Default Awd IS250 with ISF rims

Does anyone know what tire size I should run with the ISF rims on my awd 08 iS250? 225/35/19?
Just don't want any rubbing.

I don't planon lowering it. Just keeping it stock. Thinking that ISF rims will make it look better. Just don't know what tire sizes to use.

225/35/19 is fine for the fronts. It will be too small to put that size on the rears. Generally people put 255/35/19 on the rears with the IS-F wheels due to the rear being a slightly wider rim.

No.
The only reason you would want to use spacers is if you want to bring the wheels out a bit to be flush with the guards.

Sounds good. Have you done this set up previously? If so do you have any pictures

Will have pics probably by the end of the week but I don't have an AWD IS. I've got a RWD IS250. I'm just waiting on some tyres to go on.
Otherwise do a search around here, plenty of pics of IS with IS-F wheels

no need for spacers, if your stock, 225/35/19 front 255/35/19 rear should be fine.

for fronts, stock for IS-F wheels are 225/40/19 (kind of chubby though)

I went to get my tires installed 225/35/19 and 255/35/19 and the tire installer said that set up will not work because of the AWD on the is250? Is this true? I've read all along that the tire size would work. Any input?

Yes 255-35- will not work on awd it will run faster then your front wheel. You need to run 255-30 series that works alot better. Stock diameter 24.97 & 255-30 is 25.03 diameter which is near to stock you can get.

So I will need 235/35/19 in the front and 255/30/19 in the back?
