proper tire inflation?
well i finally got the Michelin Cross Terrain 255/60/17 to replace the stock
Michelin LTX M/S 245/65/17 ... first impression is: they are great! i feel like i got a pretty good deal on them at Tire Rack ($120 delivered) and the dealer did the mount and install for $54.16 for all 4 tires ... i could not believe that the dealer actually had the best deal on install ... on the way home i checked the tire pressure and it ranged in the upper 30's PSI in all 4 tires (not cold) ... has the dealer over-inflated the tires? what is a good way of figuring out the approproriate inflation pressure for this size tire on an infiniti QX4? |

You are not all that different a size tire than stock, so the factory pressures listed in the Owner's Manual would be a good place to start. Here are some ideas you might try if you want to experiment a little from the http://www.4crawler.com/Diesel/Tires...roperInflation -- Roger |

You'll likely not come up with one answer or one pressure. I've run 20-22 psi in my 33x10.50 BFGs on the highway and they do OK, no signs of overheating. But for extended high speed driving, I generally run about 30 psi or higher. Start out with the suggested inflation specs for the vehilce, often in an Owner's manual, sticker on the door jamb or glove box, etc. If that feels too soft, increase the pressure, if too firm, decrease it. Watch the tread wear and tread contact patch and come up with something that works for you, your driving style, your vehicle and tires. -- Roger |
