Noob questions about 33"s on stock 15x7 rims, with 2.5" lift

hey guys, sorry, i'm new to tire/wheel sizing, and i leave for a road trip on Tuesday so am in a rush to figure this out.

i just had a 2.5"-3" suspension lift installed on my '99 4WD Xtra cab (awesome toytec kit) and it makes my 31" tires look like mini-donuts. i'm looking to get a set of 33" BFG T/A KOs, but i have a few questions:

1) with the lift + 33" tires, my truck will be 4"+ higher than before. should i be very concerned about stability/tip-over with the higher center of gravity and tire flex? or is the difference fairly inconsequential?
2) will the 33x10.5 fit without spacers/adapters/mods?
3) should i even consider the 33x12.5? i know it's pushing the upper limit and would be a bit bulgey and wear quicker, but maybe it's worth the wider stance? but if these require spacers/adapters, it's probably not worth it.

thanks!

 

i also have 31' bfg at on mine with 2.5 of lifts. i think with the 33 on 2.5 will rub on the pitch well and at the lower front plastic bumper. hopefully someone can chim in more.

 

1) with the lift + 33" tires, my truck will be 4"+ higher than before. should i be very concerned about stability/tip-over with the higher center of gravity and tire flex? or is the difference fairly inconsequential? Yes they will fit with some trimming and no your not going to be tippy

2) will the 33x10.5 fit without spacers/adapters/mods? You will have to do a little trimming but no spacers or adapters.


3) should i even consider the 33x12.5? i know it's pushing the upper limit and would be a bit bulgey and wear quicker, but maybe it's worth the wider stance? but if these require spacers/adapters, it's probably not worth it. No don't mount a 12.5 on a 7" wide rim 8" is the min.

 

i guess i have another option, which is just keep the 31"s. are you happy with your tire size? ever wish you had 33"?
