245/35R19 & 275/30R19 tires on stock rims

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...

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.

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.

Jesus loves you!

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.
