Tires - 2012 IS 250 RWD
#16
I have a 250 AWD with 18x8, 225/40r18 all around. I just swap the tires from Pirelli P zero to Continental Extreme Contact DWS06. You wouldn't believe how much ride comfort they improved. It feels like I'm running on 17" now, which is awesome! DWS06 are not as sticky as P zero, but the ride quality is night and day.

It seems I'm not too up to date with my tire info, but yes, Lou is right, 225/40r18 should fit all around. I stand corrected. I'd still be a bit concerned due to the different offsets (+45 vs +50) if they are the stock rims, may need spacers in the rear if OP plans on rotating the fronts to the back and vice versa. I'd need to research that though to be sure.

I’m keeping the staggered setup (225/40/18 and 255/40/18). For me, it strictly comes down to comfort and road noise.
Should I go with the Michelin Pilot AS 3+ or Continental ExtremeContact DWS06 tires???
The car will be based in Michigan (hot dry summers & cold snowy winters).
Thanks again for the help!!!

To add to my last post, thoughts on me comprising the staggered setup and splitting the difference with 235-40-18 all the way around? That way I can rotate the tires. As the CL members have called out, the rear wheels are supposedly larger than the fronts though...

If you want summer and winter tires Continental DWS 06 (DWS = Dry Wet Snow) are your best bet, they are fantastic tires! Read some reviews online, watch YouTube videos. Hope that helps.

My experience with Continental tires, The Extreme Contact DW was a disaster. The people at Continental were extremely rude and offered me no help. Thank goodness for Discount Tire I will NEVER buy Continentals again.
And to find out your rim widths, they should be stamped on the inner edge of the wheel and visible with the tire mounted. Just remove one of the rears and look.

Based on Michigan driving conditions, I'm going to go with the Continental Extreme Contact DWS 06 tires.
Now, assuming my car (2012 IS 250 RWD) does have staggered wheels, can someone please tell me the pros/cons of putting 4 of the same tires all around? In this case, 225/40/R18. Knowing the rears call for 255, my plan would be to have the tires (but not wheels rotated) at the necessary intervals.
Ultimately, is it that bad to have 225/40/R18 tires on the rear of the RWD IS 250 that calls for 255/40/R18?
**I have not confirmed that my wheels are staggered. However, I have stock Lexus 18 inch wheels, which everyone continues to tell me are staggered...

Yes for snowy Michigan I would definitely go for DWS06

I run 18 x 8,5" wide ISP Mode wheels with 225 40 18 on all four corners on my RWD with no problems. I can rotate them any way I want. I like the quiet and comfortable Pirelli P7, the only regret I have I should've went with 235 40 18.

I just confirmed my wheel sizes:
Front: 18" x 8" with 45mm offset
Rear: 18" x 8.5" with 50mm offset
Based on Michigan driving conditions (hot dry summers, cold snowy winters), I'm going to go with the Continental Extreme Contact DWS 06 tires.
With this information, can I safely get away with using 225 or 235 /40/R18 tires all the way around so that I can rotate them? Or, do you recommend that I stick with 225 in the front and 255 in the rear?
Thanks everyone!!!

I would find out first if DWS are directional tires, meaning they can rotate only one way.
Use this tire calculator https://tiresize.com/calculator/ (click on Tire Comparison) to see huge difference in overall diameter between 225 40 and 255 40. I have no idea why Lexus went with staggered wheels on gutless IS250 lol
I would use 235 on all 4 wheels. You can rotate them without having your car looking weird, the only difference is if you install 8,5" on front and 8" on rear that wider wheel will stick out 1cm more than 8". Such a small difference no one will be able to tell. You could also get 20mm or 25mm spacers to fill that extra gap when using 8" wheel on the back.

Thanks for everyone's input! I placed an order for the Continental Extreme Contact DWS 06; 225/40/18 in the front and 255/40/18 in the rears. I'll provide feedback once I have them installed. Optimisitc that I'm going to experience a smoother and more quiet ride than the current Chinese tires that I have on the car!

For those wondering, I purchased the car used from a private seller who put 4 Rydanz Roadster R02 tires (225/40R18/92W on all 4 squared).
These are the tires that I'm discarding for the Continental Extreme Contact DWS 06. They can be purchased at Walmart for $68.50 per tire...

I had the Continental Extreme Contact DWS 06; 225/40/18 in the front and 255/40/18 in the rears installed today. The car drives significantly better!
Question - what is the minimum tire pressure (PSI) that I can safely use? I'd like to use towards the minimum in order to achieve the smoothest/most cushioned ride.
