My tires are 275/65/16. Hardly oversized compared to others Ive seen. And The pervious owner gave me a copy of the 100k service. Beyond that i dont know what was done. The shop I took it to(dont have an isuzu dealer in town) had never seen or heard of a VehiCROSS too.lol But i figured i was just geting some standard thing done( brake flush, diff. lube changed to synthetic front and rear, eng oil change synthetic, spark plugs, pvc, ect) Nothing vehical specific. The previous owner idnt even know how many owners there were before him! I couldnt pass on the price 6k! And everything works great, just that weird feeling when I make SLOW turns. I did go over a large bump once and had probelms with what i thought was torque binding for a while then it cleared up. And now it kinda back but just the front end not the rear. Well keep it comming guys. Ill take my VX to a brake place and see if there is any abnormal wear, maybe it time for some R1concept rotors!
