The OEM Michelins on my 09 RTL just hit 50k -- still have more in them. But I have a long, steep, curving driveway, goes uphill to the road. (When my wife had a Camry, she'd make it halfway up in the snow, spin it around til it was facing downhill on the grass... She drives a Pilot now...) My last truck was a Suburban, and I loved my Toyo LT's. No problem ever on the hill. These P245s do okay, but I'd like to go to a year-round tire with a more aggressive tread. I know enough about tires to buy a set every few years... But I'm no expert. Why can't I find an LT or A/T tire in the OEM rim size (245/60/18)? Suggestions on a more aggressive tread? I'm not worried about a bit more noise or slightly harder ride. I want traction on snow -- without buying winter snows. Thanks for any advice!
