tire size

[jamesonsdad]

good morning all...i have been reading some posts that oh9 owners run 33's and seem to be better for highway speeds,my question is ;can i run 33's on my cucv vs. the standard 31's on it now? or will i need to lift it? it seems that stock height has the clearance but thought i'd get some feedback....thanx

Welcome aboard!

You can run 33's on the 1009 without any lift, I have 33x12.50's on mine.
Depending on the tire itself, you may get some rubbing on the front fender well edges at just the right angle/flex. Oddly enough, one of my 1009s only rubbed on the left fender, the other only on the right. On the one rubbing on the right, I whacked a small piece of the fender off with a dremel, on the other I whacked the fender lip with a BFH, now neither rubs. With a less aggressive tread, neither would have rubbed.

I'll dig up some pictures and attach them, they show what I mean.

Pawnshop has some 33x10.50s on his, they don't even come close to rubbing.

Cheers

thanx...i'll look for 33 10.50's my 31's are like new but i do travel the northway every day to work and back ...how much of a p.i.t.a is it to swap in a th700? at 60 mph she begs for another gear...

Measure your tires. Ground to top of the tire. My stock 31 x10.50 tires were actaully 29 inches tall. My new BFG A/T tires which say 33 x 12.50 on them are actually 32 inches tall. That is a big difference in rpm at any speed.

As pointed out, 33 tires will fit with little or no trimming on a stock suspension M1009.

Here is a link to a previous thread on this, shows where the right fender was being rubbed, and the bit I cut off to resolve it.
The picture below of my second 1009 (with the same tires) shows where I whacked the same basic spot but in the left front fender well. Didn't take much, that bit used to slant forward, I banged on it until it slanted back.
Again, a different tire wouldn't have rubbed at all, only the outermost lugs on these aggressive treads hit.

how much of a p.i.t.a is it to swap in a th700?

I seen a few people talk about it. I dont know the facts, but I guess the bellhousing is the same. The length of the trans. is a issue it will affect the rear and front driveshaft, also where it bolts to the crossmember.
I heard you should use a torque converter for a diesel, not sure if the 400 and the 700 have the same design.
I know the 208 transfercase was used on the 700 also, but I dont know if the 700 and the 400 have the same splines on the output shaft.
I guess those are the issues I can think of but I'm probly missing something.
