I had my 33 inch tires before the 4 inch lift. My wheel wells are cut though. I believe Landpimp is running 33's on a stock suspension.
Here is a shot of After lift vs Before. Both with 33's. The 33's did not rub before the lift.
I am running the 33x9.5x15's. I chose them because I wanted a great wheeling tire that did not require power steering. I only miss power steering in some tight parking situations in parking lots. Have not had any issues on the trail. It's on my list for one day though.
A lot of people say Power Steering is the single best mod. My best mod was adding an Aussie Locker to the rear diff. The difference in wheeling capability was well worth it!
Found this and the proportions look right to me .33's fill the arches well and the 4" lift only gives them room to move . My trucks all got wider to offset moving the centre of gravity upwards by using wider negative offset wheels .
A quick google suggests theres plenty of options to do this
and having ridden in one with that lift that did have anti roll bars - it was not comfortable and on occasions you'd need stronger shocks or seasick pills.
I wonder if it had an over axle spring conversion Roger ? cheapest way to do it but adds forces beyond what otherwise stock suspension is set to deal with . I would expect any 4" lift kit to include uprated shocks and springs .
Its all personal preference of course and budget dependant , I'm just enjoying imagining I owned a 40 and how i would make it mine and therefore a little different from the rest as is my habit .
