Unless you're wheel spinning in 2nd/3rd that won't make a noticeable difference. Hard cornering and wheel spinning are what tyres hate...and I do both on a regular basis. 
Is it just the outer edge wearing badly? If so, it's likely to be the tracking, though 306's do have a tendency to chew edges even when the tracking's correct, but not that quickly usually.
