They say the left front tire is the tire that is needed the least. It is just along for the ride. It barely wears at all. So why are prepping all of our tires? I understand you dont want the LF to duro 65 or anything like that so I know we should put some prep on it to get it down around 50ish but is it neccasry to be doing your tire program on it. I have a prep routine for during the week, and at the races but is it necassary to do the left front. I dont understand why we do all of the work to the left front when it isnt needed very much.
