Also, how often are you doing the R&B with those things?
I wouldn't attempt any land-speed records (personal!) if I hadn't just had the tires rotated, balanced and checked over for ANY SIDEWAY/TREAD issues at all. And, how'd the last alignment go for you? Everything in spec.?
130MPH? GPS co-ordinated and confirmed?
And...when did you check those inflation numbers? When the tires were cold, not driven on yet for the day?
Your tires should be R&B at least every 7,500 miles...minimum. And there IS a difference when it's done correctly...you can feel it.
Do the R&B before you spend money on anything else...unless you like having less weight in your wallet.
