Personally I wouldn't go over a 31" tire without regearing but out here I have a lot of mountains I am dealing with when I tow. Some guys swear you can go to a 32".

Take a look at my album and this thread http://gmtnation.com/f28/new-16-wheels-787/ I am lifted on on just under 31s. I have done a lot of hauling, like I said I have to climb mountains where I haul. Flatlanders on 32s and not hauling much don't need the torque as much.

For 16s, Id probably stick to 265/70R16 as a max size. They're 30.4-30.6" and fill out the wheelwells nicely. Not too big, not too small. Ive got a set on my 02, but it hasnt towed anything in 2+ years since I got the SS.

I routinely tow a 17.5' fish and ski fiberglass boat or a 14' travel trailer. My TB does pretty good if I use a little common sense and use 3rd gear in the hills. Since I have 3.73 gears with 285/75-16 my effective gear ratio would be a bit lower than yours with 3.42 gears and a 265/70-16. I would not recommend larger than a 265/70-16. I used 245/70-16 as the stock size in my calculation. Somebody correct me if I'm wrong. Here's my math:
Original Tire Diameter / New Tire Diameter X original Final Drive Ratio = New Final Drive Ratio
Final Drive Ratio is either 3.73 or 3.42.
Mine with 3.73 gears and 285/75-16: 29.5 / 32.8 x 3.73 = 3.35 ---Effective final drive.
Yours with 3.42 gears: 29.5 / 30.6 x 3.42 = 3.30 ---Effective final drive.
Happy towing!

I run 265/70-16's (30.6") and tow a 20' trailer up the mountain to Estes Park. That's a pretty serious incline, and I'm running over 5000 pounds on the trailer. It's not something I would do on a regular basis though, as I spend most of the trip wandering between 1st and 2nd gear.
On the other hand, driving through the hills in the area, I have no problems towing in 4th gear with these tires. I honestly wish I have 3.73 gears though, as they would be better suited for my occasional towing, and the fact that 90% of my driving is in-town -- but since I have a 4x4, that doubles the cost of doing a conversion.

What ever you do, just keep in mind that a lift will change the center of gravity which for towing will change the behavior of the trailer. You'll be more prone to sway issues. Take it easy the first time out with it and the boat after the lift and get to know the behavior a bit. Don't want to see you ruin a boating weekend by dumping the rig.

That is why you get a drop hitch to keep the trailer level. It will still effect your vehicle but the biggest problem with people towing with a lifted vehicle is the load not being on the trailer properly to compensate for a higher front end.

Thanks Alot Guys!
I have decided That I am going to stick With nothing over a 31" Tire. I am going to be keeping my Stock 17" Chomies, After much towing, This vechical has disapointed me Greatly!
After 1200lbs, and 300 miles, My Envoy Just didnt handle good. My engine has very little pickup when trailering and or hitting 70. I dont Know if its normal. Thanks Again!

Extremely simple. Cut one of the current lines to the cooler, splice in the new cooler and find a decent place to mount the new on. It keeps the factory and gives you the extra cool from the new one.
