Would you trust 13 year old tires?

I don't know if this an apples vs oranges thing.

When I had my sportbike, I changed my tires (both front and rear) every winter. My bike was my only form of transportation, with a daily commute of 35 miles each way, plus my weekend beating on it out on the coast, or in the hills. Also long distance rides up to Tahoe a couple times a year. I used softer (not the softest) compound tires, and always paid attention to tire pressures. I could have gotten away with stretching the tires to last two years, but spending the money (about $300-$400) was CHEAP compared to death or injury.

My bike was a 435 pound missile plus my 175 pounds of blood and bone. How much energy could that deliver at speed? What does your car weigh?

Finally, it's not just your tires, but your entire suspension package. Keep that all in good shape because even if you don't give a **** about yourself, people are driving around out there with their families. If some cheap son of a ***** puts my son's life at risk, there will be more than hot words.
