I've been searching all threads on awd staggered setups but none of them have the linea corsa dynas.These are the specs that wheeldude sells them in. What tire size can i go with without rubbing, but also safe for an AWD. I will be dropped on h&r's also. I would appreciate any input, thanks.

Specs:
Front - 19x8.5 +38mm offset
Rear - 19x10 +43mm offset

there is no "safe" staggered tire size setup for AWD cars, period...

even the smallest difference in diameter could potentially be fatal for the differential and couplings...

thats not to say that no one has done it, but, you might get lucky and never have a problem with it, or, you might be unlucky and end up spending 2-4000 dollars on replacing parts...

the only AWD vehicles I know of that use staggered tire sizes are some of the exotics, like Porsche and Lamborghini - they have specific tires with specific diameters they use to make them work properly...

manufacturers rule is to not replace even two tires if the other two are worn 50% or more (more than 4/32's or less, depending on tire / manufacturer / vehicle manufacturer), and that on an AWD vehicle, you should NEVER mix tire sizes, tire manufacturers or tire models... different models of tires and different manufacturers of tires can vary enough to cause driveline issues...

I know the danger but there is an icreasing amount of is250awd owners that are getting the right setups.

I just wanted to know for this specific size of rims, what would be the correct tires to use.

Thanks for your input though.

thats the thing - they are not getting the right setups... they are just hoping that they get rid of the car before the car has problems...

here's why...

if you do the math, you see that 275/30-19 has a theoretical diameter of 25.49" and that 235/35-19 has a theoretical diameter of 25.47" pretty darned close huh... Bridgestone offers this setup and claims the same 25.5" diameter for both, but at the same time, different treadwear ratings... weird huh... that means there is something different about the tires that they aren't exactly publishing... Michelins setup in those sizes have different diameters listed for each tire, same for Pirelli...

not a chance I would take, and for what really? so you can look cool? I think the cost of potential repairs would outweigh the cost of looking cool... there are plenty of non staggered GS's out there that look great...
