tire wear

The tires installed on new Lexus are likely to wear out fairly quickly because they have a soft compound with a bias towards performance and handling.

If you buy replacement tires with a higher treadwear rating (>400), they will likely last longer than the originally installed tires.

If the wheel alignment is correct then the tires should wear evenly and should be near the rated life. For example, the "Michelin Latitude Tour" has a tread wear rating of 600. This means it should last about

Michelin Latitude Tour:

Use the Tire Diagnosis page on Michelin's site:

Also, the tires listed for the RX350 on Michelin's site:

-- Energy LX4 has a tread wear rating of 500 (~50K miles).

-- The Latitude X-Ice is a winter tire. They do not list a tread wear rating on the site.

One thing you need to be aware of with tire tread warranties (from most if not all companies) is that if you have suspension or alignment problems (such as uneven thread wear), then the warranty if off. but in any case, dig up your receipts and see if you're still covered.

I'd suggest you get your next set of tires from Costco. Look for the $70 off coupon for a set. Good service, free road hazard warranty, lifetime rotation/balance and free nitrogen fill.

Thanks for the replies.

The original tires on the Lexus are Michelin Energy MXV4 S8. Treadwear shows 440 on the sidewall..

one other note.

some of the reviews on this tire (Tire Rack.com) were very good, but others indicated the same as myself, very poor mileage.

my tires are wearing evenly so I don't think alignment is a problem.

Thanks
