Question? Rx450H Tyre Wear

[Ray1628]

Just got a 2010 rx450h with 51000KMs from local Lexus dealer. The current tyre depth is just abt 3 - 4mm. Dealer said

according to the system this vehicle was still with the original tyre (BridgeStone) and they could replace a new set

for me.

After purchase the deal told me this is the 2nd set of new BridgeStone 235/55/R19 tyres for this vehicle already. So

they cannot replace a new set for me.

But the interesting thing is the sales says that the life of tyre is abt 40000 - 60000kms. I also asked my friend, a

vehicle specialist with more than 10 yrs exp, he also says that 40000-60000 is normal if the car has been treated

properly.

The one I just got has full service history at local dealer so I think it is under good condition.

So that means the original tyre of RX450H can only last for less than 30000kms! And it happened for 2 set of tyres!

I just wonder how long the tyre can last for other RX450H owners.

I was confident with the Lexus technology. But if say that less than 30000kms is the normal tyre wear then it just make

me so disappointed and unhappy of the local dealer

Is it normal or I just met a tricky dealer?

G'day Ray, welcome to the club.

Sounds like the dealer's having a lend of you. My RX350 had its first new set of tyres around 70,000km and was still looking good on its second set (Kumhos) when i sold it at 107,000.

There are a number of factors which will accelerate tyre wear - pressure (either over- or under-inflated), wheel alignment (both front and rear), tyre balance (though unlikely ever to apply to a complete set), road conditions and driving style. So if the previous owner always drove with half-flat tyres on rough roads and spinning the wheels, then yes, 30,000 is about right. In the real world you should get a lot more than that.

An easy way to roughly tell whether you are on the 1st or 2nd set of tyres is to look at the manufacturing date of the tyres. Have a look here https://www.google.com.au/search?q=tyre+date+code&espv=210&es_sm=93&tbm=isch&tbo=u&source=univ&sa=X&ei=mI9DU9rJDYXRkwXn9IDIDg&ved=0CDkQsAQ&biw=1172&bih=939

So if your date code is ??10, then for certain that you are still on the first set of tyres. Good luck and hopefully the dealer can get you a new set of tyres for free!
