Not really dumb, thanks, just uninformed. I'm driving a 2004 Safari SL 2wd and I'm just trying to figure out how wide I can go with stock alloy rims. Just don't like the skinny tires on the back. Strictly a looks thing. Thanks for the responses so far. :yawinkle:

A 205 is not a stock size for an 2004 van.
Stock size would be 215/70 16
You will also want to keep in mind the 4 Wheel ABS System, that relies on tire rotation speed.
Good Luck, Jim

You could go to a 235/65R16, 245/60R16 or 255/60R16 tire and it would be close enough I think the ABS would still be happy.

Its the "I Think" part that I would like to know for sure.

If I knew that, without a doubt I would throw some fattys outback in a minute.

But... On the newer stuff (4 Wheel Disc) I just don't know.

Who will be first, or who knows for certain?

The ABS will still work just fine. The ABS for the rear wheels is read from the sensor on the tailshaft of the transmission. I changed my rearend gear ratio from 3:42 TO 3:08. The ABS still works fine even though the tailshaft is now turning at a different RPM than it was with the 3:42 at any given speed.

I had abs on my 94 rear drive Safari and it had 215/70R15 on front & 245/60R15 in the rear and I never had any problems at all.
Recently bought a 1989 Astro RS from Florida. Replaced stock engine witha 1997 5.7 vortec with TBI and replaced transmission with rebuilt 700R4 with mild shift kit.
Bought on Monday the 16th of April 2012
