Lexus RX new tyres - have poor lifetime?

[IGROK]

Hey everyone,

I have a 2023 Lexus RX with Dunlop SP SPORT MAX 060 tires, size 235/50 R21 101W. After just 3,700 miles, my tread depth is down to 6mm on the rear tires and 5.5mm on the front tires - from New
Lexus has informed me to expect a total mileage of 12,000 to 14,000 miles from these tires. This seems extremely low to me.

Based on a treadwear rating of 280, I was under the impression (thanks to Google) that these tires should last closer to 50,000 miles.

For context, I always run my tires at the recommended pressure of 33 PSI. I have a normal driving style, not a fast driver, and mostly do city driving.

QUESTION to community: Does anyone else with the same tires on their RX is experiencing similar issues. Specifically:
- What kind of lifetime mileage are you getting from these tires?
- What was the tread depth on your new tires (I couldn't find this info online)?
- Any insights from your yearly service on tire wear?

Thanks for your help!

I have Dunlop SP Sport Maxx 050's on my 4th Gen RX, at 25,000 miles fronts will need replacing shortly, rears are still doing fine.

Have you done tyre rotation? And how often?

[Spock66]

No I don't ever rotate the tyres, overall wear seems similar to other large cars I have had.

I got shot of my OE Sportmaxx tyres as soon as I could, awful things.  I fitted Bridgestone Turanza 6's instead.  Way better grip and ride.

50,000 miles, you will only get that impression off Google lol definitely not in the real world 🤣

City driving is the worst for tyre wear, lots of junctions, turns, stops and starts...
