Yes that's the spec I have. 61 plate with  5 spoke 18'' alloys and those headlight units.

Have been told, if you have daytime running lights, you have xenons (?). But I've checked other 2011 Advance IS250's and they all have xenons in their descriptions.

OK, I have been using 8 - 10k xenons for years, had them on my Honda. I understand how they aren't as good visually but I just like the look  hehe  :P

The Xenon bulb size is D4S.

I don't think all Advance models have Xenons. Does your car definitely have them?

In any even, yes. You can swap the bulbs from under the bonnet (plenty of how-to videos on youtube), but you might need to remove the air filter housing (or at least move it out of the way). Plus, the washer bottle filler neck on the passenger side.

Pretty sure mine has xenons (2011, 61 plate?). Certainly looks it, and they seem to 'charge up' when switched on.

I'm wanting to get some 8 or 10k's in there, any good links on eBay or where ever?

Hi.

Just wondering what Xenon bulbs are used for the 2011 IS250 Advance. I have read H11, is this correct?

Also to replace them, do/can you go under the bonnet? Or do you have to go under the wheel arch or something? 

So what are the best tyres to get? I have always stuck with Michelin PS (gone through 2, 3 and 4).

OK checked the door and it says

225/40 88Y

255/40 95Y

I have the 5 spoke smoked 18'' alloys. I think they come with the Advance spec?

It was second hand and all the tyres are budget tyres.

So,

255/40 on rear

225/40 on front.

Does it matter about the speed rating? (W,Y).

My car is 2011.

And those are the tyres on the car. In fact on the front one tyre is 225/40 R18 92W and one is 225/40 R18 92Y!

I just wanna know if the 250 IS requires wider rear tyres? Does the Advance come with wider rear 18's? Or can I put the same size on all four?

Just looked.

Rear tyres are: 

225/40 ZR18 99Y XL

Front tyres are:

225/40 R18 92Y and the other is 225/40 R18 92W

Is this right?? Does this car need wider rear tyres? Does it make a difference? Can you put on tyres all the same size? 

I'm kinda lost here because I really don't know if I should be putting on wider tyres now. 

Hello, I'm a newbie  :)

I just recently moved over to Lexus from Honda. I now own an IS 250 Advance in Argento Ice.

Question though. Having bought the car (second hand from Lexus dealer) I noticed the rear 18'' tyres were bigger than the front tyres. Does this car require bigger rear tyres or is this just a mistake by the dealer?
