For AT tyres, there is a Pirelli Scorpion ATR in the design 19" size. I've run MTRs on my late, great D3 HSE V8. I haven't had any problems with rims or with the MTRs, but can see how it happens. I can air down to 16psi for soft sand and the MTRs work much better than expected. However, if there's any rock about, the MTRs need to be inflated more than tyres with bigger sidewalls to prevent a rock from folding the tyre against the rim, at which point the wheel gets an impact from the rock and the rock wins. I run around 24-28 psi with the MTRs on rock, depending on the weight of the loaded D3.
What is more of an issue with the MTRs is the price, just below $700 each on my last purchase. Goodyear did have to make them for a specific model (the G4 D3) so the development cost is recovered over relatively few tyres, but that does nothing to remove the purchase cost pain.
The D3's used to have a widespread problem with oil in the brakes from the vacuum pump, which caused braking reduction. Alas, it seems that braking failures are now bigger problems at Toyota. I'm glad to no longer have to endlessly be retiming engines, checking valve lash, etc, but the modern computer-controlled complex systems, while capable when working have a "on-off" failure mode that can make things over-interesting!

I can honestly say that in my 12 months of owning a 2.7 TDV6 SE I have never wanted for more power.
but on a lease this should be less of a pain.
