Here's some info on my truck. It's an 05' Tacoma Dbl. cab 4x4 with the TRD Sport package. The tires that came on the truck are Dunlops Grantrek AT20 in size 265/65/17. I just got some Yokohoma Geo-Lander M/T 265/70/17 installed on stocker's Tundra/Sequioa 17's rims. Max air pressure on the tires called for 50psi. Discount Tires when mounted and balance the tires, they air them to 35psi. After installing them on my truck I check the pressure and set that at 40psi for fuel effieciency on the street. The truck with the stockers tracked straight like an arrow. Now with these M/T on the truck pulls slightly to the right if I take my hands off the steering wheels. The overall height on these M/T is about 1.5" taller than the stockers GranTreks. My question is..Do you think I ran too much air and since the truck doesn't have enough weight I'm rounding the tires off? Should I air them down alittle (35psi) or get my truck align. Truck is brand new and haven't seen dirt..not just yet.

have the alignment checked.....When done, it is to the vech and tire combo....not all but many cars go out of alignment with a full tire change so your story is not all that un common.....
