depand on the type and brand of the tire, also depand on the way you drive and where you dive. How hot or cold is it is an important elemant too. but in the avarage normal conditions:

Summer tires: 20K
Winter tires: 16k

Had potenza re050 as stocks. At around 13k mi, they started to exhibit minor slipping and traction control kick ins. It progressively escalated until 18k, I couldn't take it anymore and got some all season high perf tires to replace these. Check with tire gauge, could easily go another 3k, but in the face of winter I had no choice. So 20k if you do alot of highway.....15k is on the ball with most people.

my stock tires still have over 90% tread left. I can't get them to spin at all. and i have my 20"s on most of the year neways.

I'm going to special order my IS350 and was wondering if Lexus still offered 2 options for the stock tires. If so, which do you recommend? I'm more interested in tire life then performance. I assuming they don't offer all-season for the 18s, only the awd 17s.

sorry, unrelated question, could I special order the heated seats or can I only these if I pick an appropriate package?
