Re: 305 30 19 on stock rim?
WHY??????????????????
If your autocrossing you want both ends to turn and oversized rears are not the ticket, I have 18 245 on both ends so I can rotate and save the tires from one sided wear. Big tires is for straight tracks. I went to the wavetrack to get more looseness in the back and to be able to drift the back since the front dont know how to turn.
