Hey everyone I need some help on what tires to run on my awd is250. I have some staggered work vsxx 19x10 +15 19x11 +38 wheels and I need help of what tire sizes do I run to make the rolling diameter as close as possible to each other. Thank you ahead of time.

 

Welcome to CL.

IMO, run the stock tires and wheels. You will be less-likely to have problems.

 

Did the vehicle have an optional staggered setup available from the factory? If so and you want it, mimic that. Otherwise you'd introduce understeer, which for many of us is undesirable. My understanding is that when a staggered setup comes from the factory, they do so for grip, and they dial out the understeer.

 

I believe the stock tire spec for the staggered factory IS250/350 is P225/40R18 front, P245/40R18 rear and the diameter comes out to 25.0866" Front & 26.0315" Rear. Use tire diameter calculator sites like this one - https://robrobinette.com/tire_diameter.htm and put in your desired tire size and see what size diameter they come out to. You might want the diameter to close to stock as possible to keep the speedometer reading accurate.
