Hell, i friend of mine too his E36 M3 to TireDiscounts I think, or maybe SSTire. Anyhoo. They were to replace the front and rear tires, which were supplied and marked as to which tire to wheel combo it should work. Smaller tires in the front, wider tires in the rear, smaller wheels in the front, wider wheels in the rear. almost most if not all BMW's, im not a bmw tech, only vw, so im not totally sure on all tire combos. BUT
They put the wider wheels on the front with smaller tires, and then smaller wheels on the rear with the wider tires. Stretch and Poke to the fullest lol.
After he picked it up, he didnt even sign the paper work, told them stright up they were Stupid ************ ers and had them fix the issue, refund him all the money, made a big enough stink about it, that the boss at corperate called him and he flat out said he will not use them anymore, tell everyone he knwos not to, and bla bla bla. They tried to give him so much free junk but none of it mattered.
crummy part is most BMW drivers who dont use us for tire issues, us them in town as well lol.
