I was going to pick up some people yesterday and drove just fine for the 20 or miles. However, when i got 2 passengers on the passenger side of the car, things just went for the worse. i think i had about 200 lbs front and 170 lbs in the back. What happened next i was shocked to understand. the rear right tire started to rub, and i didn't realize it at first. i got on the highway and the tire shredded on the inside line. Completely destroyed tire. granted they are least 2 years of my ownership that i had the car for with 20k miles on it, but the question I have, is what is the maximum weight that can be applied without stock tires rubbing.
i'm running 135's with 255/35/18.. Stock suspension.
Could my suspension not holding compression and causing it to rub? i checked my other tire today to get the size, and noticed a gash on the inside track again on the other side. it's about 1 inch long and i would say 2-3 mm deep at the deepest part.
any input? also where's the best place to get tires for our toys?
btw the tires i'm running are bridgestone potenza RE760. any recommendations for tire here in chicago? i have a winter set so i just need a summer set. no crazy autocross or highway speeds of more than 80. i like to kick the car sideways once in a great while, but mostly when it's slightly wet and i'm not burning holes in my pockets.
