Yes, with an XL load range rating and a load index of 105, higher than other tires for the RX in this size, the sidewalls need to be extra tough and perhaps without as much flex. Definitely a tire for someone who does not mind a stiffer ride than the OE tires provide.

Hy,
Which summer tyre is the best for the RX 450h 2010 (235/55 R19 105V)?
Recommendations of My dealer are:
PIRELLI Scorpion Verde
BRIDGESTONE Dueler H/P Sport
MICHELIN Latitude Tour
CONTINENTAL Sportcontact5
Bridgstone and Michelin are 'out'.
Pirelli and Conti are almost same, conti maybe more sportive not really ECO (as Ecocontact5) and has got more grip.
What do you recommend?
Thx,
FDToth

Just spotted the following review from tirerack for Bridgestone Ecopia 422. It seems to reduce the bumpy ride feel on RX350 and sounds very promising.

2010 Lexus RX 350 FWD More Tire Reviews for This Vehicle
No Photo Available Buy/More Info
Bridgestone Dueler H/L 422 Ecopia
Miles driven on tires: 100
Location: BOCA RATON, FL
Driving Condition: Combined Highway/City
Driving Style: Average
Initial Review, 100 Miles on Tires
April 13, 2014
2010 RX350 Bumpy Ride Suspension Issues Finally Solved with Bridgstone Ecopia 422's
Compared to original Bridgestone 400's, these tire are a big improvement in ride comfort, quality and performance.
Tire PSI is extremely important on the 2010 RX350 - This is the new SUV's 1st model year - and Lexus did not get the suspension tuning right at all.
(A new 2014 has a much more forgiving suspension, by a mile).
I run at 32 PSI Front and 36 PSI Rear and the car handles nicely - for a FWD
SUV. Still not anywhere close to my old 2001 Jeep Grand Cherokee - RWD Only
- maybe that's why I like the higher PSI in the rear tires.)
Also - The Lexus Dealer always sets Tire PSI to 37lbs - since this eliminates
a Lexus known bug (no recall yet) for a low tire pressure warning indicator.
(Funny, when the Lexus engineers originally ran this car on the test track - they ended up stamping 32PSI Front and 32PSI Rear on the inside door jam??
**** 37 PSI on the 2010 RX 350 (FWD) simply does not work with this car.
All you get is a jittery, twitchy and choppy ride.
I am very happy to report, that on my particular 2010 RX 350, withthe 422 Ecopias, and my own PSI settings, the car does handle very nicely.
Expect double the comfort as compared to the original Bridgestone 400's.
I would certainly buy these tires again since they helped ride quality, but also I look forward to some day owing a 2014+ RX350, where the tires don't have so much impact on ride quality.

This is for a 2006 RX330 with 18" wheels. The two tires both come highly recommended on this forum and cost basically the same price so I'm wondering which would be better. I live in Florida so these will thankfully see zero snow or mud but they will see rain.
Thanks!
Thanks!

The Alenza Plus is too new for much data. Only one CL member has installed them on their RX so far from what we have seen.

Both are available at Costco. The Ecopia has been giving owners a nice quiet ride from the looks of things.

Got a set of NITTO 421Q mounted today. They have decent specs and hope to get many miles from them. But the pricepoint was what really sold me. I own a set of NITTO Crosstek CUV for my Highlander and have had nothing but a good experience. I will update when I get a few miles on these new shoes.
