Hi,

New RX350 owner here. I am looking at tire replacement for my RX350 and noticed that Bridgestone Duelers do come in 2 sizes:
* 235/55R18
* 235/50R18

Any owners out there that bought 50-series over 55-series Duelers? How do you like them?
Obviously we are talking lower-profile tires here (129.25mm vs. 117.5mm) which I assume would mean harsher ride, feeling more bumps on the road, easier to bend the rim, etc, etc, but could also mean "improved" handling feel... I would also assume that car appearance would change as well with lower-profile tires. Any pictures to show?

Any feedback is greatly appreciated.

Kris

PS
Apologies if dup thread but I just could not find any info on this using the search...

You're looking at almost an inch difference in diameter, which is not recommended. Your speedometer will be inaccurate, your GPS may not track you well, and you may suffer from indigestion.

You could try a 245/50/18, as long as the extra width doesn't interfere with steering (i.e. rub the wheel wells etc.)

I agree with rcy. I would not change the diameter by almost an inch!

Thank you for the advice.
