All the tire service chains here in town offer free puncture repair and rotation every 10Mm with their tires. The repairs are usually limited to patching only. I personally don't agree with over-inflation, and If a tire was patched and over-inflated I think you'd be pushing your luck a bit too far. You'll likely be voiding the protection plan, as well as any tread life guarantee, by using the tires out of spec.
