Re: sp3000a tyres crack in side wall
Sidewall cracking is a known issue with the first few batches of SP3000s which has been resolved since. However, at 37,000 these tyres would be pretty worn out - I'm guessing 70-80%. Even if they do replace them under warranty (which I highly doubt considering the number of kays you've clocked up) it'd be on a pro-rata basis, which means you'd have to pay for the used tread.
However, speak to Beaurepaires Shepparton, 298 High St, 5821 9488.
