    • caught a segment on some car show about modding up your car. One of the things they mentioned was the benefit of filling your tires with nitrogen instead of air. Considering I fill my tires with air and don't have much of a problem constantly refilling them, what is the straight dope on nitrogen in car tires?
      — Dave from Massachusetts
      Oh, there are plenty of benefits: (1) Cool fluorescent green valve stem caps (assuming your nitrogen vendor has any marketing savvy), which will look sharp with your spinning wheel covers. (2) Bragging rights. OK, you were behind the curve with cell phones, iPods, thong underwear, etc. Nitrogen in tires is relatively new to the mass market. Now's your chance. (3) Reduced fire danger next time you land your space shuttle or commercial aircraft, and tell me you won't sleep better knowing that.
      Most tires are filled with compressed air, which when dry consists of about 78 percent nitrogen, 21 percent oxygen, and 1 percent other gases by volume. Water vapor (humidity) can make up as much as 5 percent of the volume of air under worst-case conditions. Filling your tires with nitrogen mainly does two things: it eliminates moisture, and it replaces skinny oxygen molecules with fat nitrogen molecules, reducing the rate at which compressed gas diffuses through porous tire walls. That means, theoretically at least, that a tire filled with nitrogen retains optimal pressure longer, leading to more uniform tire wear and better gas mileage. The commonly quoted figure is that tires inflated to 32 psi get 3 percent better mileage than at 24 psi.
      Does nitrogen make any practical difference? You couldn't prove it by me. I found no scientific tests showing that nitrogen-filled tires stayed inflated longer than average under normal conditions. A car-buff buddy was sure it worked but conceded he had only anecdotal evidence that it did.
      As for moisture, changes in humidity affect tire performance two ways. First, the density of humid air fluctuates more with temperature than that of dry air, so removing humidity can keep your tire pressure more consistent, especially when the temperature climbs over 100 degrees Fahrenheit. That may be a legitimate concern in Formula One racing, but it's not much of an issue if you're just tooling around town.
      Humidity can also be a factor in wheel maintenance - since pure nitrogen doesn't have moisture in it, supposedly your wheels won't rust as quickly, which could lead to improved wheel performance and air sealing. The question is, how big a problem is wheel rust these days? According to a few tire and wheel shops we contacted, not very. Seriously rusted wheels are uncommon in typical steel-wheeled cars, and many high-performance cars have alloy wheels that don't rust at all. One exception is work vehicles such as dump trucks, which are exposed to a much harsher environment.
      Another claim I've seen is that since nitrogen is slightly lighter than air, you'll save weight and get better performance. However, we're talking about a weight difference of less than 4 percent of the gas in the tire - in other words, a difference of less than an ounce for most vehicles. A possibly more realistic benefit is that nitrogen is largely inert chemically at low (i.e., normal) temperatures, so it won't attack the rubber in your tires like oxygen does. Oxygen attack is something both the National Highway Traffic Safety Administration and Ford Research have studied, and can be a problem for tires used for a long time or in rough conditions.
      More important, nitrogen doesn't support combustion, which is one reason aircraft and the space shuttle use nitrogen in their tires. The wisdom of this precaution was brought home by the crash of Mexicana Airlines flight 940 on March 31, 1986. Shortly after the Boeing 727 took off from Mexico City en route to Puerto Vallarta, an overheated landing-gear brake caused a tire improperly filled with air instead of nitrogen to overheat as well and explode, rupturing fuel and hydraulic lines. The ensuing fire and crash killed 167 passengers and crew. However, unless your driving habits are of the X-treme variety, the chances of your tires catching fire anytime soon are slim.
      Overall, filling up with nitrogen won't hurt and may provide some minimal benefit. Is it worth it? If you go to some place like Costco that does it for free with new tires, sure, why not? Elsewhere, though, I've seen prices quoted as high as $10 per tire, which is way more than I'd pay. Rather than shell out for nitrogen, you'd be better off just checking and adjusting your tire pressure regularly, something the NHTSA says less than 60 percent of U.S. motorists actually do.

            • Cam bat campii aia in aprecieri....la drumul asta pe care l-am facut asa in scurt 5000 km...am descoperit un singur dezavantaj la masina mea.....are rezervorul mic....clar...40 si ceva de litri ..la o medie de 150-180 km /h in autostrada nemteasca masina mea consuma 10.9-12 %....deci trebuia sa fiu cu ochii pe benzina sa nu raman fara.....in rest..fara probleme.
              Our AWD differential is too weak to propel the car when front traction is lost.....

                Vorbesc Vorbesc. dar nu prea am ce sa zic!
                Merge f. bine nici o problema. nevastamea e incantata de cum merge si de cat de relaxant e in ea.
                De vreo 4-5 zile am mers numai cu ea (mi-au expirat nr. rosii la civic). consumul mi-a scazut binisor cu cauciucurile astea de vara.

                    • Am o problema cu masina asta, de fapt cu amandoua. nu se intampla nimic notabil cu ele. Sunt vorba aluia de la fifth geat plicisitoare. vreau sa spun si eu ceva sa mai povestesc despre probleme si alte nebunii si dupa ce imi obosesc creierii cate juma de ora nu gasesc nimic ce sa spun. nu scartaie nimic, nu tremura sau nu bate. consuma carburant si merge.
                      Cu adevarat plictisitor. cred ca ma mut la masini italiene, ca sa am activitate mai multa.
                      Dc tot nu am ce sa va povestesc de masini nimic, atunci sa ma laud cu faptul ca de o saptamana sunt in curatenie si am casa cu fundul in sus. Am promis solemn nevestii ca e ultima oara cand mai fac greseala asta.

                      Ps. Crv-ul prin oras a scos pe ultimii 200km 8.8.

                      • v-am vazut ieri la Mobexpert cu ceva in mana!masinile japoneze nu sunt de dat pe nici un fel de masinii italiene,germanee etc!
                        am vazut civicul acum 1 ora si arata superb,dar cum ati reusit sa il urcati pe trotuar?

                          • Consiliul National pentru IMM: MFP sustine ca FMI solicita impozitarea tuturor firmelor
                            de Ioana Morovan HotNews.ro
                            Marţi, 7 aprilie 2009, 11:36 Economie | Finanţe & Bănci

                            Reprezentantii Consiliului National pentru IMM din Romania au declarat ca in discutiile dintre partenerii sociali si Ministerul de Finante, legate de impozitul forfetar, "s-a ajuns la un pseudosoconsens cu Ministerul de Finante. A fost un circ acolo, ca la piata. MFP a argumentat ca introducerea impozitelor chiar si pentru firmele cu cifre mici de afaceri este solicitarea FMI", a explicat Florian Pirvu, vicepresedinte al organizatiei.
                            "S-a ajuns, printr-un pseduoconsens, la urmatoarea concluzie: impozitul forfetar trebuie introdus cu orice sacrificiu necesar din partea MFP. Va fi eliminat pocentul de 0,5% din cifra de afaceri. Dar toate firmele trebuie sa plateasca impozit, dupa urmatoarea grila, raportata la cifra de afaceri:

                            impozit de 500 euro pentru CA intre 0-12.000 euro
                            impozit de 1.000 euro pentru CA intre 12.000-50.000 euro
                            impozit de 1.500 euro pentru CA intre 50.000-100.000 euro
                            impozit de 2.000 euro pentru CA intre 100.000 - 1.000.000 euro
                            impozit de 2.500 euro pentru CA intre 1.000.000 - 2.500.000 euro
                            impozit de 5.000 euro pentru CA intre 2.500.000 - 10.000.000 euro"
                            Florian Pirvu a mai spus ca au existat discutii aprinse legate de faptul ca o firma ar trebui sa nu-si mai ia masini in dotare si cu ele sa nu circule decat directorul general. Compromisul - sa se foloseasca masini cu o valoare de maximum 30.000 de euro.
                            Cea mai aprinsa dezbatere a exista, potrivit lui Pirvu, pe drepturile de autor. "A fost un circ acolo ca la piata", a spus acesta. In concluzie, este posibil ca drepturile de autor sa fie eliminate.
                            Pirvu a mai adaugat ca se asteapta adoptarea ordonantei de urgenta mercuri, 8 aprilie. "Doamna Gratiela Iordache a spus ca grila de impozitare este o solicitare a FMI", a spus acesta.
