I haven't experienced any rollover scares, or stability issues in my P520 with my ITP Utracross R 27x9-14's (on all 4 corners). My front width is 52 inches and my rear is 51 inches.
But, it appears the P520 has an advantage over the P500 in this regard....no rear stabilizer bar?
I've gone over some pretty crazy terrain with the taller tires...where I was expecting some rollover scares (especially reading this forum) but, the P520 managed it flawlessly. That said, I'm very very certain I can get this thing to roll over. I just need to throw caution to the wind, increase my speed and maximize my stupidity and I'll make it happen.
