pressure. The bad PR was everywhere.

I'll keep looking but wonder if I'm in the right place for 07 SE-R aftermarket support news. Love it and looking to play with it.

My '07 Sentra 2.0 SL came with Bridgestone Turanza EL400 tires. I'm assuming this is what everyone else got also. A few thoughts on the tire: poor wear, loud road noise, sloppy in snow.
I'm considering a snow tire because I have to drive about 50 miles round trip to work everyday. Also, I'd like to make these tires last through next summer. I'm at 21,000 miles and not too pleased with wear so far.
