If you don't want to do a ton of trimming then stick with a 255 or at the widest an LT275/70/17 which basically looks the same as the LT285/70/17 for the most part and is only .4" shorter than the P285. My dream tire would be a 265/80/17 or 275/75/17. :) Something in that 265-275 width but 33" to 34" diameter. The 34x10.5 KO2 doesn't count because it is actually way shorter than 34" and the price is ridiculous.That’s exactly what I’ve been looking into. I don’t think I have a need for 35s. Plus, to make it right, I’d need to regear. At 33s, I could get away with the GM front lift kit. If I add a winch and bumper, maybe use the Peak suspension coils to handle the extra weight.
But the 255 option has me intrigued and sounds like a great option.
