Are these Ok to run? The stock IS350 AWD rims are 18x8/18/8.5 and these are 19x8/19x9.

I know they don't work with the 2IS AWD.

Thanks!

 

that should work fine as long as you keep the diameter of the tires the same or similar.

 

19 inch wheels would require even lower profile tires. Personally I won't do it with all the potholes here in Toronto.

 

I guess it would be 30 front and 35 rear profile tires. I'm OK with that. I can run stock rims with winter tires for the colder months. But I'm just scared the extra 0.5 inch will cause problems for the drive train.

 

Proper size would be 225/35R19F and 255/30R19R or 235/35R19 and 265/30R19 (what I will be doing).
As long as the overall diameter is same or close you would be fine.

 

as far as tires go. your best bet will be 225/35/19 & 265/30/19 for .2% difference in diameter

or

235/35/19 & 275/30/19 for .1% difference. this much difference won't really affect the awd
