The alternative is a es350, but I know she would like the convertible.

I still stand behind my comment that the savings in gas per year will wash out the added expenses in tire wear.

She currently drives a 2003 Gx470 with 185,000 miles. She works very hard and it's not like she is demanding a $50k to $100k new car. She would just like a convertible and we believe in Lexus(Toyota0 Quality/long life. As you can see by our current vehicles mileage, we get our monies worth out of our cars. The tire situation does worry me as it could get pricey. I will check with Americas Tire to see what they say. No chance of going to only 225-40-16 all around and rotate them? I suppose the wider rear rims won't do well on the front?

Out the door the tires would be around $913.00. So if I could get say 35K miles per tire, ( she drives about 15K per year) then about $500 per year. I just got 55K out of Pirelli P-7's on my 1999 Camry... So I guess the question is, if I keep the IS350C for 5 to 7 years minimum, then it would probably be worth it to get the squared rims?
