FRONTS: 235/35R19
REARS: 295/30R19


on 10" wide rears with correct offset for wide body

and 9" fronts

Carlo_Carrera

The fronts will fit fine but rears might rub the fender liners. Also that diameter ratio front to rear is not compatible with the AWD or PSM systems. The front to rear difference is too great. Ideally you want the front diameter to be equal or slightly larger than the rear.

Consider 245/35-19 with 285/30-19 instead.

I thought as long as they were within 3% it was ok? thats only 17 revs difference in a mile

Carlo_Carrera

17 rev per mile difference is a lot and right on the edge of what the AWD/PSM system can handle. You might trigger PSM issues with those. Do what you think is best but I think the sizes I listed are a better solution.

Cant find Winter tires in that size...

Carlo_Carrera

Tirerack has two choices and there are other brands at other sites.

Maybe I need to find some 19" wheels as I have had zero luck getting anything to fit my stock twists. Tire Rack *may* have some on order but they're out of production so they can't be sure. They don't even have a new wheel/tire combo I can do. Getting discouraged....

Carlo_Carrera

Are looking for snow, all season or performance tires for your twist wheels?

Hosewater2

Studless snow tires. I have Blizzak LM-32s on order, the front tires are actually the issue, they are out of production but the rep said Bridgestone had a pair left over so have been waiting for those for the past month. The rep has been awesome, just been hard to get an exact status update. I was out of town last week when we got 6" of snow, thankfully it had all melted by the time I returned.

Carlo_Carrera

Yes, snow tires are tough to find in 18 inch sizes. You are right, you might be better off going to 19 inch wheels.

Carlo_Carrera

These aren't full on snow tires but they might work for you. The sizes are good for the AWD/PSM system too.

Wow these might be it. Getting a status update on my Blizzaks today. I ordered 275s in those too, good to know they'll work if stretched a bit.

Carlos , it has been a few months since you gave me the advice to get this size 19" tire and wheel combo , but I ordered the rims from forgestar and had them make me a special offset 10" wide rim for the winter tires , and ordered the michelin alpin in the 285/30/19 and 245/35/19
I just got them all mounted up and they appear to be quite a bit taller than the 18" setup I have ( my car is in the shop till next week so fitment is not available at this time, I am just nervous will these fit my car for sure ?
I spent a lot of money on these and am just nervous, will the fenders need to be rolled?

Carlo_Carrera

I run those 19 inch sizes on my Turbo and they fit with room to spare. They are only 3/4 of an inch larger diameter than OEM 18 inch sizes. What 18 inch sizes are you running?
