Yes you are.

225 -35 front and 255-30 rear will work better for a little stretch. But 265-30 will work.

Apparently 225/35/19 and 265/30/19 is closest you can get with staggered and the same overall diameter....0.2 diameter difference where as 225/35/19 and 255/30/19 is .72 difference.

Heyy Guys, I have an Awd is250. Im buying 19's. The specs are

8.5 (F) + 38
9.5 (R) + 45

I know for the fronts I can run 225/35/19 Which is about only 1% different. But What tire in the rear to match? I dont know how the whole tire stretching business goes, thats my only problem. Thank you!

Hey guys, i have a question about rolling diameter.

I'm actually not running a staggered set up, i have 20x9 +38 all around.

i want to flush the rear, it only needs 10mm spacers a side i'd say, but 15mm would be really nice. Do you guys think that would throw the whole awd system off? because obviously the rolling diameter would change.

I'm thinking 10mm each side would be close to a 3/4'' difference?
and wondering if pushing over 1" rolling(15mm)diameter is too much?

do you guys need to know my tire specs?

^ Why don't you just get 15mm spacers for the rear instead?
