Wheel\Tire Sizing for Beach..Help!

Hey All,

After spending a few days researching, I am humbly asking for some assistance.
First, the important info...

Currently: 2008 Trailblazer LT, on stock 18x8 wheels with 245/60-18s.
Goal: Gain ground clearance and traction for strictly beach driving (no offroad), minimize tire poke, no cutting\trimming if possible

I don't want to lift this thing to the sky, just get a bit of frame clearance to keep off the sand, and gain a whole bunch of tire so I can actually air down and get some traction.

If I go with a 2.5 inch lift all around, lengthened shocks in the rear, and wheel adapters (seem only to be able to find 1.25" nowadays), What is the optimal size wheel and tire for my goals? What are my width limitations if I am not looking for the tires to stick out from the body more than an inch or two?

Commonly I've seen 265/70R17 with 2.5 inch lift with no trimming. Is that my best option?

Any\all assistance is greatly appreciated!!

Hi! I too recommend that tire size. 2.5" lift would be fine but might as well go 3" like I did lol.
Just be sure to deflate your tires to the correct psi before driving in the sand!! I live on the beach and I understand the struggle :)
