OEM tire replacement by pietwo

I've averaged about 1K a month in mileage since I bought my 2005 LS430 in Dec. 2005. I wasn't particularly happy with the OEM Dunlop 5000's which had issues such as hydroplaning, thumping and a short tread life. I wouldn't buy them again. I thought I had standard wheels and tires but now find I have a low profile tire on an 18-in. rim (245R/45R18) and everything I've seen so far are "performance tires." The question is whether anyone knows of a "less sophisticated," run of the mile non-hydroplanning tire for this rim; absent that, I be interested knowing what tires others chose as replacements and for what reasons.

I own a 2005 LS430 that I purchased in May of '05. It has 37K miles on it and is in pristine condition and I want to keep it that way. I recently purchased a second vehicle to use as my "daily driver" (a smart fortwo) and use it almost exclusively. I plan to keep the Lexus as my "real" and have been driving it to work about once every two weeks, about 10 miles round trip. How frequently should I be driving it to keep all the seals, etc. in proper condition? Your thoughts?

TireRack is a good source of tires. Here are 85 tire choices from them in the size 245/45R18:

I still have the original tires but I will probably consider one of the several Michelin choices as replacements. For each tire, there are lots of user reviews as well on that website. Happy Hunting

Once every two weeks should be fine. Since 10 miles is still a relatively short trip, so keep on top of regular oil changes. I would suggest no more than 3k miles if using regular oil, or no more than 5k if using synthetic oil. Always use a good quality filter. If you have Smart Key, you may want to use a battery tender to prolong the life of the battery. Over the long run, you may want to replace the timing belt according to years and not miles. I would also suggest having the brake fluid replaced every two years and the coolant every four.
 
Even if you do not listen to me, this car is very well engineered and can take a lot of service use without a problem. You certainly can look forward to a long and generally good ownership experience.

Thanks for the advice vcheng. I'll plan on changing the oil according to dates rather than mileage too. So far this car has been flawless and has never had a reason to go in for service other than regularly scheduled maintenance at the dealership. I'm looking forward to enjoying many years of pleasure from it.

Catalytic converter... by wwest

225,000 miles on our '95 and it appears I need a passenger side catalytic converter.
 
New spark plugs, new downstream O2 sensor yet code persists.
 
I can buy new one, direct fit/bolt up, on Ebay for $120 to $150, anyone used one of these...??
 
Price seems to low....

P0430
 
Low catalyst efficiency bank #2.
 
I've been assuming the documents are correct and bank 2 is the US passenger side.
 
I thought the catalyst was going to be extraordinarily expensive (not to mention WORK..!) so after oil & filter(air & oil) change, MAF inspection/cleaning, I when for the O2 sensor and spark plugs first. Looks as if it actually is the converter.

I think I agree with your strategy.
 
If you are keeping the car, an OEM catalytic converter might be the way to go, but probably not worth it. How is the rest of the car in terms of condition?

Beautiful, excellent, drives like new but with just a wee bit of brief smoking out the exhaust upon WOT.
 
OEM would be about $800 DIY.
