2012 RX350 Max tire size
Im looking to buy tires for my 2012 RX. It’s the one with the 19 inch option. So the factory tires are 235/55 R19. I am kinda wanting to go one size wider. I would like to go 245/55 R19. I do long highway travel for work. Don’t judge me but I’ve always thought , more meat on tires , the softer the ride. I do not want to go one size taller. I want to go wider. Is there anyone here that has done that? Pictures ? I just want to make sure it does not look dumb

255/50/19 is almost exactly the same diameter as stock and what I have on my RX. It is a popular size that is used on many other vehicles. It looks great.
I did get 8 inch wide wheels. The stock wheels are either 7 or 7.5 inches, I forget. They should fit fine on your stock wheels and improve the ride if you get the right tire.
Consult with Tire Rack tire reviews to identify softer riding tires.
If you replace your rear shocks with Sachs 316603 it will ride softer. The rear shocks affect your ride more than the front. Rock Auto has them for about $61 each and any local shop can install them in less than an hour. There are only 2 bolts. FYI Sachs is a German brand that supplies many German car companies and is owned by TRW.

Not better but different. KYB is a little stiffer than stock. The Sachs is softer than stock. It depends on what you are looking for. I found the Sachs too soft and removed them after a few months to install Bilstein B6 rear shocks. I was looking for better handling. If you want a smoother ride, get the Sachs.

Bilstein has consistently offered the best build-quality and longevity in the global shocks market for many years. Some folks find the ride a bit stiffer than they prefer. You may want to research the Bilstein B4. It typically provides a softer ride than the B6. When my wife's 2015 RX350 (now approaching 73,000 miles) needs new shocks, I will install the B6.

Bilstein does make the best struts and shocks. However, most places online are out of stock at this time. Another member was recently trying to find B4 struts and shocks and none were available.
FYI there are other threads on this, but the Bilstein struts and shocks for the RX are actually those listed for the 2014 - 2018 Toyota Highlander 3.5 V6 FWD. It has the same suspension as the RX. The B4 is for the regular model and the B6 is for the F Sport model, or if you want to make your regular model handle better.

Bought Pirelli Scorpions Strada A/S. 245/5519s. Look slightly wider but not by much. Rides great. Does not touch when turning all the way either right/left. I will post pics. Think it’s great for long highway trips like I do for work.

I'm also looking for wider tire to fit the OEM fsport rim for my 2014. Im thinking 245 50 19 which I have on my Acura RL (I know its a different car but looking for that type of handling). The stock tires are crap especially taking corners. I open to suggestions also for tire brands best for this vehicle. Michelins?

Go to www.tirerack.com and check out the tire reviews. Try out the tire size calculator under tools at the top of this page.

Have the Sachs / TRW on my 2008 RX350. They're a little soft for my taste but very comfortable and still offer dependable handling. For a comparison, it feels like the OEM Sachs dampers on a BMW, Chrysler 300 or Porsche Cayenne / Audi Q7. Even the softer Sachs setup on my 2008 RX350 was able to easily out-corner our heavier & larger 2014 RX350 with Bilstein B6 or an Audi Q7 / Cayenne base model (It also had Sachs).

Use the tire rim calculator to see what larger size is close to the original diameter. That is why I chose 255/50/19 as it is almost exactly the same diameter as stock.
