Hey all, real quick question, I noticed today, on my SSR's, on the center lugs, they seem to be cupping a little, the rear of the lugs (the rear when they are on the top of the tire, when that same lug is on ground it would be the front). Is this a problem from too much air or too little? I am running 32 front and 28 rear, the rear look fine, should i drop the front to 30 and see if that helps? Thanks. Chris.
