problems with tires balding on x5

[dreds2nv]

i like to know if any 1 out there has this problem.. first off i have a 2000 x5 4.4 and i notice how my tires were shreding from the insides all 4 of them and the rear got the worst end of it. i did an alignment twice. i had the 4.6 set which is 9.5 & 10.5 rims size with some toyo tires that are 275/40 front & 315/35 rear.. but for now i have the beyren wheels which are smeller than the 4.6 and they there 8.5 front & 10 in the rear with the same tires. some people say its a problem with the first modles with the x5 but they told to found out on here. so if any 1 knows about this please hit me up cause i'm about to get a new set of tires thank you
