17 inch vs 18 inch

[shrineboy]

I do have way more body roll than I used to, not because of my tires. I run those at 40 psi. Side walls are pretty stiff, even aired down to 25 they don’t squash much. When I went crossover steering I had to remove my sway bar. I can still run up our windy canyon highway at 50. Anyway, I got used to it, hardly even notice anymore.

Every single truck that I have put taller tires on has experienced more body roll.

Every time I have swapped out sponge-o-matic all seasons for an E rated taller sidewall I haven't. I guess it is relative, but unless you are going from something stupid like 20 down to 16 with the same gushy sidewalls as OEM I am not buying this as a significant dynamic.

Tire pressure and swaybar bushings I am pretty sure would make a bigger difference.

All other things being equal... A taller sidewall will result in more body roll. You are not comparing apples to apples.

Go with the smallest diameter that will clear your brakes.

I've got lots of body rolls too. Oh.... you guys were talking about driving dynamics.... Oops.

Ok, but you'll be missing out.

For the best mix like the OP wants, I think 18’s are the way to go. Look at something like the Continental TerrainContact. It will handle anything w/in your Acura’s abilities, and is at home on the road. General also makes a Grabber that is similar. Lots of WK2 (Grand Cherokee) people run these for light off-roading and love how quiet they are.

I ended up going to 17s with 245/75/17 Falken WildPeak AT.
Handled my recent hunting/camping trip very well, and I don’t find the road noise all that intrusive. Maybe because I listen to my music too loudly??? The road ride is very comfortable as well
