A little while ago I upsized to 245/35ZR19 fronts and 275/30ZR19 rears on the stock ISF rims (19x8 front and 19x9 rear). The tires I chose were Continental ExtremeContact DWS (DryWetSnow) tires. These are Ultra High Performance All Season tires with a Y speed rating (186 mph).

Overall, I am very happy with the tires. They have great dry grip for an all season tire, are very good in the rain, and actually not too bad in the snow.

I had to get an alignment after getting them mounted and balanced. This was because the tow angle in the front was off and was causing the car to be "floaty" at 80 mph+. The camber angles didn't need adjusting though.

Here are the best pics I could manage to show what the clearances are with the wider tires. I have experienced no rubbing whatsoever under extreme driving.

Wow,,, i would have thought they would be stubby on the edges but you are still going straight up and down, almost like the way that they should have came from the factory...

looks good, wouldn't mind more rubber in the rear myself
I agree, wider would be preferable. This summer I will be getting aftermarket rims with 255 front and 295 rear max performance summer tires...not sure which manufacturers yet though.

The stock rims with the A/S tires will be for late fall through early spring, and the aftermarket rims with summer tires will be for the rest of the year.

This is good! Thanks for posting this!
No problem. I know that I was wondering if they would fit for quite a while, and it was like pulling teeth to get somebody to verify that these size tires would fit.

It would greatly benefit everybody here if every time somebody did something new to the ISF, they would post a comprehensive review of what they have done, along with pics. A few minutes with the keyboard and camera can make it so much easier for everybody else.

There are a few guys here that do this very well, and I greatly appreciate the knowledge and time saved I have gained from them.

I totally agree with you Gymkata. Although, I find more DIY information at ClubLexus, like Caymandive's break pad replacement. Just thankful that he shared the link in this forum. Otherwise I wouldn't have known. Maybe I should also join the ClubLexus forum also, but why should I visit another forum if I'm only interested with the ISF?... Again, thanks to all you informative guys in this forum.

I got a chance to see how the Continentals drive in the snow on Saturday. Other than trying to start from a stop on steep hills, I was impressed at how surefooted they felt. Of course this is a powerful RWD car, so caution was in order. As long as you know how to drive in the snow, and can feel what the road is telling you through the pedals and steering wheel, you will be ok in moderate winter driving conditions.

Is your car lowered by any chance? Just curious as mine will be shortly.

On a side note about Club Lexus, I am a member there too and basically do not like a few of the folks over there as its full of snobs and folks who havent a clue about performance mods and also think you have to have posted more then 10 posts before you can share insight. This forum is slow to load but I get a lot more USEFUL knowledge here without the snobs and I appreciate it folks.

I like the format of things on this site better. I have been reading articles on CL a bit more lately, but I agree...there is more ranting and arguing over there. There is more content there too...but I still greatly prefer this forum to CL.

My suspension is stock right now...but if you look at the angles on my pics, the tires are still tucked nicely within the fenderwells. If you lowered the car a bit, I imagine that 245s and 275s on stock rims would still fit perfectly...I can't promise you though.

Thanks Fella, looks like I am going to try it. Appreciate your insight. Also I will see if anyone has posted the spring install and if not I will post a step by step on it.

Agreed, however, It is NOT that they don't know about performance mods, in fact some are very knowledgeable. Some simply have ALL day to sit in front of the computer and banter back and forth. As you can see, my post usually take place early in the morning or late at night... i.e. family and work come first. The attitude of general arrogance turns people off. I honestly feel there are some people whom simply put are "internet bullies/tuffguys" with no serious social life to speak of. My cars are my "pleasure's, NOT my life. If I loose one today, I will buy a new one tomorrow, it's that simple too me. I "like" some of my cars more than others, but I LOVE none. As I have aged I have learned many things, first being family first, respect ALL second, and third but not last the famous 2 to 1 ratio... You are half as smart as you think you are and your father is twice as smart as you think he is.

Thanks.

This information is helpful.

Pretty amazing (and brave) you'd drive a tire this wide in the snow.

This is likely the tire sizes I'd install when I need replacements for my summers.

No problem. I only drive this in very light snow. If it is going to accumulate, I drive my truck only.

"Foaty" its floaty because the front tires are too big for the OEM rims. I had this same issue with my invo's. To fix the problem go 235/35/19 or the good old stock size 225/40/19.

Gymkata, did getting an alignment help with the "floaty" feeling? I am would like to go with the same tires/size for my replacement, but not if it isn't safe feeling above 80.

thanks

Alignment is not going to fix the problem, your tire sidewall is the issue, the lower the profile the less flex in a turn or move. I had this issue I dropped to a 235 35 19 y and that stopped the flex the 245 35 19 is too tall.

No - The stock tire is 26.1" tall the 245/35/19 tire is 25.8" in OD. The 275/30/19, 245/35/19 combo will do just fine on the stock rims. 235/35/19 is really too short at 25.5" in OD.
