Allow me to open the can of worms known as tires. 

I live in the DC area and need to replace my OEM Bridgestones--on 18" wheels/RX 450h--soon. 

I'm looking for a longer-lasting, comfortable riding tire that is all season and will have a tread wear warranty of at least 60K.  Good wet weather braking would be a plus.  I don't need tires rated over 120 mph--I doubt that this vehicle could go that fast.  I won't be carrying heavy loads or towing a trailer.  The less money they cost, the better, though I realize I'll have to spend over $100 per tire. 

Suggestions would be appreciated.  Currently there are too many out there to even begin to contemplate, and I don't keep up w/ tires these days, anyway.

I suggest that you look at the customer ratings on and either buy from them or check locally.  There were two different sizes available for the 2015 RX450h - availability is going to vary depending on your size.

Many or maybe most major tire retailers will not sell you tires that have a lower speed rating than the ones that came on your vehicle with the exception of Winter tires.  Your RX probably came with H-rated (maximum 130 mph) or V-rated (maximum 149 mph) tires.

My wife's Prius can't get out of it's own way but it's a top trim variation and came with Z-rated (over 149 mph) tires and that's what we are stuck with buying for three-season use.  I just took off her Winter wheels/H-rated winter tires today hoping we're mostly done with snow and ice.

I've been buying almost all our tires at Costco for the past 18 years during one of the Michelin or Bridgestone sales.   Maybe other tire sellers do too but Costco includes lifetime balancing, rotation and flat repair in the purchase price.  I just had a flat repaired at Costco yesterday - in and out in about 30 minutes.

I've been to TireRack.  Only trouble is, I don't know which tires are good/better/best.  Guess I'll have to go back and do some more reading.  Thanks for your time, it is appreciated.

I've essentially stopped expending energy trying the buy only "the best" tires.  My main goal has become to buy tires that have been found to be reasonably quiet, that provide a comfortable ride and which are available at reasonable prices.

As much as I mind tire pressures and rotation schedules, I've never been able to get the rated life out of tires.  Tires are usually seen by manufacturers to be worn out when they have less than 2/32 inch of tread but by that time they are not safe on wet roads. 

Here is a current example.  The rather expensive Michelin Premier A/S tires on our Toyota Sienna Limited are rated to have a 60,000 mile treadlife.  The original tread depth was 8/32 inch and they are now (as of yesterday when I mounted them) uniformly worn to 4/32 inch tread depth after just under 26,000 miles.  If they continue to wear at the current rate, the tread depth will be at the 2/32 minimum at around 39,000 miles which is far under the 60,000 mile rating.

Do I want to be driving on these tires in rain when they are at 2/32 inch?  Maybe I will this time since the big selling point of these tires is their wet weather performance.  I've never submitted a tire warranty claim for premature wear even though I could have many times in the past but this time I plan to this time.  I'm getting a little tired (pun intended) of the warranty hocus pocus in the tire business.

On Costco--my favorite place to shop in the whole world--they do not list the correct tire size for my car!  They show the size as 17", but that's incorrect, the size is 18" and a slightly different aspect ratio.  So no matter what, currently it can't get "new shoes" there.

      So I shopped for tires (P235/55R19) over the weekend and received conflicting information from various tire shops.  I prefer to stick with Michelins but am not opposed to other recommendations.  However, the information I received over the weekend was specifically related to Michelins.  I used to have a 2001 RX300 Silversport and had about 4 sets of Michelin Defender LTX M/S tires over the life of the vehicle while in my possession.  Those tires were great for treadwear.  So, should I stick with the Defender LTX MS for the 2015 RX350 or should I go with a different Michelin or a different tire all together?  The other Michelin choices are the Premier LTX, Latitude Tour HP, and Primacy MXM4.  Thank you for your help & recommendations.

      I am a new member living in Alabama with a 2008 ES350 that has 57,150 miles. I purchased a set of expensive Michelin Defender's just a 3 years ago and only got 10,000 miles out of them. I am again in the market for tires an am in need of your help. My Lexus is in great shape. It only requires gas and oil changes. There are no problems and it is well cared for. It has never been in an accident and I'm not wearing out the brakes so there is no reason for the excessive wear on the tires other than they did not live up to the 90,000 mile promise. Can you recommend the best tire for my Lexus?

      I've lurked this site for a number of years, so I guess it's time I became an official member.  I bought my '07 ES350 new in '06 and it's been a great car....I plan on hanging onto her as long as I can.  She has the original rims, which are now leaking like a sieve in the cold weather.  I had no problems with tire leakage until I bought the first set of replacement tires, but ever since it's been a constant battle having the wheels "cleaned" and "sealed" at the tire shop.  I need to purchase a set of replacement rims but am undecided where to buy, what brand, how much I need to spend and all.  She's black, so I think silver or chrome would look the best. I have OEM 215/55R17 tires.  Suggestions would be greatly appreciated!
      (If the old rims are not out-of-round and just need a GOOD refinishing, I'll likely keep them on hand as an extra set.)

      Looking for recommendations for all season tires for 2004 RX 330 - the current size is 235/55/18. After doing some research I was leaning towards Michelin Premier A/S or Bridgestone H/L Alenza Plus.  My local tire store is recommending that I consider Cooper or Nokian and said to stay away from Michelin and Bridgestone. Any help would be appreciated!
