FYI, I don't think you can even get 30x9.5x15 in with the stock arms.
Tirerack specs says that the BFG AT in 30x9.5x15 have a diameter of 29.5
inches.

My 235x70x16 BGF MT are listed at 29.2, and I cannot imagine getting a
larger tire than mine in there without replacing or grinding the trailing
arms - there is about 1/8" clearance. I think many people that have seen my
syncro westie lately will agree. It is at the limit ( I have OME shocks and
syncro.org springs. http://volksweb.relitech.com/party/2002/tomstreet.jpg

I think John Wessle runs the 30x9.5x15, and I won't speak for him, but I am
pretty sure he had to grind down and reweld the stock trailing arm flanges
to get clearance.

But if you are not interested in the exact limit, and want to break on
through to the otehr side, you can get the 16" trailing arm info from Derek
Drew. His syncro madness area has links to discussions of superlarge tires.

Dont forget to change your ring and pinion gears!

I understand to mount REALLY big tires on your syncro you
need to upgrade rear trailing arms to 16" type. Where do I
get some? How much are they? Anyone have part numbers?

Also, assuming one makes this upgrade and goes to syncro.org
springs or the fastforward lift kit, how big of a 15" tire
can you get back there?

It seems like 30x9.50/15 is as big as you can go without
doing all of the above (assuming you don't care about
carrying the spare in the stock location) is this true?

Thanks,
Chris
